3.66 Ct. Bluish Green Cabochon Sapphire from Ceylon (Sri Lanka)

This 3.66 carat oval bluish green sapphire is an exceptional statement of color and form, with dimensions of 8.99 x 7.07 x 5.69 mm, an opaque body, and a double cabochon cut that enhances its visual depth. Evaluated at eye level and graded eye clean, this gem displays vivid color intensity and an excellent polish, characteristics that immediately distinguish it from many commercial sapphires you will encounter. Originating from Ceylon, Sri Lanka, and treated by traditional heat enhancement, the stone offers the classic vitality Ceylon sapphires are known for, while presenting a smoother, more saturated appearance than faceted stones of similar weight. At The Natural Sapphire Company we select stones like this because they combine a rare balance of weight, color saturation, and surface finish, qualities that are often compromised in mass market offerings.

When you compare this bluish green cabochon to other stones on the market, several advantages become clear. Many sellers offer cabochons that are either too shallow or too heavily included, which can result in dull spots or inconsistent color under direct light. This piece, with its double cabochon form and excellent polish, avoids those pitfalls by providing uniform luster and a deep, velvety color that reads consistently from every angle. Compared to faceted sapphires of similar carat weight, the opaque double cab emphasizes a serene and more organic aesthetic that does not rely on brilliance or fire. Versus lower end material that has been overly dyed or synthetic substitutes that mimic color without natural depth, this natural Ceylon sapphire retains the subtle internal character and mineral integrity collectors value. The heat treatment noted for enhancement is an accepted practice within the trade, done to clarify and stabilize color, and it does not diminish the gemology or the lasting beauty of a well cut and polished natural stone.

Craftsmanship matters, and the double cabochon cut on this oval sapphire delivers both aesthetic and practical benefits. The symmetrical dome on both the crown and pavilion creates a cushion of color, concentrating the bluish green tones and delivering a pleasing play of light that is soft rather than sparkly. This makes the stone especially well suited to settings that protect edges, such as bezels or flush mounts, which are preferable for everyday wear and for pieces that require a smooth profile, like signet rings or pendants. Compared to single cabochon stones that can sometimes reveal matrix or internal growth lines when viewed in direct light, the double cabochon cut is more forgiving visually, while the eye clean clarity ensures those viewing the gem without magnification encounter a pristine surface. The excellent polish enhances tactile appeal and reflects the careful lapidary work involved, a level of finish that sets it apart from many stones sold online without thorough inspection. As specialists at The Natural Sapphire Company we can advise on settings and design approaches that highlight the cabochon form, ensuring your finished piece takes full advantage of the stone’s optical strengths.

In terms of value and uniqueness this 3.66 carat Ceylon bluish green sapphire represents a compelling choice for connoisseurs and designers alike. Larger cabochons with such vivid, evenly distributed color and eye clean clarity are uncommon in the current market, and this example brings a combination of size, polish, and origin that translates into both visual impact and long term desirability. Compared to more common offerings that prioritize carat weight at the expense of color saturation or clarity, this stone offers a more balanced and rare proposition. Its heat treatment is transparent and standard, applied to enhance the gem’s natural qualities rather than to dramatically alter them, and the Sri Lankan origin contributes to a pedigree appreciated by collectors who know the subtle differences between deposits. If you are seeking a distinctive center stone that reads as elegant, deep, and timeless, this sapphire outperforms many alternatives in its class.
