The 36.83 carat emerald-cut tourmaline is an extraordinary, top-quality gem rubellite. The trade term “rubellite” is often used somewhat liberally to include stones that have a deep purplish pink to pink hue. However, true connoisseurs reserve the moniker for those very rare stones possessing a pronounced and saturated red base color with some warm or cool secondary hues. To find a red stone over 10.00 carats that has even “good” clarity is an exceptional challenge as this variety is almost always fairly included. The present example, weighing over 36.00 carats and exhibiting exceptional clarity in a highly desirable emerald-cut, is in an elite class of rarity. Dr. Arem acquired the stone in 1978 from a small find in Madagascar. It is very important to note that, while some pink to red tourmalines have been irradiated to improve their color and this treatment is undetectable, how and where stones are sourced can provide vital assurances. Dealing directly with local sources who managed the stone from mining to cutting and polishing, Dr. Arem avoided examples that passed through the major gem centers where more complex treatments are applied. It is his learned opinion that the incredibly impressive 36.83 carat rubellite offered here is a completely natural gem. The quality and size were notable enough that Dr. Arem included this stone as a prime example, illustrating it in his revered publication “Color Encyclopedia of Gemstones”, a noted reference for countless gemologists and gem enthusiasts.
