1.80 Ct. Greyish Blue Spinel from Tanzania

This greyish blue spinel from Tanzania, weighing 1.80 carats and measuring 8.95 by 7.50 by 3.89 millimeters, embodies a quiet, ancestral elegance that speaks to collectors and lovers of classic design. Cut in an oval silhouette with a mixed brilliant faceted style, its intense color intensity and excellent polish allow light to dance across the stone, producing a refined brilliance that has been admired for centuries. Historically, spinel has been prized alongside the great gem species of the world, often adorning royal collections and sometimes mistaken for rubies in ancient crown jewels, a testament to its enduring esteem. This particular gem is untreated, with no enhancement, and has been graded very very slightly included when evaluated at eye level, offering remarkable transparency and only the most minute natural inclusions that serve as subtle proof of its natural origin. At The Natural Gemstone Company we take pride in presenting stones with traceable provenance, and this Tanzanian spinel is a fine example of nature’s unaltered artistry, finished to a level of polish that honors its legacy.

Beyond its historical resonance and classic form, this spinel is also exceptionally well suited for everyday wear, an important consideration for anyone seeking a piece to become an heirloom. Spinel rates an 8 on the Mohs scale, which gives it strong resistance against scratches from routine daily activity while retaining a pleasing toughness that tolerates the small knocks and abrasions of frequent wear. The mixed brilliant cut enhances the gem’s structural symmetry and dispersion of light, reducing the visibility of internal features and reinforcing its visual stability in jewelry settings. With basic care, such as cleaning with warm soapy water and a soft brush, avoiding harsh chemicals and extreme temperature shocks, and having settings checked periodically by a jeweler, this spinel will maintain its tone and polish for decades. For those drawn to time-honored beauty combined with practical durability, this Tanzanian oval spinel from The Natural Gemstone Company is a compelling choice, ready to be set into a ring, pendant, or pair of earrings that will be cherished now and passed on to future generations.
