0.39 Ct. Greenish Blue Sapphire from Montana

This transparent 0.39 carat oval greenish blue sapphire from Montana offers an elegant and rare presence, presented with precise measurements of 5.01 by 4.03 by 2.50 millimeters, a mixed brilliant cut, and a clarity grade described as very very slightly included when evaluated at eye level. The stone shows vivid color intensity with an excellent polish, allowing light to enter and reflect from its facets for a lively and dynamic face up appearance. As with many of the finest Montana sapphires, this gem has been heat treated to enhance its inherent color and translucency, and the result is a deep, complex greenish blue tone that shifts slightly with different lighting, revealing teal flashes and sea deep blue zones. At this size and shape, the oval silhouette offers a classic elongation that flatters the finger or the neckline, while the mixed brilliant cut balances scintillation and depth, making it equally compelling as a solitaire or as the central element of a custom composition, and at The Natural Sapphire Company we pride ourselves on matching these exacting characteristics with settings that honor the stone rather than overpower it.

When you imagine this Montana sapphire paired with complementary gemstones in a custom piece, consider contrast and harmony to bring out its greenish blue personality, a halo of small near colorless round brilliant diamonds set in platinum or white gold will enhance the stone by increasing perceived size and adding brisk white sparkle, the cool metal will keep the sapphire looking crisp and jewel like. For a warmer, more vintage inspired feeling, surround the center with tiny champagne diamonds or rose cut cognac diamonds set in rose gold, this contrast will amplify the green undertones and introduce a glow that reads modern yet timeless. For color play, flank the oval with matched pairings of mint tourmalines or pale green sapphires to create a soft ombre effect that leans into the stone s green side, or consider intense tsavorite garnets as accent stones to push the composition toward a vivid and botanical palette. If you prefer a bolder, contemporary statement, set two tapered kite shaped diamonds or salt and pepper side stones to form a three stone ring that emphasizes the sapphire s depth, alternatively a cluster style with mixed shapes will feel organic and artisanal. For earrings, matched ovals or a center sapphire paired with pear shaped diamonds will create movement and allow the gem to catch light with every turn, and for a pendant the oval oval sapphire sits beautifully in a low bezel for protection, or in a four prong setting to maximize light return and maintain a refined profile against the collarbone.

Design choices that respect the gem s provenance and optical character will deliver a piece that truly feels complete, at The Natural Sapphire Company we advise selecting metal colors and accent gems based not only on fashion but on how they interact with the sapphire s greenish blue hue and mixed brilliant cutting style. A simple three prong mounting in platinum lets the face up color breathe, while a delicate halo in yellow gold offers a vintage glow that warms the stone and suits those who favor a romantic aesthetic. For everyday wear a slim bezel delivers excellent protection to the girdle and reduces snagging, for engagement designs a four or six prong open head paired with a micro pave band gives balance between security and brilliance. Custom settings also allow us to place accent stones where they will complement visible inclusions if any, and to orient the oval to flatter the hand or the neckline, we can match melee sizes and colors precisely so that the small diamonds or colored accents sit in visual proportion to the 0.39 carat center, and we will recommend hand finishing and polishing approaches that enhance the sapphire s excellent polish rather than masking its natural character. Your search for a singular greenish blue Montana sapphire that is transparent, vividly colored, and beautifully cut can end here, because this oval marries rarity with everyday elegance, and together with The Natural Sapphire Company you will find the right setting, the right accents, and the right metal to make it unmistakably yours.
