Why Cognac?
Cognac spinel is a warm, earthy colour that sits outside the conventional gemstone market — which is exactly what makes it appealing to designers and collectors who value character over familiarity. Eye-clean at 0.67ct with Mogok provenance, this stone represents genuine value in an unusual colour category. The golden-brown tone works well in rose gold and yellow gold settings, giving a jewellery piece warmth and distinction. No treatments. No enhancements.
