About the Item
A rare, collector level cobalt blue spinel from Mahenge, Tanzania, offered loose and unmounted by Merkaba Jewelry Beverly Hills. Weighing 3.07 carats and cut in an elegant oval, this gemstone displays the vivid saturation and lively brilliance that makes Mahenge spinel so sought after by connoisseurs. The color reads intensely blue with exceptional presence, a true centerpiece stone for bespoke fine jewelry.
Measuring 9.69 x 8.20 x 5.96 mm, the spinel has strong face up coverage and beautiful proportions, ideal for a custom ring or pendant where color and rarity matter most. Spinel is also valued for durability and wearability, making it a refined alternative to traditional center stones for collectors who want individuality and long term elegance.
This gemstone is accompanied by a Bellerophon gem lab certificate, adding confidence and documentation for a serious acquisition.
