Estate 18K Y Gold 172.30ctw Agate & Aquamarine & 0.33ctw Diamond Necklace

From our Estate Collection, a breathtaking neoclassical revival necklace blending artistry and elegance in every detail.
This substantial statement piece centers on a masterfully carved natural green and white chalcedony cameo, portraying a noble lady in profile. Set in 18K yellow gold, the floral-leaf motif mounting evokes an opulent romanticism, accented by sixteen bead-set round brilliant diamonds (0.33ctw, F–G color, SI1–SI2 clarity), shimmering from the hand-fabricated golden endcaps.

The pendant is suspended from four strands of over seven hundred eighty natural aquamarine beads, beautifully hand-strung in graduated tone and size. The aquamarines are lightly greenish-blue with a soft glow, treated for clarity and brilliance, totaling 172.30ct. This necklace closes with an engraved 18K gold box clasp, complementing its luxurious weight and vintage styling. Handmade in Italy, this one-of-a-kind piece is hallmarked from the province of Ancona (registry number 775).

A rare and wearable heirloom for the collector of grand romantic jewels, vintage Italian craftsmanship, or fine cameos with museum-worthy presence.
