6.90 Ct. Yellow Zircon from Ceylon (Sri Lanka)

Born from the ancient alluvial gravels of Ceylon Sri Lanka, this yellow zircon carries a story that begins deep in weathered rock and riverbeds that have yielded gems for centuries. Hand recovered by experienced miners in a region famed for its gem lore, the rough was selected for its notable transparency and color potential. At The Natural Gemstone Company we trace that journey from the river to the workbench, where master cutters assessed the piece and revealed its inner fire. The result is a beautiful transparent 6.90 carat cushion shape yellow zircon, faceted with a mixed brilliant cut, measuring 11.05 x 9.29 x 5.89 mm, with a clarity grade very slightly included evaluated at eye level, medium color intensity, and an excellent polish. A careful heat treatment was applied to stabilize and deepen the yellow hue, a discreet enhancement that honors the gem while enhancing its visual appeal.

The cutting process transformed a humble rough into a gem that sings with light. The mixed brilliant faceting pattern was chosen to maximize both brilliance and fire, producing an interplay of scintillation and spectral flashes that sets this zircon apart from more common yellow gems. Compared to citrine and yellow topaz this zircon displays greater dispersion, sending sharper flashes of rainbow colors across its crown. Against sapphire and other corundums it offers a different kind of show, with an immediacy of sparkle and lively fire that corundum rarely matches. Even when placed beside a diamond it holds its own, because zircon combines a high refractive index with remarkable dispersion, producing a lively, radiant presence that feels more animated than many stones in the same color family.

This gem is not only a technical achievement but a piece of cultural continuity, a Sri Lankan treasure refined by modern lapidary skill. The very slightly included clarity reflects natural character while remaining eye clean at normal viewing distances, and the excellent polish ensures each facet returns light with crisp precision. Offered by The Natural Gemstone Company this 6.90 carat cushion yellow zircon is a statement of provenance and craftsmanship, a gem that carries the warmth of its island origin and the brilliance of expert cutting, ready to be set and to begin its next chapter in a piece of jewelry that will be treasured for generations.
