3.20 Ct. Greenish Blue Sapphire from Montana

One beautiful transparent 3.20 carat oval shape greenish blue sapphire, measuring 9.39 by 7.54 by 5.79 mm, offers a rare combination of color, size, and cut that stands apart from typical market offerings, The Natural Sapphire Company presents this Montana origin gem with pride, its medium intense color capturing a balanced greenish blue tone that reads as both modern and timeless, the oval silhouette flatters while maximizing perceived size, and the mixed brilliant cut gives it an optical performance that outperforms many standard cuts available at the same price point. Whereas many commercial sapphires on the market can appear flat, overly dark, or oddly windowed, this stone remains transparent and lively, its very slightly included clarity grade at eye level meaning it appears clean to the naked eye while retaining natural character that many collectors and connoisseurs prefer. The excellent polish elevates the overall presentation, delivering crisp facet junctions and a bright surface that immediately communicates quality, the enhancement by heat treatment is a widely accepted industry practice that stabilizes and enriches the stone without masking its natural Montana provenance.

The mixed brilliant cut is the defining feature that most directly enhances this sapphires ability to reflect light and exhibit both brilliance and color, by combining a brilliant facet pattern on the crown with a carefully calculated pavilion configuration the cutter has engineered multiple paths for light to enter and return, broad flashes of light across the oval surface provide a pleasing, even brightness, while smaller scintillating facets deliver lively pinpoints of sparkle as the stone moves. Compared to simple step cuts that emphasize depth and color at the expense of scintillation, or to basic full brilliants that can sometimes sacrifice color saturation for sheer sparkle, the mixed brilliant approach achieves a refined balance, keeping color distribution even across the table and reducing windowing where a shallow or poorly proportioned oval would allow light to escape through the bottom. The pavilion depth of 5.79 mm and the overall proportions were chosen to maximize internal reflection for this particular refractive index and color saturation, so the greenish blue tone is seen as a deep, even field when viewed face up, yet the stone still responds to motion with lively flashes, a quality that places it ahead of many off the shelf options that either look dead under indoor lighting or overly saturated under sunlight.

From a value and practical perspective this sapphire stands out for its combination of natural origin, attractive size, and superior cutting and finishing, the very slightly included clarity grade provides reassurance that this is a natural, untreated by filling gem, while the heat treatment used is stable and common in fine sapphires, enhancing the overall color without compromising structural integrity. The excellent polish and thoughtful mixed brilliant facet design improve the apparent clarity and color, meaning a buyer gains the visual impact of a more costly stone without having to pay a premium price for unnecessary weight or for risky treatments commonly found on the lower end of the market. In a setting this oval 3.20 carat greenish blue Montana sapphire will translate into a strong center stone presence, sitting elegantly on the finger or as a pendant, and its versatile medium intense color will harmonize with white, yellow, or rose metal mountings while offering distinctiveness when compared to the typical blue sapphires that dominate the market. At The Natural Sapphire Company we pride ourselves on sourcing and presenting gemstones that combine honest disclosure with refined cutting, and this Montana mixed brilliant oval offers a superior balance of beauty, performance, and value for buyers who want a unique, wearable, and visually compelling sapphire.
