Immortal — Alexandrite and Emerald Necklace
A unique jewel born from gemstones of the Romanov era.
IMMORTAL.

The design draws on the ancient symbol of the Ouroboros—the serpent representing eternity, cyclical time and transformation. Here, it is rendered not as a destructive force, but as a guardian: its emerald body encircles the composition, suggesting continuous movement and contained energy.

At its heart rests the 68.57-carat Ural Alexandrite—an object that is not only rare but historically resonant. Comparable stones are no longer mined, and the last significant discoveries date back to the era of the Romanov dynasty.

The Alexandrite is set within an open lotus motif composed of diamonds and emeralds, a symbolic reference to spiritual awakening and the passage from form to essence.

The composition is further complemented by 48 Colombian pear-shaped emeralds. The total weight of all gemstones in the necklace amounts to 226.98 carats.

The object

Three origins.
One singular piece.

Immortal unites three of the world's most coveted gemstone sources in a single work of jewellery. The central alexandrite — from the depleting Ural mines of Russia — displays the stone's legendary colour shift from deep green in daylight to purplish red under incandescent light. Framing it: a carved Russian emerald of 120.34 carats, and 48 Colombian emeralds of Vivid Green saturation.

Each element was individually examined and certified by ICA GemLab in Bangkok (Report #174559, October 2024) — one of the world's leading independent gemological laboratories.

I — The Alexandrite
68.57
Carats · Fancy Polished · 30.38 × 19.25 mm
Among the rarest gemstones on earth. This specimen displays the signature Ural colour shift: deep green under daylight, purplish red under incandescent light — caused by chromium impurities and unique spectral absorption. Hardness: 8.5 Mohs. No treatments applied.
Origin · Russia, Ural · discovered 1830
II — The Emerald Carving
120.34
Carats · Hand-carved · 40.29 × 33.60 × 21.36 mm
A Russian emerald of extraordinary size, preserved in its carved form rather than faceted — the stone's natural structure left largely intact. Russian emeralds are distinguished by lower iron content, giving them vivid yet soft pastel greens and atypical clarity. Specimens of this scale from Ural deposits are exceedingly rare.
Origin · Russia, Ural · Malysheva mine
III — The Colombian Emeralds
48
Stones · Pear brilliant · 1.62 ct to 0.44 ct each
Colombia supplies an estimated 90% of the world's finest emeralds. These 48 pear-shaped stones display Green to Vivid Green saturation — the benchmark of Colombian emerald quality. The Muzo and Chivor mines of the Eastern Cordillera are the most prestigious sources for stones of this colour depth and clarity.
