0.44 Ct. Greenish Blue Sapphire from Montana

This pear shape greenish blue sapphire weighs 0.44 carat and measures 5.93 x 4.02 x 2.69 mm, the gem is transparent and has been cut to a mixed brilliant style that balances faceted crown brilliance with a faceted pavilion for efficient light return, clarity is graded as very slightly included when evaluated at eye level, color displays a medium light intensity that carries cool blue with subtle green overtones, and the surface finish is listed as excellent polish, the stone has been heat treated to optimize color and stability, origin is Montana, and the gem is offered by The Natural Sapphire Company.

Optically the mixed brilliant configuration enhances scintillation and overall brightness, the crown facet arrangement produces numerous small flashes of light that animate the table when the stone moves, the pavilion facets contribute to controlled light return so the gem reads as lively for its size, medium light color intensity allows more internal reflection than deeper tones which can absorb light, the very slightly included clarity at face up means inclusions have minimal impact on light performance under normal viewing conditions, excellent polish preserves crisp facet junctions which is critical for maximizing mirror like reflections and maintaining consistent contrast across the face of the stone, the result is a gem that exhibits a delicate balance of sparkle and transparent clarity that suits refined, understated jewelry designs.

When compared with other gemstones in its category, this Montana greenish blue sapphire presents a distinct reflective profile, corundum variants typically show a vitreous luster and a refractive index around the high mid range for common gem materials, this gives sapphires stronger brilliance and sharper facet reflections than beryl varieties such as aquamarine, aquamarine typically has a lower refractive index and consequently a softer, more glassy return of light, spinel and topaz also tend to show less intense facet contrast than corundum because their refractive indices are lower, within the sapphire family there are notable differences, Sri Lankan sapphires often show bright, lively reflection with clear, saturated blues, Kashmir stones are prized for a velvety depth that can diffuse reflections in a pleasing way but may read less sparkly in direct light, Australian and Madagascan sapphires can carry denser tones which increase color saturation at the expense of some brightness, Montana sapphires are frequently lighter and can display unique greenish blue hues, this specimen exemplifies that trend, its medium light intensity allows the mixed brilliant cut to produce crisp flashes that read brighter than many deeper colored sapphires, yet it retains the cool, nuanced tone characteristic of Montana origin.

In practical terms the stone will perform well in settings that allow light to enter the pavilion and circulate, open prong settings and minimal bezels will enhance scintillation and show the full range of its reflective qualities, warmer metal tones may subtly influence the perceived color by reflecting different background light into the gem, the heat treatment reported increases color uniformity and is a stable and commonly used enhancement in sapphires, routine care includes avoiding harsh chemicals and extreme thermal shock, professional cleaning and inspection will preserve polish and mounting integrity, The Natural Sapphire Company provides detailed imagery and measurements to assist with selection, and we can advise on setting options that best complement the stone s reflective behavior and tonal character.
