Astra Necklace – Lab-grown diamond – 0.53 carat – Round – 18K yellow gold

A light in motion, delicately placed on the skin.

The Astra necklace reveals an airy composition, made of fine 18K yellow gold chains that overlap lightly.

Punctuated with subtly spaced round laboratory diamonds, it creates a lively, almost dancing play of light.

Neither too discreet nor ostentatious, it adorns the neck with a fluid and contemporary radiance.

Designed to be worn every day as well as to brighten up a dressier outfit, Astra embodies a free, modern and naturally luminous elegance.

Why choose a lab-grown diamond?

The lab-grown diamond invites us to rethink creation

Same brilliance, same hardness, same durability as a natural diamond.

The difference is not visible to the naked eye. It lies in its origin, and in the freedom it allows.

Unlike moissanite or zircon

DIAMELYS lab-grown diamonds retain the very essence of diamond.

Same carbon composition, exceptional hardness, pure and timeless brilliance —
Durability designed to last a lifetime.

Each lab-grown diamond is certified by IGI

Evaluated according to the 4Cs and identified by a unique engraving number, perfectly conforming to its certificate.

Choosing DIAMELYS means choosing an authentic and fully embraced diamond.
