Why Cognac?
Cognac and warm brown spinels are among the least commercially visible colours in the gemstone market — which is precisely what makes them interesting to designers and collectors who pay attention. The warm, golden-brown tone pairs naturally with rose gold and yellow gold, and the rarity of a natural untreated Mogok origin adds weight to what is already an unusual choice. No treatments. No enhancements. A stone for someone who knows what they are looking at.
