Blue Spinel

Blue Spinel is the rarest color of an already very rare stone. Referred to by some as a gemological unicorn. WARNING - There is now a known treatment for blue spinel to enhance color called cobalt diffusion where they impregnate the gem with cobalt making it appear to be authentic. They can still call the spinel natural spinel but they must not legally call it untreated. This treatment makes crappy spinel look like bright blue spinel. Too blue, for spinel, too blue for almost any natural gem. It makes a rare and valuable gem worth 1000.00 to 3500.00 a carat worth about 15.00 a carat, if that.

The best way to avoid being tricked by this treatment is to know who you are buying from and/or get a GIA certification. We buy a lot of blue spinel and can identify it by looking at it, and we know what treated material looks like. We also test random stones in each lot we buy for the treatment just to be positive we never sell you a treated blue spinel. We will always try to protect you from unethical practices and treatments.

We have copies of the random GIA reports done for specific lots and we have the actual gems that were tested and the report is included when you buy those gems. We only trust the GIA lab for testing blue spinel for cobalt infusion and other treatments. We accept no other labs opinion, period, especially not cheaply priced labs in or near the countries known to perform treatments on gems. We have to charge more for the gems that were tested and the good news is the report makes them worth considerably more. We will happily test your individual gem (at your expense,) but the chances of a treatment getting by us are very, very slim. We have one of the best supplies of the finest spinel on the market and we had all of our material recut to enhance their beauty even more. 

These gems are extraordinarily rare in sizes over 2 carats and get rarer as the size goes up at3 carats 4 carats and substantially at 5+ carats and substantially at 7+ carats. Gems over 10 carats are so rare you can expect to pay a lot of money.

This gem is a great investment gem because supplies are almost gone in all known mines and completely gone in many areas. One of the most beautiful natural blue gems on the planet and often as attractive as the finest sapphire. It is about as hard as sapphire so suitable for engagement rings and everyday wear.
