Why Brown Spinel?

Warm, vivid brown spinels from Mogok are one of the more unusual offerings in the natural gemstone market. The rich, earthy tone pairs particularly well with yellow and rose gold, and works beautifully in designs that call for depth without strong colour saturation. A matched trio of this quality is a rare commercial find — brown spinel sets in consistent sizes are not widely available in the UK trade.
