Color Change Watermelon Tourmaline Petite Circle Diamond Ring

A stone that plays a trick on the eye depending on the light, this 1.27 carat green tourmaline shifts subtly between tones as she catches daylight versus incandescent light, a rare and little-known phenomenon in fine gemstones. Set in Yi Collection’s signature modern design, she rests in a bezel setting with a delicate diamond dotted band.

Natural and untreated, color-change tourmaline is exceptionally uncommon, a genuine curiosity for the collector who appreciates a gem that keeps a little mystery. She looks different in every room, and that’s exactly the point.

Crafted in 18k yellow gold, this ring is understated on the surface and full of surprise underneath, the kind of piece that invites a second look.

Handcrafted by master artisans in our Bangkok atelier.
