2.16 Ct. Greyish Blue Sapphire from Montana

This transparent 2.16 carat round greyish blue sapphire from Montana is cut to precise proportions, with dimensions of 7.50 by 7.47 by 4.88 mm, and a calculated depth of approximately 65 percent, a profile that supports good light return without excessive depth loss. The mixed brilliant cut combines a brilliant style crown with a modified pavilion faceting scheme, creating a balance between scintillation and contrast, the crown facets disperse light across the table while the pavilion facets produce strong return and lively sparkle. The stone shows faint color intensity, a subtle greyish blue that is characteristic of Montana material, and it is unenhanced, confirming natural color without heat or diffusion treatments. Clarity is graded as very very slightly included when evaluated at eye level, indicating that inclusions are minimal and do not detract from visual performance under normal viewing, and the excellent polish enhances facet junction definition and surface luster, optimizing both brilliance and durability for setting.

These proportions and the round outline make this sapphire particularly well suited to custom jewellery design, the 7.5 mm diameter and 2.16 carat weight occupy the ideal size range for a solitaire engagement ring center, a pendant, or a prominent halo design, and the round mixed brilliant cutting allows the stone to read larger face up than its carat weight might suggest. For designers seeking to increase perceived saturation, warm metal choices such as 18 carat yellow or rose gold, or a close fitting colored bezel, will visually deepen the faint greyish blue, while a white diamond halo will increase apparent size and provide contrast that emphasizes sparkle. The strong light return from the mixed brilliant faceting makes prong settings an excellent choice to maximize entry light, while a low bezel or semi-bezel offers enhanced protection for everyday wear without sacrificing the clarity and polish that this gem exhibits. At The Natural Sapphire Company we can advise on exact head proportions and prong placement to preserve the pavilion geometry and protect the girdle, ensuring optimal performance in any bespoke mounting.
