pink spinel – The Gemstone Project

Evaluating a Neon Pink Red Mahenge Spinel

Posted on September 26, 2016September 25, 2016 by grayspinel

This week’s blog is an evaluation of a 3.21ct Mahenge spinel that I did for a client recently. The stone was brought in from Mayer & Watt, a wholesale dealer where the advertised MSRP is $5,256/carat. The following is a direct copy and paste of my email.

Color:

It is always interesting to see how different stones look when up against other stones of similar colors. For this pear, I pulled out the large Mahenge reddish-pink cushion I have, the small Burmese pink-red, a red-red oval, my red spinel band, and my pink-pink Mahenge spinel. So this one is interesting because up against the more pink stones, it looks more red, and when it’s up against a red red, it looks pink. Overall it’s strongly saturated, medium in tone, with the slightest hint of orange when compared to pinks that are more blue-toned.

Inside

Outside

Inclusions:

My biggest concern going into it was the inclusion. As I think I mentioned in a message I sent you earlier, in some lighting situations, it’s more obvious than in others. Right now it’s about 18 inches from my face, and even though I know where it is, I have difficulty finding it. I think that it would be very close to where a prong would sit to hold it, so once set, it may become even less obvious. I just put it under 14x magnification and it looks as though there is a cluster of 3 bubble inclusions, which are typical for the Mahenge location. They don’t pose any problems for setting, they don’t even come close to reaching the surface. The largest one has a slightly larger cloud around it that’s typically not visible except when backlit, which I have attached a picture of. They are all clear or white inclusions, probably a negative crystal inclusion and two gas bubbles. Even with the three inclusions, I would say that this is a very clean example of Mahenge material.

Cut/coloration:

You had asked about zoning earlier. There isn’t any zoning, but as is pretty typical with pear and marquise cuts, the color tends to concentrate on the tips, as a result of the cut. This one is actually pretty evenly colored, with just a slightly deeper color on the tip. As far as cut, this is a really well cut pear. There isn’t any windowing, and there isn’t an abnormal amount of tilt windowing. If anything, I’d say that there is less than the typical amount of tilt windowing. There does not appear to be any bow-tie or large amount of extinction.

Fluorescence:

It glows a bright red under UV light.

Overall I’d say it’s a pretty exceptional stone. The only hesitation I would have would be the inclusion, but that’s really a matter of personal preference – I’m ok with inclusions so long as they aren’t detrimental to the overall look of the stone.

The Vivant Ring

Posted on May 23, 2016May 22, 2016 by grayspinel

One thing I sometimes struggle with is keeping it simple. Sometimes I find myself adding details and thinking, “This is perfect!” and then going back and thinking, “Why did I add so much?!” I always try to remember that Coco Chanel quote:

“Before you leave the house, look in the mirror and take one thing off.”

Wise words from an impeccably fashionable woman. So while the Vivant necklace is a modern take with Art Deco appeal, I decided to keep the Vivant ring an echo of some of the details from the necklace, and lend towards classic simplicity.

The stones chosen for this setting were chosen to add a little bit of drama via color, with a neon pink Mahenge spinel, and two antique Old Mine Cut cushions (because antique cuts in diamonds are my favorites!) as the perfect classic accents.

Typically one of my favorite views, because it shows off so many details of a ring setting, and how they flow together.

The ring ends up at 2.64ctw of diamonds (antiques are .99ctw, melee are .10ctw) and spinel (1.55ct) and was made of 18kt white gold. This setting will be available (and tremendously adaptable!) for your own stone or stones, of any shape and size. I am also able to source stones, because pairs are not exactly easy to find sometimes!

And ending with the fluidity of the shank, and the slight split shank transition.

Feature: Dan and Cindi Stair

Posted on March 14, 2016March 13, 2016 by grayspinel

Daniel and Cynthia Stair are the owners and gem cutters at Custom Gemstones and I have known them for many years, after first striking up a conversation when I was looking for my engagement ring stone. I recently reached out to Dan with a whole bunch of questions and he answered every single one! Something that I really love about their website is that they take before and after pictures and it’s fascinating to see how the rough turns out, and recently started posting video of every single stone that goes up on their website.

How much of the cutting do you each do?
I cut full-time and do one or two per day. Cindi works at the local hospital, so she only has time to cut a few stones each month.

What are your favorite stones to cut?
That’s a tough question. If I had to pick one, it would probably be natural sapphires. However, I really like tourmalines, spinels and garnets too. I tend to favor higher RI or more dispersive gemstones, regardless of the hardness of the stone or the fact that harder stones take a little longer to cut. They also last longer in jewelry, so that’s something I feel good about. I don’t like to hear that people have rings made and then the stones get all scuffed up.

Do you have a favorite shape you like to cut? Or a favorite cut design?
No. I don’t like cutting pears, but other than that, don’t really have a favorite. Variety is a good thing when it comes to cutting stones.

