Antique Style Blue Sapphire Ring 1.73 Ct., Platinum 950

There is an ancient and enduring quality to a well chosen sapphire, a legacy that reaches back through royal treasuries and sacred jewelry boxes, and this ring brings that history to life with a Ceylon blue at its heart. The centerpiece is a transparent 1.73 carat oval shaped blue sapphire, precisely measured at 8.00 by 5.95 by 4.36 millimeters, cut in a mixed brilliant style that balances scintillation and depth. Evaluated at eye level, the stone is eye clean, with vivid color saturation and an excellent polish that delivers a deep, velvety blue with lively flashes of brightness as it moves. The sapphire has been heat treated, a long established and stable enhancement applied responsibly to bring out the best of Ceylon stones, and its provenance from Sri Lanka links it to a storied tradition of gem cutting and collection. Surrounding the center are natural white round diamonds weighing approximately 0.426 carats in total, with clarity grades of Very Slightly Included, VS1 and VS2, and a color grade of F, chosen to provide a lively halo that amplifies the sapphire without overpowering it. The mounting is crafted in platinum 950, a metal that complements the cool tones of the gem ensemble and frames the design with quiet strength, and every detail reflects the exacting standards you expect from The Natural Sapphire Company.

Beyond beauty, the ring is built for endurance and everyday wear, an important consideration when you choose a piece meant to become an heirloom. Sapphire is second only to diamond on the hardness scale, which means a properly cut and set sapphire resists abrasion and retains polish far better than most colored gemstones. The mixed brilliant cut of this oval sapphire is engineered to combine durability with brilliance, dispersing light through a layered facet structure that reduces the concentration of stress at any single point along the girdle. The halo of round diamonds serves a dual purpose, it increases apparent size and sparkle, and it also provides a buffer around the sapphire, deflecting minor knocks that might otherwise impact the center stone. The use of platinum 950 elevates this protection, because platinum is denser and more ductile than common white gold alloys, it holds stones securely as prongs bed in rather than wear away, and unlike plated metals it does not require repeated re rhodiuming to maintain its white tone. The prong work and mounting design executed by our craftsmen at The Natural Sapphire Company are deliberately conservative where strength matters, with secure settings for both the center sapphire and each accent diamond to minimize the risk of loosening over time.

When compared to similar designs on the market, this ring stands out for a combination of material choices and classical construction that favor longevity. Many halo rings are offered in 18 karat white gold or lower grade alloys, which over time can show more visible wear, require periodic replating to regain their original white finish, and may need more frequent prong maintenance. By contrast, platinum 950 wears differently, it develops a patina that can be polished back, and the metal itself is not lost through plating, which translates to greater long term security for the stones. Some contemporary alternatives use very delicate open galleries or minimal bezels to maximize light, but those approaches can sacrifice edge protection, especially for softer or more inclusion prone gems such as emeralds or certain lower grade sapphires. This ring balances openness for light return with a substantial halo and robust prongs, giving it superior impact resistance compared with ultra minimalist settings. The heat treated Ceylon sapphire in this piece also offers a predictable and stable performance relative to untreated or fracture filled stones, which can be more vulnerable to thermal shock or require special care. For anyone considering daily wear, engagement, or a piece to pass down, the combination of a durable 1.73 carat Ceylon sapphire, well graded VS diamonds, and a platinum 950 mounting represents a practical choice among classic designs, and it is a confident statement of timeless elegance from The Natural Sapphire Company.
