7.84 Ct. Swiss Blue Topaz from Ceylon (Sri Lanka)

This Swiss blue topaz, presented by The Natural Gemstone Company, is a transparent emerald cut weighing 7.84 carats, with dimensions of 11.99 by 10.13 by 6.79 mm. The step facets of the emerald cut emphasize the stone's strong table and even color zoning, producing a clear, intense blue that remains consistent across the crown and pavilion. Clarity has been evaluated as eye clean at normal viewing distance, and the gem exhibits an excellent polish that enhances light return within the constraints of the emerald cut geometry. The material has undergone irradiation to achieve its Swiss blue hue, and its documented origin is Ceylon, Sri Lanka. The topaz displays a well balanced depth that suits a range of mountings, and with a hardness of 8 on the Mohs scale it offers good durability for everyday jewelry when properly set and cared for.

This gem is well suited to custom conversion into a variety of jewelry settings, offering versatility for designers and clients. For rings, a four or six prong cathedral or basket setting will secure the corners of the emerald cut while allowing the table to collect light, a bezel or partial bezel provides additional protection for frequent wear, and a halo of small brilliant cut diamonds will visually increase presence while complementing the blue tone. The shape and proportions adapt readily to three stone configurations, east west orientations, solitaire pendants, single stone cufflinks, and bespoke brooches. Metal choice will influence the presentation, white metals will emphasize the cool blue, yellow gold will provide warm contrast, and platinum will offer a premium, durable mounting. When planning a custom setting, consider a gallery aperture to maximize brilliance, a secure prong seat at each shoulder to protect corners, and the option of accent stones to balance size and color. Because the color is enhancement induced by irradiation, avoid exposure to high heat and strong chemicals during manufacture and use, and employ gentle professional cleaning when required. The Natural Gemstone Company can provide detailed images, measurements, and recommendations for prong count, bezel lip dimensions, and metal selection to facilitate a precise, durable, and visually appropriate custom setting.
