1.80 Ct. Greenish Blue Sapphire from Montana

If you are searching for a centerpiece that will end your search for the perfect engagement ring or that rare natural treasure for a collector, this Montana sapphire from The Natural Sapphire Company answers that call. This beautiful transparent 1.80 carat oval sapphire measures 7.26 x 6.02 x 4.94 mm, and it has a mixed brilliant cut that brings both depth and lively scintillation. The clarity grade is very slightly included, evaluated at eye level, so the stone looks clean and bright to the naked eye while retaining natural character that collectors prize. The color reads as a greenish blue with medium intense saturation, a tone that is both distinctive and versatile, and the polish is excellent which ensures crisp reflections and a smooth, satiny surface. Importantly this gem has received no enhancement, making it a rare untreated example of Montana origin, a provenance that carries a reputation for unique teal and blue green hues, and a story that appeals to anyone who values natural beauty and traceable sourcing.

Imagine this oval sitting at the heart of a ring, pendant, or pair of earrings, where its mixed brilliant faceting and superb polish will play with light in ways that feel dynamic and intimate. The medium intense greenish blue will show different facets of its personality depending on metal, setting, and surrounding stones, moving from cool deep teal under soft indoor light to a brighter, more oceanic blue when held toward the sun. The proportions, with a table and depth balanced by the 4.94 mm height, allow the stone to sit eloquently in low profile bezel settings or to command attention from a four prong solitaire, and the 7.26 x 6.02 mm oval footprint wears comfortably as a daily ring center or as a focal point in an elegant pendant. Because the clarity is very slightly included only on close inspection, the gem maintains both durability and eye appeal, so it can be chosen with confidence for an engagement ring that will be worn every day, or treasured as an exhibit piece in a collector cabinet.

For custom design pairing ideas that elevate the greenish blue heart, consider a halo of small brilliant white diamonds set in platinum to create a crisp, modern contrast, the cold white metal and diamonds amplifying the jewel tone and increasing apparent size and sparkle. If you desire warmth and romance, a rose gold setting with a halo of pink sapphires will draw out the green undertones and give an antique inspired glow. For a more architectural look, flank the oval with tapered baguette diamonds in a three stone composition, these linear accents will lengthen the profile and focus attention on the sapphire, and a platinum or white gold band with pavé diamonds will add sustained brilliance without overpowering the center. For collectors and lovers of color, pair the Montana sapphire with mint green or teal sapphires to form an elegant tonal gradient, or use vivid green tsavorite garnets or classic emeralds to emphasize the gem s greener character for a bolder color statement. Champagne diamonds or warm yellow gold settings will bring out subtle warm notes in the stone, offering a vintage character, while a bezel set pendant or modern bezel ring will protect the stone and showcase the mixed brilliant cut in a minimal silhouette. Consider matching earrings and a pendant that echo the center shape for a coordinated suite, or design a convertible piece that moves from ring to pendant, ensuring the sapphire can be enjoyed in multiple styles. When you are ready to move forward, our gem specialists at The Natural Sapphire Company will guide you through metal choices, accent stones, and exact setting proportions so the final custom piece expresses your taste, flatters the stone, and secures this rare, untreated Montana sapphire for generations to come.
