3.17 Ct. Blue Star Sapphire from Ceylon (Sri Lanka)

Discover an exceptionally rare blue star sapphire from the famed mines of Ceylon Sri Lanka, offered exclusively through The Natural Sapphire Company. This opaque oval gem weighs 3.17 carat and measures 8.06 by 6.53 by 5.87 mm, dimensions that provide a commanding presence while remaining eminently wearable, a perfect balance for those who desire a noticeable yet elegant statement. Cut as a classic cabochon the stone s domed profile has been masterfully shaped to reveal a clear six ray asterism that glides across the surface with movement and light. The medium color intensity gives the blue a serene but definite character, a hue that reads as sophisticated under indoor lighting and enthralling in daylight. Evaluated at eye level the clarity is graded as slightly included, a natural feature that in star sapphires often contributes to the depth and definition of the star, rather than detracting from the gem s beauty. An excellent polish enhances surface luster and increases the contrast of the star, while the assurance of no enhancement preserves the gem s natural story and rarity. Pieces of this character, with Ceylon origin and an unaltered treatment status, are seldom available in the market, making this star sapphire a true collectors gem and a meaningful centerpiece for a bespoke creation.

The size and clarity of this 3.17 carat oval star sapphire make it ideal for a statement piece that is both dramatic and refined. The generous dimensions and the substantial cabochon height allow the asterism to become the literal focal point, a luminous six ray star that appears to float at the surface, commanding attention without overpowering the wearer. Slight inclusions are in fact often welcome in natural star sapphires because they act as the scaffolding for the star s light phenomenon, creating a distinct and authentic chatoyancy that laboratory altered stones cannot replicate. With an excellent polish the reflections are crisp, and the star remains visible from a range of viewing angles, a property that translates beautifully into rings, pendants, and bespoke brooches. For a ring setting an open gallery or a subtle halo of small diamonds can enhance the perceived brightness of the star while protecting the cabochon profile, for a pendant a minimalist bezel can showcase the gem s form and let the star catch the light as the piece moves. Because the stone is unheated and retains its natural finish, any custom setting you commission will preserve and celebrate the gem s original character, creating an heirloom quality jewel that tells a story of provenance and authenticity.
