Antique Style Bi Color Sapphire Ring 1.78 Ct., 18K White Gold

This ring centers on a transparent 1.78 carat oval bi color sapphire with dimensions 7.98 x 6.24 x 4.51 mm, cut in a mixed brilliant style to balance color display and lively scintillation. Graded eye clean at standard viewing distance, this Montana sapphire exhibits intense color saturation and an excellent polish, attributes that matter to the discerning buyer who values both visual impact and long term durability. Montana is renowned for producing distinct, naturally heated sapphires with complex color character, and this piece benefits from that provenance, offering a rare bi color expression that is uncommon in commercial supply. For context, sapphire rates 9 on the Mohs hardness scale, so when set in a well made mounting the stone provides enduring wearability as well as investment appeal.

Flanking the center sapphire are white tapered baguette diamonds totaling approximately 0.28 carats, with clarity graded Very Slightly Included, VS1 and VS2, and a color grade of F. The choice of tapered baguettes complements the sapphire by providing crisp linear contrast and a refined profile, while the VS clarity ensures eye clean performance and excellent light return. The entire composition is set in 18K white gold, a metal that enhances perceived whiteness of the side diamonds and offers a secure, elegant setting for the oval sapphire. At The Natural Sapphire Company we emphasize traceable origins, precise grading, and hand finishing, so this ring arrives accompanied by confident descriptions of cut, clarity, and country of origin to satisfy collectors and buyers who require factual documentation.

Customization options allow this ring to become a one of a kind heirloom tailored to personal taste, and The Natural Sapphire Company can guide each modification with gemological rationale. Options include changing the metal to 18K yellow or rose gold to warm or enrich the sapphire tone, replacing side stones with round brilliants or trapeze cuts to alter light behavior, increasing total diamond weight, or adding a halo to intensify apparent center size. For a period or bespoke look, we can add hand engraved or pierced gallery work, switch the prong style to a bezel for extra protection, or recut the sapphire into a different oval proportion to emphasize depth or table size. We also offer independent certification and bespoke matching wedding bands to ensure cohesive aesthetics and enduring value.
