2.20 Ct. Blue Cabochon Sapphire from Montana

This translucent 2.20 carat oval blue sapphire measures 7.58 by 6.60 by 4.06 mm, and is finished as a cabochon with a smoothly domed crown and a well defined oval outline. The gem displays intense color intensity with a medium to moderately deep tone, yielding a rich blue saturation that remains vivid through the dome rather than washed out at the edges. Clarity is graded included, evaluated at eye level, and the stone presents characteristic internal features that interact with transmitted light, contributing to a soft internal texture without compromising overall color depth. The surface shows an excellent polish, producing a high degree of vitreous luster across the dome, and the cabochon geometry has been executed to provide an even reflection pattern with a centered apex and symmetrical girdle proportions. This sapphire is heat treated, a standard and stable enhancement used to optimize blue saturation and remove secondary color components, and the provenance is Montana, which informs the expected crystal habit and inclusion suite.

From a lapidary and setting perspective this cabochon demonstrates careful cutting decisions to balance dome height and light transmission, preserving translucency while maximizing perceived color. The cutter appears to have oriented the piece to align the foliation and cleavage planes in a manner that minimizes display of split surfaces, enhancing durability for common jewelry settings. Given the included clarity grade, bezel or hybrid bezel settings are recommended to protect girdle edges and to complement the cabochon form, though a low profile prong mounting can also showcase the dome when secure seatwork is applied. When evaluating for jewelry design, consider the stone for a pendant or statement ring where the domed surface will reveal color shifts under varied lighting, and consult The Natural Sapphire Company for further measurement tolerance, mounting options, and documentation regarding the heat treatment and Montana origin.
