2.11 Ct. Blue Cobalt Spinel from Tanzania

A story begins beneath the Tanzanian sun where cobalt rich veins color the earth, and skilled hands coax rare crystals from their rocky homes, and this GIA certified Blue 2.11 carat pear shape blue cobalt spinel carries that origin in every facet. Mined in Tanzania, this gem arrived at The Natural Gemstone Company with a clarity of very slightly included when evaluated at eye level, and an intense blue that speaks of the mineral elements that shaped it. Unenhanced and honest in its natural state, the stone radiates transparent purity, and its excellent polish reveals the patient work of cutters who respected the crystal, choosing a mixed brilliant faceted style to balance fire and color saturation. The GIA certificate accompanies the gem, a formal testament that honors both its scientific character and the human hands that brought it to light.

As a pear shape measuring 11.24 by 6.99 by 4.13 mm, this cobalt spinel is an ideal canvas for custom jewelry, and its 2.11 carat weight hits a sweet spot between presence and wearability. The tapered silhouette lends itself effortlessly to a center solitaire, a dramatic drop pendant, or an elegant halo ring, and the mixed brilliant cut maximizes scintillation from the point to the rounded end, making it especially flattering in vertical settings that lengthen the finger. Because the stone is unenhanced and exhibits only very slight inclusions at eye level, designers can plan fine settings that showcase its innate color without concern for treatments, and the excellent polish ensures clean reflections, crisp facets, and a luxurious face up appearance. At The Natural Gemstone Company we imagine this pear shaped cobalt spinel becoming an intimate engagement token, a bespoke heirloom pendant, or a commissioned pair of matched drops, and we stand ready to collaborate with jewelers and clients alike to select the perfect mounting that honors the gem story from Tanzanian mine to finished jewel.
