Why Teal Blue-Green?

Teal spinel is a colour that professional buyers specifically seek out and rarely find in this quality. The blue-green combination in natural spinel comes from trace elements within the crystal structure — it cannot be replicated or induced through treatment. At nearly 1.8 carats, eye-clean, from Mogok, this is an exceptional example of a colour category that most gemstone buyers will never encounter in this quality. Highly suited to a high-profile bespoke commission or a serious collector's acquisition. No treatments. No enhancements.
