0.35 Ct. Bluish Green Sapphire from Montana

This transparent 0.35 carat bluish green sapphire from Montana, presented by The Natural Sapphire Company, is fashioned in a classical emerald cut measuring 5.10 by 3.00 by 2.21 millimeters. The cutting style employs parallel step facets on the crown and pavilion with truncated corners and a broad rectangular table, producing long, mirrorlike facet planes that emphasize color and internal clarity rather than fine scintillation. The gem is graded very slightly included when evaluated at eye level, and this clarity grade, combined with excellent polish, allows the step facets to deliver crisp internal reflections and distinct facet outlines. The medium intense color intensity is well balanced across the table and facets, revealing a bluish green hue that results from iron and titanium chromophores common to Montana material. The stone has been heat treated to stabilize and enhance saturation, a standard and stable enhancement for sapphire that refines tonality and often reduces silk without compromising structural integrity. The pavilion depth, approximately forty three percent relative to length, and the controlled facet geometry yield consistent light return and a pronounced hall of mirrors effect.

In comparative terms this emerald cut sapphire behaves differently from more commonly seen brilliant or mixed cuts. Compared with brilliant cut sapphires, which use multiple small facets to generate dispersed scintillation and frequent pinpoint flashes, this step cut produces larger, broader flashes and a more architectural, directional reflection pattern, making the viewer more aware of hue and clarity than of sparkle frequency. Versus emeralds and beryl family stones, sapphire benefits from a higher refractive index, approximately 1.76 versus roughly 1.58 for emerald, which translates into stronger surface luster and more intense internal contrast under similar faceting. Compared to other Montana sapphires that can present lighter or more pastel tones, this specimen’s medium intense saturation gives deeper facet-to-facet contrast without appearing overly dark in smaller ring settings. The combination of excellent polish and precise step faceting accentuates the gem’s bluish green pleochroism as you rotate it, producing alternating green and blue flashes that are more restrained and refined than the high scintillation associated with brilliant cuts. This sapphire is well suited for a refined, geometric setting where the cutting artistry and Montana provenance will be showcased, and it exemplifies the measured light behavior and color control that collectors and connoisseurs value from The Natural Sapphire Company.
