0.78 Ct. Bluish Green Sapphire from Montana

Imagine a single heart of the mountain caught and set to shimmer, a small world of bluish green fire that holds a memory of sky and river. This 0.78 carat oval sapphire, measuring 5.81 by 4.97 by 3.61 millimeters, sings in a voice both deep and clear, its mixed brilliant cut chiseling facets that scatter starlight and candlelight with equal grace. The stone displays intense color intensity, the kind of hue that looks different with every turn, at times a cool teal like a secret pool, at times a deep blue kissed by green, all carried on an excellent polish that lets the light slip and tumble across its surface. The clarity grade is very very slightly included, evaluated at eye level, a whisper of nature that makes the gem feel honest and alive. Enhancement, heat treated, brings forward the sapphire’s inner drama, and its origin in Montana gives it a provenance as wild and dignified as the landscape that formed it, a provenance that we at The Natural Sapphire Company cherish and love to share.

Set before the eye, this Montana jewel moves like tide and like twilight, a small universe cut to oval perfection, the mixed brilliant cut creating a constellation of tiny mirrors within. When surrounded by a halo of small white diamonds, the center stone’s bluish green depths become more luminous, each diamond like a tiny comet orbiting the sapphire’s core. In a solitaire, the oval shape elongates the hand, the gem catching light with an intimate, private fire that reads as elegant and refined. The very very slightly included clarity gives the piece character, a natural fingerprint that invites touch and study, and the excellent polish ensures that every facet sings. Imagine this gem held in a low bezel for everyday wear, the metal embracing the stone like a promise, or mounted in a classic prong setting to let the air around it breathe, each choice changing how the light moves through its intense color intensity.

To design around this bluish green sapphire is to compose with water and dawn and moss. Pair it with warm rose gold and you will soften the blue into a romantic teal, the metal adding a blush that plays against the stone like sunlight through trees. Choose yellow gold and the green notes will waken, giving the sapphire a vintage, earthy glow. Opt for platinum or cool white gold and the blues will deepen, the gem taking on a midnight clarity that is at once noble and mysterious. For companion stones, a halo of fine round brilliant diamonds will amplify sparkle, framing the oval with a corona of light that elevates the center without stealing its soul. Side stones of tapered baguette diamonds will lend architectural grace, creating a long, elegant profile. For color play, pair the sapphire with soft peach morganites for a tender, sunrise palette, or with pastel pink sapphires for a romantic contrast that reads like a garden at dusk. To emphasize the green undertones, small tsavorite garnets make a vivid, verdant companion, their intense green popping against the sapphire’s bluish core. For an heirloom piece, consider a three stone design with two oval or cushion cut side stones, a vintage filigree mounting, and a mixed metal finish that lets each element tell a chapter of a shared story.

This gem, born of Montana’s ancient earth and refined by careful cutting, is a conversation starter and a quiet confidante, a perfect centerpiece for an engagement ring, a pendant that rests near the heart, or a pair of bespoke earrings that sway with every whisper. At The Natural Sapphire Company we delight in creating settings that honor a stone’s origin and personality, and this 0.78 carat oval bluish green sapphire responds to thoughtful design with a singular grace.
