Signature Oval Lab-Grown Blue Sapphire Necklace

A classic blue gemstone in an intentionally delicate design, this necklace features an 8 × 6 mm oval lab-grown blue sapphire secured in a polished four-prong claw-prong bezel-style setting. Its deep signature-blue color gives the piece presence while keeping the silhouette refined and easy to wear.

Sapphire is the September birthstone, making this a meaningful option for September birthdays and anniversaries.

Choose sterling silver, 14K yellow gold vermeil, solid 10K white or yellow gold, or solid 14K white or yellow gold. Every option features the same lab-grown blue sapphire and an 18-inch cable chain in the selected metal.

Please Note the Scale

Product photography is enlarged to show the gemstone and setting details. The center stone measures 8 × 6 mm. Including the setting, the finished pendant is approximately 9.1 mm from top to bottom—roughly the size of a fresh blueberry, but with a flatter, elongated oval profile—and about half the diameter of a U.S. dime. It is designed to look delicate on the neckline rather than like a large statement pendant.

Shipping & Availability

Many metal selections may arrive within approximately 3–5 business days. Availability varies and will be confirmed after your order is placed. If you need the necklace by a particular date, contact Matt before ordering so we can confirm the current timeline.

Choosing Your Metal

Sterling silver and 14K yellow gold vermeil offer the same design at a more approachable price. Solid 10K and 14K gold are available in white or yellow gold and have no plated sterling-silver base. The gemstone specifications remain the same across the metal options; choose according to your preferred color, metal composition, care, and budget.
