This matched pair of natural blue sapphires is offered with full third-party documentation from Gem Report Antwerp, providing professional gemological verification and strong buyer confidence. Identified as Natural Corundum – Sapphire, this pair is accompanied by Gemological Report No. 1830015141 AN, dated 24 November 2025, confirming authenticity, identity, and grading details. Presented sealed and matched to its original laboratory paperwork, this sapphire pair is ideal for fine jewelry production, collector acquisition, or high-end custom design.
The pair has a total combined weight of 1.06 carats, with each sapphire weighing 0.53 carat, making them exceptionally well suited for matched sapphire earrings, toi et moi rings, luxury stud earrings, or balanced multi-stone jewelry designs. Both stones are precision fashioned in a pear mixed cut, a classic and elegant shape prized for its graceful silhouette, excellent face-up presence, and ability to showcase depth of color. The pear mixed cut combines brilliant and step-cut facets, enhancing light return while preserving the richness of natural sapphire coloration.
Color is graded Deep Blue, displaying saturated royal blue to inky blue tones that are highly sought after in the sapphire market. The stones are described as transparent, allowing light to interact naturally with internal features characteristic of genuine earth-mined sapphires. Measurements are well matched, with dimensions of approximately 6.02 × 4.10 × 2.49 mm and 6.05 × 4.02 × 2.60 mm, reflecting careful selection and cutting consistency—an important factor for jewelers and designers seeking symmetry and visual harmony.
The report notes indications of heating present, a common and widely accepted enhancement within the sapphire trade that improves color and clarity stability while maintaining natural origin. This disclosure is fully documented on the Gem Report Antwerp certificate, ensuring complete transparency and compliance with professional gemstone disclosure standards. Heated natural sapphires remain dominant in fine jewelry and are highly valued for their durability, color consistency, and long-term wearability.
