Natural Ametrine
Serpent Duality Pendant
925 Sterling Silver
Two serpents coil around a natural ametrine — violet crown dissolving into warm gold — their bodies forming a living frame in 925 sterling silver with gold-tone accents. Flip it over and the Flower of Life is revealed, hand-pierced into the silver reverse. Protection on one side, sacred geometry on the other. One of one.
Blue Topaz & Multi-colour Tourmaline
Tourmaline Bridge Pendant
925 Sterling Silver
Seven stones, one statement. A vivid Swiss blue topaz anchors the centre, flanked on each side by three hand-selected multi-colour tourmalines — each one a different hue, no two alike. Set in 925 sterling silver with a permanent chain attached at both ends. Classical in form, impossible to ignore in colour. One of one.
Natural Ametrine
Ametrine Soleil Pendant
925 Italian Silver
A one-of-one pendant centred on a natural ametrine — its crown radiates warm golden-yellow, dissolving into deep violet-blue at the base. The stone is bordered by a continuous line of 1mm brilliant-cut diamonds, hand-set in 925 Italian silver. Entirely handcrafted. No two will ever exist.

Ethiopian Pin Fire Opal
Chevron Opal Pendant
925 Italian Silver
A 13.7ct Ethiopian pin fire opal — its surface alive with scattered constellations of red, green, and gold — bezel-set within a hand-engraved Chevron frame in 925 Italian silver. The reverse bears the full Chevron pattern, stamped Yusei & Co. 925. Worn as a statement of quiet authority. One of one.
