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

This beautiful transparent Swiss blue topaz offered by The Natural Gemstone Company is an 8.65 carat emerald cut gem, with precise measurements of 13.96 by 10.01 by 6.98 millimeters, an intense color intensity, and an excellent polish. Originating from Ceylon, Sri Lanka, this topaz displays a vivid Swiss blue hue that is the result of careful irradiated enhancement, a standard and stable treatment in the trade that produces consistent and durable color when properly set and cared for. The clarity is graded very slightly included as evaluated at eye level, which means minute inclusions are present but they do not affect transparency or the gem s overall brilliance when mounted. The emerald cut and the high quality polish create crisp step facets and broad light planes that emphasize even color distribution and make the stone appear clean and elegant to an informed viewer.

For custom jewelry designers and educated buyers this gem is exceptionally practical and versatile, thanks to its generous dimensions and classic emerald cut. The rectangular outline and well controlled pavilion, with a depth ratio of approximately fifty eight percent based on the provided proportions, provide a balanced optical performance that favors both face up color and internal light return, making it ideal as a striking center stone for a ring, a sophisticated pendant, or matched pairs for statement earrings. At 8.65 carats the stone offers substantial presence without requiring an oversized mounting, allowing for a variety of setting styles including four or six prong baskets, bezel settings that protect the corners, and halo designs that enhance apparent size while showcasing the clean step cut. Topaz rates eight on the Mohs hardness scale, offering good daily wear durability when set with consideration for the gem s long axis and protected against hard knocks, and like all irradiated topaz it is best cared for by avoiding prolonged exposure to high heat and harsh chemicals. Buyers who value documented origin, stable enhancement methods, and precise cutting will find this Swiss blue topaz from The Natural Gemstone Company a reliable and attractive choice for finely crafted custom jewelry.
