1.64 Ct. Greenish Blue Sapphire from Montana

From the glacial hills of Montana where pockets of sapphire form over millions of years, this gem began its story in cold alpine gravels and river beds, miners and prospectors carefully recovered a rough crystal that would later become a jewel. At The Natural Sapphire Company we trace each stone to its origin, and this greenish blue sapphire carries the quiet character of Montana fields, a landscape of sky and sage, provenance that adds depth to every facet. Heat treatment was applied to enhance the intrinsic hue, a standard and stable technique that brings out the vivid color intensity while preserving natural character, this process is transparent to our gemologists and celebrated by collectors.

The sapphire itself weighs 1.64 carat, with a cushion shape and dimensions of 7.44 x 6.26 x 4.57 mm, cut in a mixed brilliant style to balance sparkle and color, clarity is graded very slightly included at eye level, giving a gem that is beautifully transparent with small natural features that confirm its authenticity, the polish is excellent and the mixed cut promotes lively reflections across the table and crown. The greenish blue tone shifts subtly as light moves, presenting deeper blue in shadowed angles and brighter teal flashes under direct light, the cushion silhouette feels classic and versatile, the size is ideal for a single center stone in a ring or as a focal point in a pendant.

This sapphire adapts easily to custom design choices, set it in a simple four prong solitaire to showcase the color, choose a halo of fine diamonds to add contrast and apparent size, ask for a low bezel for daily wear, or a high cathedral setting for dramatic light return, pair it with warm rose gold to emphasize green undertones, or cool platinum to enhance blue depth, consider custom three stone combinations, vintage filigree details, split shank bands, bezel halo pendants, or matched stud earrings for a coordinated set. Our design team at The Natural Sapphire Company will work with you to choose metal, setting style, and accent stones that complement the vivid color intensity and cushion proportions, each commission becomes a continuation of its Montana origin, crafted into a personal heirloom.
