Why Cognac?
Cognac spinel is overlooked by most of the market, which makes it interesting to designers and collectors who pay attention. The warm golden-brown tone pairs naturally with rose gold and yellow gold, and the Mogok provenance adds rarity and character that commercial brown stones simply do not carry. Eye-clean at under a carat, this is a practical, affordable entry into a genuinely unusual colour category. No treatments. No enhancements.
