A substantial cognac spinel from Mogok — 1.81ct, eye-clean, with a well-proportioned 6.8 × 6.2 × 5.0mm outline. The depth on this stone is excellent, giving it good light return and a rich, warm face-up presence. At this size, a natural untreated cognac spinel with eye-clean clarity is genuinely uncommon.

Why Cognac?

Cognac spinel occupies a niche that most mainstream gemstone buyers overlook — which is precisely what makes it valuable to those who do pay attention. The warm, golden-brown tone sits beautifully alongside rose gold, yellow gold, and warm metal finishes. A stone of this size, clarity, and Mogok provenance is not something you encounter regularly. For a jeweller seeking an unusual centrepiece or a collector building a range of rare colour spinels, this is a significant find. No treatments. No enhancements.
