6.76 Ct. Boulder Opal from Australia

This 6.76 carat oval Boulder Opal from Australia is presented by The Natural Gemstone Company, featuring precise dimensions of 22.00 x 8.50 x 3.98 mm, a tablet cut profile, translucent body, and multi color play that exhibits intense color intensity. The cutting style is a low domed tablet, executed to preserve the thin opal color layer while delivering a uniform oval outline and an even surface, the polish grade is excellent which allows for minimal light scatter and maximum color flash, the clarity is graded eye clean at eye level which indicates an absence of visible inclusions or matrix interruptions across the face, and no enhancement has been applied to this piece ensuring that the opal is in its natural state.

From a gemological and setting perspective this boulder opal demonstrates a broad scatter of spectral colors across a pale translucent ground, the tablet cut emphasizes surface oriented play of color which is strongest when the stone is oriented perpendicular to the incident light, the thin 3.98 mm thickness balances wearable low profile design with sufficient depth to secure in bezel or inlay settings, and the oval outline at 22.00 x 8.50 mm is ideal for elongated designs such as pendants and bar style rings where the color pattern can be fully appreciated. As a Boulder Opal there is typically preserved ironstone matrix on the pavilion or back which contributes to structural stability and assists lapidary control during cutting, the cutter has prioritized retention of the color bar while achieving an eye clean table, this specimen benefits from subdued anatomy that responds strongly to diffused lighting and directional spot lighting for the most pronounced play of color. Handling and care guidelines are standard for opal, avoid rapid temperature changes, extended exposure to solvents, ultrasonic cleaning, and steam, secure with bezel mounting when possible to protect the thin edge, and for advisory inspection and bespoke setting recommendations contact The Natural Gemstone Company for mounting options, provenance documentation, and custom jewelry services.
