Evaluating a Neon Pink Red Mahenge Spinel

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.

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.

Red Spinel

So I’ve posted some (a lot) of pictures and several blog posts on red spinel, and even have some running as banners along the top of my blog. Spinel is one of my favorite gemstones, mostly because it produces the best gray color, but also because it has an almost metallic sheen to it sometimes. Spinel is very good at having a variety of colors, I’d go so far as to say it’s right up there with sapphire, tourmaline and garnet with the rainbow of colors it comes in.

Now, I’m not a huge red person for myself, but red spinel has slowly been working on that for me. I like red spinel so much that the color red has been slowly wormed into my collection.

I also have a few international friends that are seeking their own red spinels, and I have received red spinel for them and evaluated them so they don’t have to take the risk and time of international shipping, which is beneficial for both them and the vendors of said stones. I really enjoy doing this and I wish they’d utilize me more often!

Red spinel melee can vary a bit, and I swear it is on my list to get mine from my gem store set sooner rather than later. I said in this post that I would set them in 2015. We’ll see how the year progresses, but at this point I’m going to aim for more like 2016, since all of my jewelry money is being funneled into putting my jewelry line together.

So one of the things about red spinel, is that it used to get mislabeled as ruby precisely because of it’s rich red color. The Black Prince’s Ruby is the best and most widely known example of red spinel being mistaken for a ruby, but it is certainly not the only one. One really fantastic thing (in my opinion) about red spinel is that it doesn’t have the fine inclusions that ruby does, so unlike most ruby, spinel actually sparkles, instead of the glowy velvety look of ruby.

Now, red is one of the most highly sought after colors of gemstones, if not THE highest sought after color. Ruby has traditionally been the most expensive red gemstone, and that’s not likely to change any time soon. Red spinel, on the other hand, has been going and will likely continue going way up in price, especially as it gets to be more popular and mainstream. It is already rivaling ruby on the pricing plane, and yet, it is still incredibly difficult to find quality pieces. As with all gemstones, there is a price premium that accompanies stones of larger sizes.

I didn’t really bring up a lot about modifiers in this post because the red hue was exactly what my friend was looking for, but in reds it is very important because they can mean a big price difference for what some might see as being a very small variation. Red usually has some kind of color modifier and the most typical are orange, blue/purple, pink and brown. The most commonly forgivable modifier is pink, since pink is a lighter toned red, but some people can excuse purple/blues and oranges because of personal taste and/or budget. Browns are typically going to be the most economically priced, while pure reds are going to be astronomical.

Red spinels are most commonly found in three different areas: Vietnam, Burma and Mahenge, Tanzania. Mahenge spinels have in the past ten years or so been coming out with the intense hot pinks and reds that display tons of red fluorescence under UV, which enhances it’s color under UV lighting conditions and causes it to appear to have some “glow”.

I keep hearing buzz about ultra red “Jedi spinels” but I haven’t taken a great interest in them because I know from what I’ve heard that they are going to be astronomically expensive, that is, IF you can get your hands on any of them!
