1.15 Ct. Bluish Green Cabochon Sapphire from Montana

This translucent bluish green sapphire weighs 1.15 carats and is cut into a classical round cabochon, with precise dimensions of 5.46 by 5.56 by 3.47 millimeters. The color reads as light in intensity, offering a soft teal leaning toward bluish green that is characteristic of Montana origin material. Clarity is graded slightly included when evaluated at eye level, which means you will encounter minor internal features that are visible without magnification, yet do not detract from the stone s translucency or overall aesthetic. The cabochon profile has been carefully executed to present an even domed top and a well controlled silhouette, producing uniform color distribution across the crown and maximizing the gem s internal glow. The excellent polish enhances the surface luster, reducing micro abrasion features and allowing the stone s natural color and translucency to read cleanly under varied lighting conditions. Heat treatment has been applied as a standard enhancement to optimize color and remove undesirable brownish tones, and the treatment is stable and permanent under normal wear conditions.

From a lapidary perspective this stone demonstrates refined craftsmanship specific to cabochon cutting of corundum. The cutter aligned the material to minimize the visual impact of internal inclusions and to accentuate the subtle color zoning that gives Montana sapphires their signature appearance. The dome profile is neither overly high nor too shallow, a balance that allows sufficient volume for light scattering without introducing a glassy flat appearance. Attention to symmetry is evident in the near equal length and width measurements, and the 3.47 millimeter depth yields an ideal table to depth proportion for cabochon geometry, preserving both weight retention and structural soundness. Polishing techniques removed undulation across the dome and produced an even satin to vitreous finish depending on viewing angle, which in turn enhances the stone s apparent translucency. Given corundum s refractive index range near 1.76 to 1.77 and its specific gravity around 4.00, this cabochon displays steady light return and a dense feel in hand that communicates quality to experienced buyers.

Durability is a core advantage of this sapphire, making it an excellent candidate for daily wear jewelry. As corundum, sapphire rates nine on the Mohs hardness scale, second only to diamond, and resists scratching from essentially all household materials except diamond and hard abrasives. The cabochon format further improves practical durability because there are no faceted edges to chip, and the rounded dome disperses impact rather than concentrating stress at corners. The 3.47 millimeter depth and well proportioned girdle provide a robust profile that accepts secure mounting options, and the heat treatment applied is a conventional and stable process that does not compromise the crystal structure or long term integrity of the stone. For daily wear I recommend protective settings such as full bezel or flush mounting to shield the girdle and rim, or low profile bezels for rings where the cabochon sits close to the finger. Pronged settings are feasible for pendants and earrings but require careful prong placement to avoid point stress. Cleaning is straightforward, warm soapy water and a soft brush are safe and effective, while steam cleaning and ultrasonic baths should be used with caution when inclusions are present, and routine professional inspection of the setting will ensure the stone remains secure.

As a Montana sapphire supplied by The Natural Sapphire Company this gem carries a provenance that is both sought after and informative for collectors and designers. The light bluish green hue pairs beautifully with both white metals for a cooler presentation and with yellow or rose gold when a warmer contrast is desired, and the modest 1.15 carat weight with its 5.46 by 5.56 millimeter footprint reads larger on the hand than its carat weight might suggest because of the domed cabochon surface. The slight internal characteristics are typical of natural untreated inclusions altered subtly by heat treatment, and they lend identification markers that are often valued by connoisseurs who prioritize natural origin and character. We disclose the heat treatment openly as part of our standard grading and verification, and we can provide guidance for bespoke mounting options that optimize color face up while offering maximum protection. For customers seeking a daily wearable sapphire with natural Montana character, stable enhancement, and meticulous cabochon craftsmanship, this piece from The Natural Sapphire Company is engineered to combine aesthetic nuance with enduring practicality.
