1.79 Ct. Bluish Green Sapphire from Montana

This offering from The Natural Sapphire Company is a transparent bluish green round sapphire weighing 1.79 carats, with dimensions 6.59 x 6.64 x 5.03 mm. The gem is fashioned in a mixed brilliant cut, and it exhibits a medium color intensity and an excellent polish. Clarity is graded slightly included at eye level, indicating minor internal features that do not detract from the gem s overall transparency and do not compromise its structural integrity. The exact carat weight is a primary determinant of this stone s market position, the 1.79 carat weight places the sapphire well above common parcels of smaller Montana material, and it commands attention for both visual presence and rarity given the limited supply of larger, fine quality stones from that origin. The mixed brilliant cut optimizes light return within the constraints of the stone s proportions, and the excellent polish ensures that facets interact cleanly with light, enhancing perceived size and sparkle relative to stones of similar millimeter dimensions.

Natural, untreated origin is an important contributor to value, this sapphire has no enhancement, and that natural state is increasingly prized among collectors and discerning buyers, especially for material from Montana, a region noted for distinctive aqua to bluish green hues and for producing stones with character and provenance. The combination of a substantial 1.79 carat weight, precise dimensions, a well executed mixed brilliant cut, and a no enhancement declaration provides a balanced profile of aesthetic appeal and rarity. Slight inclusions are typical for natural Montana sapphires, they are consistent with the gem s transparency and do not impede its suitability for daily wear, especially when set with appropriate protective settings. For those assessing this sapphire from both a gemological and practical standpoint, the measured weight elevates its significance relative to smaller stones, it influences per carat value, and it enhances the stone s potential as a center gem for a bespoke ring or as a collectible piece within a carefully curated collection. The Natural Sapphire Company provides these specifications to support informed decisions, and this Montana sapphire represents a notable example of natural weight driven rarity combined with attractive optical performance.
