0.35 Ct. Greenish Blue Sapphire from Montana

This transparent 0.35 carat pear shape greenish blue sapphire measures 5.45 x 3.60 x 2.46 mm and is presented with a mixed brilliant cut that maximizes sparkle and scintillation. The stone displays an intense color intensity that reads as a vivid teal leaning toward blue, a hue that is particularly prized by collectors and connoisseurs. Clarity is graded as very slightly included, evaluated at eye level, meaning that the inclusions are minimal and do not detract from the overall transparency or face up appearance under normal viewing. The polish is excellent, producing crisp facet junctions and lively light return. This sapphire has been heat treated, a common and stable enhancement that improves color saturation and uniformity without compromising the integrity of the material when properly disclosed. The Natural Sapphire Company presents this gem with full disclosure of its attributes and a clear photograph of the stone, allowing an informed assessment of its face up color and proportions.

From a gemological perspective, each attribute of this sapphire contributes to its desirability and value in ways that matter to an educated buyer. Carat weight is modest at 0.35 carat, yet the pear shape and careful cutting give a larger face up presence relative to its weight, making it well suited for delicate rings and pendants where symmetry and profile are important. The mixed brilliant cut uses a combination of brilliant style facets on the crown and proportioned pavilion facets to balance fire and brilliance with a pleasing outline, which is especially effective in elongating the pear shape and directing light through the gem. Clarity described as very slightly included, evaluated at eye level, indicates the stone is essentially eye clean to most viewers, with inclusions that are small and well positioned so as not to interrupt the visual flow. Intense color intensity is a primary value driver for sapphires, and this specimen shows saturated hue with good tone, the combination of which yields strong face up appeal. Excellent polish enhances luster and maximizes optical performance, which is a subtle but meaningful factor for buyers who appreciate workmanship and finish.

The origin of this sapphire in Montana adds an important dimension to its story and market value. Montana sapphires are renowned for producing a distinct range of blue and greenish blue tones that are often described as cool, clear, and slightly teal in character, a result of specific trace element chemistry and the unique pegmatitic and alluvial deposits of the region. Montana sources historically yield stones with fine clarity and interesting pastel to medium saturated hues, and market interest in Montana provenance has grown because of the combination of color character and geological rarity relative to larger global deposits. For collectors and buyers who prioritize origin as part of value, a Montana attribution signals a specific aesthetic and a geological provenance that is verifiable through consistent color and inclusion patterns. Heat treatment is commonly applied to Montana sapphires to gently enhance blue and teal tones, and when fully disclosed it is an accepted and stable enhancement in the trade. The Natural Sapphire Company maintains transparent sourcing and disclosure practices, and this stone is offered with clear information about origin, treatment, and cutting. For a buyer seeking a refined, eye pleasing greenish blue sapphire with excellent polish, a well executed mixed brilliant pear outline, and the noteworthy provenance of Montana, this 0.35 carat gem represents a thoughtful and technically sound choice for a bespoke engagement ring, an elegant pendant, or a collector grade cabinet.
