2.27 Ct. Multi Color Crystal Opal (Jelly Opal) from Australia

This offering from The Natural Gemstone Company is a finely executed Crystal Opal, Jelly Opal, weighing 2.27 carat, presented in an oval outline with measured dimensions of 11.46 by 7.53 by 3.72 mm. The material is described as opaque in its body character, yet it displays strong multi color play across the face, with intense color intensity that reads immediately to the eye. The cutting style is Tablet, a low profile tablet cut that emphasizes a broad table plane and a gently contoured periphery, and the finish is an excellent polish. The origin is Australia, a source renowned for high quality opal material, and the stone has received no enhancement, providing assurance that the optical effects are wholly natural. As a technical proposition, the combination of tablet geometry, precise thickness control, and strong intrinsic color makes this specimen suitable for use as a focal gem in both museum grade collections and high end bespoke jewelry projects.

The tablet cut used for this oval Crystal Opal is a deliberate choice to maximize planar color presentation and to stabilize the play of color across changing viewing angles. The cutter maintained an even thickness of 3.72 mm to balance durability against optical performance, while preserving the elongated oval ratio of approximately 1.52 to one, which creates an elegant silhouette for set work. The cutting process for tablet opals involves careful preforming to align the stone so that the dominant silica layer orientation produces broad flashes rather than fragmented pinfire. Edge control was executed with subtle beveling to produce a clean transition from the broad table to the girdle plane, and the girdle itself is uniformly finished to facilitate secure bezel or low profile claw settings. The excellent polish enhances surface reflectivity and supports unobstructed observation of internal diffraction features, which is crucial when evaluating an opal for collection level placement.

Color grading for this Crystal Opal centers on intensity, distribution, and pattern stability. Technically, the opal exhibits a high intensity grade, showing vivid spectral hues that migrate and reorganize as the stone is moved. The multi color presentation reads as a combination of strong green and blue flashes with complementary secondary hues, and the overall effect is consistent with a high order silica sphere packing that produces distinct diffraction peaks. Pattern morphology leans toward broad patch or flash domains rather than fine pinfire, which is advantageous for visual impact when the stone is mounted flat in a tablet cut. Body tone and transparency are calibrated by the cutter to present the color against a subdued internal field, thereby increasing contrast and visual depth. Clarity characteristics are typical of natural opal, without evidence of laboratory filling or dyeing, and the declaration of no enhancement confirms that the observed brilliance derives from the gem material itself.

From a craftsmanship and collection perspective, this Australian Crystal Opal, Jelly Opal, is engineered to be a centerpiece. The tablet cut along with the oval outline provides a stable platform for high end jewelry design, allowing the cutter to retain optimum color orientation while ensuring a practical thickness for daily wear in rings or pendants. The stability provided by the 3.72 mm thickness and the controlled bevels at the edges make a bezel set particularly appealing for protecting the perimeter of the stone without sacrificing the luminous table. Collectors will appreciate the combination of intense color intensity, precise cutting geometry, and the stone being untreated, which together denote an unaltered specimen suitable for long term investment. The Natural Gemstone Company stands behind the provenance and technical description of this opal, and we invite discerning buyers to evaluate its optical performance in person or under calibrated photography, to validate its role as a defining element in any serious collection or design project.
