Elphaba
A 1.39-carat emerald-cut watermelon tourmaline and a 0.33-carat lab diamond, set opposite each other on a 10k yellow gold band — one stone formed over millions of years in two colors, one grown in weeks in one. The toi et moi format exists to hold a conversation between stones; these two have the most to say to each other of any pair in the drop.
The Object
- Name: Elphaba
- Silhouette: Toi et moi, two-stone opposing claw prong setting
- Edition: One of one
- Size: 4.5
- Collection: Diptych
The Stone
- Type (center): Natural watermelon tourmaline
- Cut: Emerald cut
- Carat weight: 1.39 ct
- Color: Watermelon — green base with red saturation toward the surface; deep, saturated throughout
- Accent stone: 0.33 ct lab-grown diamond, six claw prongs
- Certification: Both stones uncertified — selected by eye for how they read together
- Grade significance: Watermelon tourmaline with this depth of two-tone saturation is rare at any size. The color gradient here runs clean through the stone rather than pooling at the edges.
The Metal
- Metal: Solid yellow gold
- Gold content: 10k (41.7% pure gold, 417 stamp)
- Gold weight: 2.20 g
- Finish: High polish
10-karat gold is the strongest everyday gold alloy — more scratch- and dent-resistant than 14k or 18k, with a warmer, quieter tone. We chose it deliberately, for jewelry that’s meant to be worn, not stored.

Care
Solid gold is durable enough for daily wear, including water exposure. For longevity, we recommend removing the ring during high-impact activity (weight training, rock climbing, manual labor) and avoiding direct contact with harsh chemicals including chlorine, bleach, and acidic cleaners. A soft-bristled brush and mild soap in warm water is sufficient for home cleaning. Note: Elphaba’s claw prongs can catch on fabric; we recommend extra care around knitwear. Complimentary cleaning, polishing, and inspection within the first year of purchase — see our Warranty & Repairs page for full coverage details.
