5.20 Ct. Lapis from Afghanistan

This 5.20 carat cushion shaped blue lapis is a standout example of natural material, offered by The Natural Gemstone Company, with dimensions 17.11 by 15.07 by 1.81 millimeters, a tablet cutting style, and an excellent polish. The cabochon like tablet cut creates a low profile, broad face that emphasizes color uniformity and surface quality, making the piece ideal for modern minimalist jewelry or refined inlay work. This lapis is opaque, untreated, and unenhanced, which is an important factor for collectors and connoisseurs who prioritize natural state and provenance. Origin is Afghanistan, a source historically associated with the finest quality lapis lazuli, and this specimen demonstrates the deep, saturated blue tone that distinguishes high end Afghan material from more common commercial sources. The combination of substantial face size, weight of 5.20 carats for lapis, and the exceptional color distribution on a tablet cut makes this stone notably rare when compared with the more frequently encountered smaller or less evenly colored pieces.

When assessing lapis lazuli, trained buyers focus primarily on color, the presence or absence of calcite and pyrite inclusions, overall texture and polish, and any evidence of enhancement or dye. Color is the principal determinant of value, with rich, even ultramarine to royal blue tones commanding the highest prices, and paler, streaked, or mottled material being less desirable. Calcite appears as white veining or cloudiness and lowers apparent richness, while pyrite appears as metallic specks that can either enhance the stone with a desirable glitter or detract if excessive and uneven. This particular lapis is characterized by a dense, uniform blue field with minimal visible calcite, and only minor, well distributed flecks of metallic character if present, a combination that supports a premium grade. The tablet cut and excellent polish preserve the natural surface texture while providing a sleek, refined appearance, and the shallow 1.81 millimeter thickness is intentionally preserved to maximize the face area without compromising the stone integrity. From a gemological standpoint, the lack of enhancements is especially significant, because heat treatment, dyeing, or resins are sometimes used in lower grade material to mask calcite or to intensify color, practices that materially affect long term value and desirability for educated buyers. This piece’s natural state, coupled with Afghan provenance, places it within a small subset of lapis specimens that are sought after by collectors, designers, and investors.

For the informed buyer, the appeal of this lapis extends beyond immediate aesthetics to considerations of rarity, versatility, and long term preservation. A 5.20 carat tablet cut lapis measuring 17.11 by 15.07 millimeters offers a large, continuous face that is uncommon in high quality, uniformly colored material, because larger slabs of pure, calcite free, richly colored lapis are geologically less common and more likely to be broken into smaller pieces during extraction and cutting. The tablet cut here is particularly well suited to bezel settings, low profile pendants, cufflinks, and inlay applications where a flat, expansive blue field is desired, and the subdued thickness makes the stone ideal for contemporary jewelry that emphasizes clean lines. Buyers should factor in lapis hardness in the Mohs range of approximately 5 to 5.5, and plan protective settings and occasional maintenance to preserve the surface polish, avoiding harsh chemicals, ultrasonic cleaning, and prolonged exposure to heat or acids. For collectors and designers who value transparency of origin and natural condition, this stone is compelling, because Afghan lapis of this size and uniformity is scarce in the market, and pieces of comparable face area and color saturation often command premiums due to their limited supply.

The Natural Gemstone Company stands behind the documented origin and natural condition of this lapis, and can provide additional details on provenance, handling recommendations, and suitable setting suggestions to assist specialists and private collectors in making an informed acquisition. For those assessing investment potential, the combination of authentic Afghan origin, unenhanced condition, exceptional polish, and an unusually large tablet face contributes to both immediate desirability and enduring collector interest. Whether intended for a bespoke commission or to enhance a curated collection, this cushion shaped, tablet cut blue lapis represents a rare meeting of size, color, and natural integrity, and it is presented with the clear, factual description that discerning buyers require when comparing alternative options.
