The cutting on this Sphalerite clearly works in favor of its Reddish Orange, with light return kept centered and bright. Collectors who prioritize natural origin and a calm, consistent look will appreciate what this stone offers. A carefully cut Sphalerite in Cushion form weighing 21.73 carats displays Reddish Orange with VS clarity, offered as single, allowing light to move naturally across the surface. Free from enhancement, the stone retains its authentic internal structure. You can put this next to heirloom pieces and it will not look out of place.

True transparent sphalerite, when held up to a light source, should allow clear vision through the stone rather than appearing foggy or murky. Learn more about Sphalerite.
