Antique Style Greenish Blue Sapphire Ring 0.70 Ct., 18K Yellow Gold

From the high, sky-blue riverbeds of Montana to the warm curve of a yellow gold band, this ring tells a story that begins long before it arrived at our bench. Deep in the alluvial gravels of Montana, pockets of corundum waited patiently, shaped by time and pressure into sapphires that carry the cool memory of mountain streams and summer skies. The oval greenish blue sapphire at the heart of this design, weighing 0.70 carat and measuring 5.58 by 4.69 by 3.40 millimeters, is a distilled fragment of that landscape. Its hue is not a single flat tone but a living color that shifts with light and angle, showing verdant hints where the stone catches softer daylight and deeper blue in shadow. That unique Montana origin lends a quiet authenticity to the gem, an origin story that connects the wearer to a place as much as to an object of beauty.

The sapphire itself has been shaped to bring out its most compelling traits. Cut as an oval with a mixed brilliant facet arrangement, it balances a lively play of light with the gentle elongation that flatters the finger. The mixed brilliant cut concentrates fire and scintillation in the crown, while longer pavilion facets preserve depth and color, resulting in an intense color saturation that feels immediate and alive. At eye level the stone is graded very slightly included, a clarity that speaks to natural character rather than perfection, and one that often enhances the gem’s individuality by creating subtle internal texture. The polish has been rated excellent, so every facet edge is clean and reflective, and the gem has undergone a standard heat treatment enhancement that stabilizes and deepens its color, a widely accepted practice that honors the stone’s best visual expression while maintaining its natural origin in Montana.

Set to complement the sapphire without overpowering it, the two white round natural diamonds flanking the center stone total approximately 0.08 carats, and are chosen for clarity grades of Very Slightly Included, VS1 and VS2, with a color grade of F. These diamonds read as bright, icy accents that frame the greenish blue center and add a crisp, lively contrast against the warm glow of 14K yellow gold. The subtle brilliance of the diamonds lifts the sapphire’s color, giving it a halo of light on either side that amplifies presence without becoming ornate. The setting itself is refined, with delicate prongs and a graceful gallery that allow light to pass through the stones, so that movement and ambient light play across the mixed brilliant facets and the diamond accents with effortless ease. The 14K yellow gold warms the palette, providing a classic backdrop that enhances greens and blues and flatters a wide range of skin tones.

This ring’s design has been conceived to enhance any outfit, from the most casual to the most formal, by focusing on proportions, contrast, and movement. The oval sapphire’s gentle elongation makes fingers appear more elegant when worn alone, while the low, yet airy crown ensures the ring sits comfortably under a cuff or the sleeve of a blouse. Pair it with linen and denim for a look that feels lived in and stylish, where the greenish blue reads like a happy echo of a favorite scarf or a summer sky. Wear it with a crisp white shirt and tailored blazer and the diamonds will lift the overall composition, bringing a subtle flash at the gestures that matter in meetings and conversations. For eveningwear, the deepened tones of the Montana sapphire harmonize with evening blacks and deep jewel tones, while the yellow gold frame makes the piece glow at formal events. Layer it between slim bands for a modern stacked look, or let it stand alone as an engagement or signature ring that carries a narrative every time you glance down.
