0.75 Ct. Bluish Green Sapphire from Montana

This gem is a transparent 0.75 carat bluish green sapphire, presented in a fancy shape with precise measurements of 5.77 by 5.26 by 3.49 mm, and an evaluated depth of approximately 63 percent relative to the average diameter. The cut is a fancy cut that balances visual appeal with practical proportions, and the polish is graded excellent, producing clean facet junctions and crisp light return. Clarity is graded slightly included, evaluated at eye level, which means the stone maintains strong transparency while displaying natural internal features that are consistent with origin and formation. The color intensity is described as intense, and the hue is a clear bluish green that reacts vibrantly to both natural and artificial light. The sapphire has been heat treated for enhancement, a stable and commonly applied process in gem finishing, and the stone is sourced from Montana, a well documented and historically significant origin for fine sapphires.

The dimensions and weight of this sapphire make it particularly suited to custom jewelry projects that demand a center gem which is both visually prominent and versatile in setting. At 0.75 carat and just under 6 mm in its longest dimension, the gem is large enough to serve as a solitaire center in a refined engagement ring, yet compact enough to be set as a focal accent in three stone rings, pendants, or earrings where symmetry and balance are important. The fancy shape offers designers the freedom to orient the gem in multiple ways, and the near 63 percent depth percentage indicates well considered proportions that support stable light performance without excessive bulk. These attributes allow for a wide range of design approaches from modern minimal bezels to intricate milgrain or halo treatments, and the stone will sit comfortably within common mounting templates while still offering room for custom bezel walls and prong designs.

Clarity and polish are important considerations for custom settings, and this sapphire responds well to deliberate design choices. The slightly included clarity grade means that inclusions are present at eye level, but they are not so prominent as to compromise the stone integrity or to prevent attractive light return. In practice this allows jewelers to place the gem so that inclusions are minimized visually, for example by orienting the stone to place a larger inclusion beneath a prong or in a less visible sector of a pendant. The excellent polish enhances surface brilliance and reduces the need for aggressive cleaning after setting, and it allows the intense bluish green color to read strongly through the crown. Heat treatment is stable and permanent, and it preserves the stone color while reducing the visibility of some internal features. For customers seeking a clean, vibrant appearance, pairing this stone with complementary metal tones and small accent stones will emphasize the sapphire color and mask minor inclusional characteristics as desired.

Provenance and practical considerations round out the suitability of this piece for custom work. Montana sapphires are recognized for their distinct tonal range and provenance can add traceable character to a commissioned piece, and The Natural Sapphire Company provides documented information about source and treatment to support informed design decisions. The gem size and profile are compatible with common jewelry weights and finger sizes while allowing bespoke proportions for unusual or heirloom mountings. For custom settings, precise measurements of 5.77 by 5.26 by 3.49 mm enable accurate CAD modeling and wax carving, and the approximately 63 percent depth assists in predicting overall reveal and bezel wall height. Taken together the weight, shape, clarity, color intensity, polish, treatment, and origin make this sapphire a highly adaptable choice for custom jewelry, and The Natural Sapphire Company can provide additional grading details and mounting recommendations to ensure the final design showcases the stone to best effect.
