23.50 Ct. Lapis

This specimen is a 23.50 carat oval lapis, dimensions 24.69 x 19.02 x 6.00 millimeters, executed in a tablet cut that emphasizes planar symmetry and surface continuity. The tablet cut employed here is a low domed cabochonal style where the crown is deliberately flattened to create a broad table plane, this approach maximizes the perception of uniform color across the stone and reduces light scattering that can reveal internal heterogeneities. The proportions are carefully controlled to maintain even thickness and edge flow, the 6.00 millimeter depth providing sufficient material to produce a stable setting margin while preserving a pleasing face up profile for rings and pendants. The finish quality is excellent, the polish achieving a high specular reflection that enhances the lapis blue when viewed under directional illumination, and the oval outline is well centered with smooth girdle transitions that indicate attentive lapidary control and minimal post cutting reworking.

Color characteristics are a primary determinant of lapis valuation, and this example exhibits a vivid color intensity with a strong primary blue hue, high saturation and a medium to deep tone that reads as pure royal to ultramarine blue in controlled daylight. The piece appears to have minimal diffuse lightness from calcite matrix, and the fine distribution of accessory pyrite specks imparts a subtle metallic contrast without dominating the visual field, this balance is desirable in higher quality lapis because it preserves chromatic purity while adding natural character. Lapis is a rock composed chiefly of the mineral lazurite with variable proportions of calcite and pyrite, and the visual interplay of these components drives both aesthetic appeal and market classification, the low visibility of white calcite here and the restrained pyrite presence place this stone within the upper tier of untreated lapis material. Enhancement status is no enhancement, this untreated condition is significant because many lower grade lapis pieces are dyed or stabilized to mask calcite or to intensify blue, absence of such treatments confirms that the observed vivid color and surface stability are intrinsic to the material, this supports long term color permanence and reduces concerns about fading or surface degradation when set into jewelry.

Provenance and origin contribute materially to perceived and recorded value because certain localities are historically associated with particular quality signatures and limited supply, however the origin of this lapis is Unknown, and that uncertainty must be considered alongside the gemological attributes when assessing value. Well documented Afghan lapis from the Sar e Sang deposits is often priced at a premium due to its long association with deep ultramarine hues and historical significance, Chilean lapis tends to present a slightly lighter tone with different textural characteristics, and Russian material can show distinct accessory mineral patterns. When origin is unknown, buyers evaluate the piece primarily on measurable parameters, specifically weight, dimensions, color grade, absence of enhancement, and craftsmanship quality, this individual stone scores strongly across those criteria which supports a collector and designer interest irrespective of proven provenance. At The Natural Gemstone Company we prioritize transparent reporting, and while we cannot assign a specific mine for this specimen, we document physical and treatment information rigorously and provide recommendations for setting and conservation. The robust 24.69 x 19.02 millimeter tablet lends itself to secure bezel mounting or low profile collet settings that protect the tablet edges and showcase the broad table of color, the considerable face area and vivid chroma make this an ideal centerpiece for a statement ring or pendant, and the untreated nature ensures the color will remain consistent through routine wear.
