2.10 Ct. Bluish Green Cabochon Sapphire from Montana

This exquisite bluish green sapphire from Montana offered by The Natural Sapphire Company weighs 2.10 carats and presents an elegant oval outline with the measurements 7.14 x 5.88 x 4.53 mm. The gem is cut as a cabochon, a choice that emphasizes its semi translucent character and the depth of its intense color intensity rather than the faceted brilliance associated with faceted sapphires. The cabochon dome and excellent polish allow light to play across the surface to reveal subtle internal color zoning and a velvety sheen that is characteristic of high quality Montana material. At this size and with this color profile, the stone reads as a collector quality specimen ideal for a statement ring, a pendant that centers a refined design, or a bespoke piece where the stone is the primary visual focus. The description you see is consistent with the images and with standard gemological measurement practices, and we at The Natural Sapphire Company are available to provide additional, close up photography and viewing on request.

Clarity is graded as included, evaluated at eye level, which for a cabochon is a typical and often desirable characteristic, as the internal features can add to the gemological story and to the aesthetic texture visible under magnification. Inclusions in Montana sapphires commonly take the form of minute needles, wispy silk, healed fissures, and small crystals, and these features commonly occur in stones that display the distinctive bluish green palette. Included clarity does not necessarily detract from value in this context when the inclusions do not compromise structural stability, and when they contribute to the stone s visual identity. The gem has been heat treated, a stable and widely accepted enhancement for sapphires, used to refine and intensify tone and hue by altering trace element distribution. Heat treatment is a standard practice in the trade and is fully disclosed here to preserve transparency and to inform quality assessment and insurance valuation. The excellent polish indicates careful lapidary work, and the cabochon proportions are designed to retain weight while maximizing surface luster and color saturation.

For the educated buyer the value proposition of this Montana cabochon sapphire is multifaceted. Montana origin carries a strong market niche, prized for its unique teal to bluish green shades and for the geological story that links the gem to alluvial and sub volcanic deposits in a historically important mining region. At 2.10 carats the stone is significant for Montana material, where larger sizes with intense color are less common than in some other sapphire sources. The combination of intense color intensity, semi translucency, and a high quality cabochon finish makes the gem particularly appealing for collectors who prioritize natural character and provenance over pure faceted brilliance. Sapphires are durable for everyday wear, with a Mohs scale value of 9, and a cabochon setting further protects the dome from impact, making bezel settings or low profile bezels practical choices. We recommend routine care with warm soapy water and a soft brush for cleaning, avoiding prolonged exposure to harsh chemicals, and consulting with our mounting specialists at The Natural Sapphire Company for recommendations on metal choices and setting style to best showcase the stone while ensuring security.

When considering purchase, please note that full documentation of origin and treatment can be arranged through independent gemological laboratories at buyer request, and our staff can assist in coordinating a report if desired. The Natural Sapphire Company stands behind the authenticity and disclosed treatment of this sapphire, and we can provide condition reports, high resolution imaging, and custom design consultations to help integrate this gem into a jewelry piece that complements its natural character. For collectors and designers who appreciate the distinct aesthetic of Montana sapphires, this 2.10 carat bluish green cabochon combines geological interest, artisanal lapidary quality, and practical versatility, making it a compelling option for both investment grade collections and for wearable, heirloom quality jewelry.
