This certified natural blue sapphire parcel is accompanied by an official Gem Report Antwerp gemological report, offering strong third-party validation and immediate market credibility. The collection consists of seven (7) natural corundum sapphires with a total combined weight of 1.82 carats, precision fashioned in oval mixed cuts to maximize brilliance and depth. Color is graded deep to dark blue, displaying rich inky sapphire tones with natural internal characteristics consistent with genuine earth-mined material. Transparency is noted as transparent, with visible inclusions typical of natural sapphire and prized by collectors seeking authenticity over synthetic perfection.

According to the report, the stones originate from a basaltic deposit, a geological source known for producing bold, saturated blue sapphires favored in both fine jewelry and investment parcels. Individual stone weights range from approximately 0.15 ct to 0.55 ct, with measurements spanning 3.53–5.80 mm in length and 2.50–4.01 mm in depth, making this parcel ideal for custom rings, matched multi-stone jewelry, earrings, or resale as certified loose sapphires. The oval mixed cut profile enhances face-up presence while maintaining classic market appeal.

The accompanying Gem Report Antwerp certificate (Report No. 1830015139 AN, dated 24 November 2025) confirms identification as Natural Corundum – Sapphire. Heat treatment status is stated as undetermined, which is standard for basaltic sapphires and fully disclosed on the report—an important factor for transparency-driven buyers. Presented sealed in a tamper-evident gem case, this sapphire lot is well-suited for collectors, jewelers, designers, and gemstone investors seeking certified natural blue sapphires, deep blue sapphire parcels, oval cut sapphires, and Gem Report Antwerp certified gemstones with strong resale and design versatility.
