Tanzanian Spinel Gems
When it comes to gemstones, natural spinel isn't particularly well-known, especially when it comes to commercial retail jewelry. In fact, for most of time, spinel was mistaken for other gems, such as varieties of corundum, like the curious case of 'The Black Prince's Ruby'. Spinel is highly prized for its excellent hardness (8 on Mohs scale), and compared to precious ruby, spinel has greater dispersion (fire) and brilliance. Spinel is also one of the few singly refractive gems, which gives it the ability to exhibit intense colors with a special level of purity. Best of all, spinel is never treated unlike sapphire and ruby, making it one of the best untreated gemstones on the market.

Historically, Burma (Myanmar) has been the world's primary source for fine quality spinel, which is also one of the reasons it has been a difficult gemstone to source for most buyers. However, since the last decade, spinel has become much more openly available because of Tanzanian deposits being commercialized. Burma is still the leader when it comes to the rare red spinel, but Tanzania is becoming one of the top producers for other attractive spinel colors, such as pink, violet, blue and unusual orange, as well as a bright purple variety too. Most spinel is very hard to find in gems weighing over 1 carat, but many spinel gems from Tanzania are being discovered in very large sizes, often weighing over 5-10 carats. Nowadays, in addition to Burma and Tanzania, spinel is also mined and sourced from Sri Lanka and Tajikistan, usually alongside ruby and sapphire.

I love that I was able to find a site that offers REAL gemstones. I love the pictures provided of the gems so I can look at each one from different angles, I love the variety of gems on the site & I love the ability to narrow down my search to look at certain gems that fit my criteria.

My experience with gemselect was awesome so far. I had a few questions about their website and making orders and they replied quickly and were happy to help. I have not received the items I ordered yet as I just ordered them this morning. Although, I truly feel I am going to be a very happy customer once I do receive my items. Gemselect guarantees all their items and have a great return policy just incase. The have a vast selection of all kinds of stones and not to mention their prices are much better than some other websites. Thanks Gemselect I’ll be doing business here from now on!

Great selection. Love the many learning features like articles and gem information. Prices competitive for natural stones. I do miss not having a selection of lab-made stones, CZ’s, etc, which are useful when price and cost are factors.

length x width x depth,
except for round stones which are;
diameter x depth

Select gems by size, not by weight!
Gem varieties vary in density, so carat weight is not a good indication of size

Note: 1ct = 0.2g
