From the misted foothills of Ceylon Sri Lanka this 20.50 carat oval brown smokey quartz began its journey as a modest rough crystal, found by experienced collectors who know the riverbeds and pegmatite veins where the best quartz hides. The rough was carefully hand sorted to select material with exceptional transparency and natural color, then entrusted to a master lapidary who shaped it into an elegant oval measuring 20.10 x 15.04 x 11.58 mm. The cutter chose a mixed brilliant cut to balance weight retention and light performance, carving precise facets that create lively flashes while preserving the gem size. With a clarity grade of very slightly included evaluated at eye level the stone reads clean and clear to the viewer, and its medium color intensity gives a warm, versatile brown tone that complements both yellow and white metals. No enhancement was applied, and an excellent polish brings a crisp finish to every facet, so the gem arrives to you as nature intended, enhanced only by expert hands and The Natural Gemstone Company care.
Compared to other options on the market this smokey quartz stands out for a combination of size, cut quality, and natural origin. Many stones of similar color are heat treated or irradiated to achieve uniform tones, or they are cut shallowly to boost face up appearance at the cost of brilliance. This 20.50 carat gem retains real depth and optical life because of its mixed brilliant cut and superb pavilion angles, and because it is unenhanced it offers transparency and stability that treated stones cannot match. Clarity that is very slightly included at eye level means the gem looks clean in most settings unlike many commercial pieces that show obvious inclusions without magnification. The medium color intensity makes it ideal for a statement ring, a bespoke pendant, or for designers who want a large natural focal gem without the cost of rarer varieties. At The Natural Gemstone Company we focus on ethical sourcing from Sri Lanka and on honest descriptions that let you compare quality and value with confidence, and we are happy to advise on settings that maximize the beauty of this exceptional oval smokey quartz. Secure this rare combination of natural origin, significant carat weight, and expert cutting today, and own a piece that outperforms common market alternatives in both presence and integrity.
