Quick Tips
- Measure at the end of the day, when fingers are largest.
- Snug, not tight — the ring should pass your knuckle with slight resistance.
- Wider bands (4mm+) fit tighter — consider sizing up half a size.
- Between two sizes? Always size up.

Our Diamond Serpent Coil Lab Grown Diamond Fashion Ring is the most daring statement piece in our collection — a sculptural tour de force where fine metalwork and lab grown diamond brilliance combine to create a ring that is as much wearable art as it is jewellery. A coiled serpent wraps its textured, scale-covered body around the finger, its raised bubble/scale texture catching light from every angle across the full circumference of the ring.
The serpent's head rises proudly at the top, framed by a bold milgrain bead border and adorned with a glittering pavé cluster of round lab grown diamonds — the snake's crown jewel — with additional accent lab grown diamonds sparkling along the head's edges. The tail coils elegantly at the reverse, completing the full serpentine form. The serpent has symbolised wisdom, transformation, and eternal power throughout history's greatest civilisations. Wear this ring as your own symbol.
Available in 10K/14K/18K White, Yellow, or Rose Gold and Platinum.
