Product Details & Craftsmanship

Unheated sapphires represent a tiny fraction of gem-grade corundum found worldwide, making a 2.13-carat piece particularly desirable for collectors and lovers of rare stones. The precise cushion faceting maximizes brilliance, allowing light to bounce through the sapphire to showcase its shifting hues under varying natural and indoor light.

The visible internal inclusions are characteristic of untreated sapphires, offering tangible proof of natural origin without compromising the gemstone’s overall brilliance or structural integrity.

Whether set in 18k yellow gold to accentuate its warm green undertones or cast in platinum to highlight its crisp blue notes, this loose teal sapphire offers endless options for custom jewelry creation. Shiraz Jewelry offers complete bespoke design services to craft a custom setting tailored around this gem.
