Description from the seller
Certified parcel of natural corundum sapphires presented in a sealed Gem Report Antwerp holder accompanied by a full laboratory report dated 24 November 2025 under report number 18050135AN. This curated selection contains twenty-two transparent stones, each individually graded and listed with measurements from 2.05 to 3.88 x 2.65 to 4.00 mm. Total combined carat weight recorded as 4.55 ct. Shapes include round, oval, and pear in mixed cuts, offering a balanced assortment suited for fine jewelry creation, calibrated layout sets, and gemstone collection portfolios focused on natural blue-green sapphire variation. The color spectrum ranges from light greenish blue to deep greenish blue, with several stones displaying subtle bi-color transitions characteristic of naturally occurring corundum.
The accompanying certificate notes indications of heating, an accepted enhancement method widely used in the sapphire trade to refine clarity and deepen chromatic saturation. Transparency is rated as transparent, making these stones suited for precision settings, multi-stone compositions, and high-quality artisan jewelry frameworks. The range of tones within the lot creates opportunities for matched pairs, gradient designs, or multi-gemstone arrangements that highlight the organic palette of green-blue corundum sourced for both aesthetic harmony and visual contrast.
Gem Report Antwerp’s documentation provides authentication, confirms natural origin, and supports traceability for collectors, resellers, jewelers, and investors seeking certified gemstones with measurable grading results. This parcel offers versatility for designers producing contemporary sapphire pieces, such as cluster rings, eternity bands, custom earrings, or color-themed pendants. The selection is also suited for gemstone traders assembling inventory with reliable certification and consistent calibrations across a diverse palette of blue-green hues.
Appealing to enthusiasts of natural corundum, the lot balances transparency, varied cutting styles, and a broad tonal range, making it a strong choice for buyers seeking lab-documented sapphire parcels with both collectible and design-ready potential.
