What's New at Gray and Sons This Week

Featured New Arrivals

AGL Certified Sapphire and Diamond Ring in 14k White Gold

For those with a passion for sapphire jewelry, this AGL-certified sapphire ring represents a rare find in today's estate jewelry market. The center stone is an extraordinary natural sapphire weighing approximately 3.13 carats (measuring 7.29 × 7.22 × 6.16 mm), exhibiting a captivating blue-violet hue that commands attention.

What makes this piece particularly remarkable is its AGL certification confirming the sapphire is completely natural and untreated—no heat enhancement whatsoever. In an era where treated gemstones dominate the market, finding an untreated sapphire of this caliber is increasingly uncommon. The center stone is beautifully complemented by round brilliant-cut diamonds totaling approximately 0.81 carats (G-H color, SI2 clarity), all set in lustrous 14k white gold. Currently sized at 7, this exquisite ring is offered at $8,800, representing exceptional value against its $12,000 retail price.

This particular example in warm 18k rose gold features 32 brilliant-cut diamonds totaling approximately 0.58 carats, adding a touch of sparkle to the already striking silhouette.

What sets this piece apart is its impeccable provenance and condition.

Size 19 accommodates most wrist sizes comfortably. Priced at $13,500 compared to the $15,000 retail value, this represents an excellent opportunity to acquire an iconic Cartier design with complete documentation.
