This certified natural blue sapphire parcel is offered with full third-party documentation from Gem Report Antwerp, providing professional gemological verification and strong confidence in authenticity, identification, and disclosure. Officially identified as Natural Corundum – Sapphire, this attractive multi-stone lot is documented under Gemological Report Number 1830015140 AN, dated 24 November 2025, and is accompanied by its original laboratory certificate. The presence of recognized laboratory paperwork adds credibility and traceability that is highly valued by jewelers, designers, collectors, and gemstone buyers.

The parcel consists of eight (8) natural sapphires with a total combined weight of 1.46 carats. Individual stone weights vary from approximately 0.05 ct to 0.41 ct, offering a useful range of sizes for creative flexibility. The stones are cut in a mix of round and oval mixed cuts, a classic and highly marketable combination that balances brilliance, depth, and face-up appeal. Measurements range from approximately 1.94 mm up to 5.05 mm, with depths from 1.94 mm to 4.12 mm, making this parcel ideal for matched layouts, accent stones, or focal designs.

Color is graded Deep to Dark Blue, presenting rich sapphire tones ranging from inky navy to saturated royal blue. These hues are characteristic of sapphires formed in basaltic deposits, which are known for producing bold, darker blue material with strong presence and durability. The stones are described as transparent, allowing light to interact naturally with the internal structure and enhance the depth of color. Natural internal features are visible and consistent with genuine earth-mined sapphire, reinforcing authenticity and natural origin.

The report notes a basaltic deposit origin, an important disclosure for buyers familiar with sapphire geology. As stated on the certificate, it cannot be determined whether these basaltic sapphires have been heated by nature or by man, a standard disclosure for this type of material and fully documented for transparency. This level of honest reporting is essential for informed purchasing and aligns with professional gemstone trade standards.

This Gem Report Antwerp certified sapphire lot is well suited for a wide range of applications, including custom rings, earrings, pendants, bracelets, multi-stone jewelry designs, replacement stones, and resale as certified loose sapphires. The variety of sizes, classic shapes, and deep blue color palette make the parcel especially useful for jewelers and designers seeking natural blue sapphires with documented credentials and consistent visual appeal.

Offered with original laboratory documentation and professional grading, this parcel represents a compelling combination of natural origin, basaltic sapphire character, deep to dark blue color, mixed round and oval cuts, and trusted Gem Report Antwerp certification. It is an excellent opportunity to acquire a versatile sapphire collection with strong usability, authentic documentation, and enduring appeal in the colored gemstone market.