Do you typically cut more from diagrams or more by instinct?
Actually, I only use diagrams less than 10% of the time. I usually cut using a “style” such as step cutting as with emeralds or Asscher cuts, or brilliant cutting as with Portuguese, standard round brilliants, etc. I also do a lot of radiant or princess type cuts if the stone is shallowish, and scissors cuts if it’s deeper in shape. While I work, I figure it out as I go and make notes about the angles, index gear (rotational) settings, etc. as needed so I can remember what I did when I go back to prepolish, then polish the stone.

How did you get started cutting gems? What did each of you do before?
I was a photographer, writer and graphic designer for a large fishing lure manufacturer, and also did a lot of work for other area business and print shops when they needed full color printing done. Back in the early 1990’s, I was probably one of the very first people to successfully use a desktop color computer for production of things like catalogs, magazine ads, etc. Cindi was a housewife for many years and a gem collector. She started cutting stones about ten years ago. I started in 1998 if I remember correctly.

What’s your favorite type of customer?
I don’t really have a favorite type of customer other than maybe people working on engagement ring projects because it’s fun to be a part of that, or gemologists because it’s nice to work with someone who knows a lot about gemstones.

What’s the percentage split between commissions vs what you choose?
It’s gotten to be about 50/50. Right now, we’re backlogged about a month with other peoples stones to cut, but also have to keep the ebay store and regular website interesting. I try to cut one of my own, one for someone else, one of my own, etc.

I noticed that you added videos of your stones to each listing. What brought that on?
I was getting a lot of request for “more photos”, particularly from pricescope.com members. What they don’t realize is how much time that takes and often, they were more looking for reasons to not buy a stone than anything else. So, I decided to try videos because that shows so much more about how a stone looks in person that still photos alone. Since I started doing that, I have noticed a huge reduction in requests for additional pictures as well as a major decrease in how many people get stones in the mail then decide to return them because they aren’t exactly as expected. Neither the photos nor the videos are perfect, but between those and the written description, a person should be able to get a pretty thorough idea of what a stone will be like in person.

You seem to have gained quite the reputation in recent years for recutting less than perfect stones, or damaged stones. How did that come about?
I used to send all those projects to other cutters, but started getting complaints that stones were being held for six months or more and the cutters were not returning emails. So, I finally decided to do the work myself rather than referring people to others that did not provide a good service. Since I have cut thousands of stones, and have that experience, I was able to develop some cutting concepts to fix a lot of the commercially cut stones without losing a ton of weight or having to do total recuts. The tops are usually not too badly cut. The pavilions are almost always 90% of the problem so learning to fix those has been the real key to improving the stones. As far as reputation goes, I really can’t say much about that other than I always try to do a good job and keep the overall value of the stone in mind so people don’t lose money on their gemstone investments.

How long does each stone take to cut? Do certain shapes take longer to cut?
Most smaller stones that cut to be 2 carats or less take 2-3 hours to cut. Bigger stones take longer, but not proportionally so. For example, a two carat finished garnet might take three hours, and a 10 carat more like 5 hours. simple shapes like rounds, squares and emerald cuts are fastest. Shapes with long curved sides take a bit longer. Examples would be ovals, pears, marquise cuts, etc.

What’s each of your favorite colors? Do you tend to try to cut those more often?
After all the years of graphic arts and now colorful gemstones, I have no favorite color. I don’t, however, like olive green or brownish pink colors. Cindi’s favorite colors are pink and green. She tends to like all colors, even some of the “ugly” ones, except red.

How often do you cut stones and keep them?
Me, less than one per year. Cindi, every few months. I very rarely keep a stone. I have a nearly flawless emerald, some opals and a blue to pink color change garnet that I’ve kept. After 17 or so years, I only have about 10 stones total…if that. Cindi, on the other hand has hundreds.

Does Dan have any jewelry made with the stones he has (Or Cindi) cut?
Yes. I have a silver ring Cindi made for me using a welo opal and a Tripps setting. I also have a small blue Australian sapphire that I cut in my simple, comfort fit wedding band.

How do you manage working together as a couple? How did Cindi get started and involved?
We both love gemstones in general and met when she start collecting stones I was cutting. Oddly, we work together very well and almost never fight or argue about anything. Cindi got started cutting gemstones as a hobby, which is how I got started also.

What is your favorite stone that you ever cut? Did you sell it or keep it?
I’m not sure I have a favorite, but the first one I ever kept for myself was an almost flawless, untreated Colombian emerald that even shows dispersion or spectral color flashes in sunlight. I am fond of this one because of the clarity. The somewhat odd step cut pear shape isn’t necessarily what I like about it. Under magnification, I could only spot three little specks of “jardin”.

What’s the weirdest stone you’ve ever cut?
Cindi has a really unusual gray tourmaline that is almost a charcoal color and super dispersive that I cut about 13 years ago. The thing has big spectral flashes coming out of a completely gray colored stone.

