2.26 Ct. Crystal/Jelly Opal from Australia

This translucent 2.26 carat oval Crystal, Jelly Opal from Australia presents as a refined study in optical purity and skilled lapidary execution, ideal for the discerning collector. Measuring 10.34 x 8.32 x 4.11 millimeters, the stone has been fashioned in a tablet cut, a flattened, low profile outline with carefully controlled thickness to maximize internal transmission of light while preserving a broad surface area for play of color. As a Crystal or Jelly Opal this example displays notable translucency rather than the opaque body typical of white opal types, allowing interaction between incident light and the regular silica sphere microstructure responsible for diffraction based play of color. The tablet cut accentuates this characteristic by minimizing surface curvature and reducing the scattering that can mask delicate color flash, resulting in clean, easily viewed spectral effects across the oval surface when illuminated. Origin and natural state are significant to connoisseurs, and this specimen is Australian in origin and unenhanced, supplied in its natural, untreated condition by The Natural Gemstone Company.

From a technical grading perspective this opal carries a clarity grade of very slightly included, evaluated at eye level, which indicates that inclusions are present but do not materially distract from the gem while viewed without magnification. The medium color intensity rating describes the strength of the stone s internal color flashes, which are readily observable and balanced across the table without overpowering saturation, making it versatile for both subtle and more expressive settings. The polish has been evaluated as excellent, denoting a lapidary finish free from polish pits and with surface sheen optimized to maximize light entry and spectral return. The tablet cut itself is a deliberate craftsmanship choice, requiring precise control of thickness and table flatness to avoid lopsided diffraction patterns, and to sustain the structural integrity of a relatively soft material. Opal s physical properties, including a refractive index range typical for opal and a tendency to contain variable water content at the microscale, mean that lapidary technique must balance thinning for optical transparency against maintaining volume to prevent crazing or fracture during cutting and setting.

For the collector who appreciates nuance in cut and optical behavior, this piece is a technically interesting addition that also functions well in wearable art. The flattened tablet profile enables secure bezel or partial bezel settings that support the stone while leaving the terminal crown surface exposed to incident light, a preferred configuration for maximizing observed play of color. Given opal s moderate Mohs hardness relative to corundum and diamond, careful mounting is advised to protect the stone from abrasion and sharp impacts, and setting designs that shelter the girdle without obstructing the table are recommended. Orientation matters, the tablet cut benefits from face up display under broad spectrum lighting to reveal subtle internal color banding and flashes, while angled accent light will accentuate deeper spectral pockets. Provenance from Australia, absence of enhancement, an excellent polish, and a clarity assessment of very slightly included combine to make this 2.26 carat oval Crystal, Jelly Opal a refined technical specimen, and a worthy focal point for a high end gemstone collection curated by The Natural Gemstone Company.