Whatever happened to those corpse colored tourmalines you had listed? Weird as it may sound, I’m sorry I missed out on them…
The first of the two “corpse” colored tourmalines was purchased by a nurse (funny huh?). I can’t remember who bought the second one.

A huge thank you to Dan for taking so much time to answer all of my questions and being so frank with his answers. Most of the images in this post were taken from the website, of some gemstones that are currently for sale (minus the pear emerald and the “Ugly Tourmaline”!) I have a particular weakness for Dan’s step cuts!

Lessons in Gemstone Buying

Posted on September 28, 2015October 6, 2015 by grayspinel

Back in January, I had posted about what to look for in looking to buy a gemstone. This is kind of an addendum to that.

– Don’t be afraid to ask too many good questions. One of the problems I often come across is that people are asking questions, but don’t understand the answers they are getting. If you don’t understand something, you should ask the vendor. I often will take massive amounts of time explaining things, so that even if a person walks away without buying something from me, they are more educated. A lot of vendors aren’t willing to do that, so you should take advantage of a person who is willing to share their knowledge. I’m a firm believer in “Leaving a place better than how I found it” which means if you ask me a question, I’ll do my best to educate you even further than just answering the question you’ve asked. Get educated about your purchases! You’ll make better, more informed purchases and likely save yourself time and money!

Treatment. Size. Clarity. Origin. Modifiers. Things like that.

– A better understanding of general colored stone terms (as opposed to diamond terms) and terms when describing rings and pendants. Again, and I can’t reiterate this enough, ask questions. If you don’t know what something means, ask! If they don’t know the answers to your questions, walk away until you find someone who does.

– Not verifying the return policy because sometimes what’s online isn’t current or detailed enough. You should always verify the return policy before you make a purchase.

– Not seeing the gem in various lighting conditions. Different light temperatures are going to make the stone look different. You need to make sure that you are happy with all of the stone’s different looks. Or, if not all of the looks, at least most of them. A stone isn’t going to look nice in a pitch black room if you can even see it at all!

Incandescent.

Diffused daylight.

– Always put something on hold before discussing it publicly. There are people out there who might see what you are looking at, and buy it out from under you. Most vendors work on a “first come, first served” basis. If you don’t put something on hold, and then post about it publicly it might just sell out from under you.

– Expecting flawless or loupe clean clarity, especially in gems such as spinel, emerald, ruby and sapphire. If you want one of those to be flawless, buy synthetic.

Not flawless, but it is eyeclean. Green Garnet.

– Don’t go to multiple sources looking for the same stone. This industry is very small. It is nothing but frustrating if you ask multiple people for the same thing, and they happen to start talking, and discover that they are looking for the same stone for the same client. Often, they will both give up on the search.

– Depending on the type of gem box that your vendor uses, you will probably want to open them upside down, above a soft surface, such as a low pile carpet, or best, on top of a made bed.

I know of too many people who have opened a box outside, and the gem falls into the grass or through slats in a deck, never to be seen again. Also, use something thin and flat to open the gem box.

I typically grab whatever is available, in this case, a ruler.

They put little slots on the sides to slide something in, and twist it to open.

Little twist of the ruler and it pops right off!

The end of the gem tweezers are best, but you can use thing like paper clips just as easily.

These spinels are safe and sound, in the lid of their box.

– You should look at a gemstone on your hand. I don’t have any gemholders, and I don’t suggest that people use them either. The spring type (the ones that look sort of like a ring) can very easily and very badly damage a stone.

I know that there are more tips and tricks for gemstone buying, but these are a good start. The absolute best tip I can give though is to buy what you like, and don’t be swayed by the “trade ideal”. If you don’t like what the trade finds to be ideal, you’re more likely to get a better deal on what you do buy.

Random note! Since I’ve been getting a ton of inquiries about the coupon code for my etsy store I decided to post it again, so here it is: “AUTUMN2015” (no quotes). It is good for 15% off purchases of $100 or more until November 1.

Next week is going to be all about the new line! By next Monday, all of the pages should be up for six of the rings, so make sure and keep your eyes peeled this week – Aurore, Exaltée and Feuilles Dorées will make their online debut!

Gem Blast: Red Spinel Melee

Posted on January 1, 2015December 22, 2014 by grayspinel

Bringing in the New Year with a bright bang! Here are some red spinel melee! I’ve had plans for these little guys for years, but they WILL be set in 2015. Famous last words. Hah!

I bought these stones with my husband after a great Vietnamese lunch. We popped over to the local gem store and I spotted these beauties. He keeps asking me why I haven’t set them yet, and I don’t have an answer besides that I haven’t gotten to it yet.

They are mostly red or red-pink, and really remind me of the color of Maraschino cherries as a group. Some are more pink, and some are more red. Since spinels are so rare, I accept their differences. Once set, I doubt the color differences will be noticeable.

Taking these photos allows me to see and appreciate the variations in color and cut. Each stone is special in it’s own way.

There is something so satisfying to me about tossing little stones around like confetti and taking pictures of them. I love capturing their tiny details, even more so than larger stones.
