Signet rings have been worn for centuries as a mark of legacy, power, and personal identity. Once used to seal letters, they’ve evolved into a fashion-forward staple that blends heritage with modern design. Our collection pairs this historic form with the fire of moissanite—for a ring that’s bold, ethical, and unmistakably yours.
Our moissanite signet ring collection includes:
Round, oval, and square face designs with central moissanite stones
Initial or monogram signet rings accented with pavé moissanite
Minimalist flat-top styles with subtle sparkle
Customizable engravings and shapes for one-of-a-kind pieces
Chunky and slim profiles for both men and women
Each ring is made in solid 14K & 18k gold—available in yellow, white, or rose—and features GRA-certified moissanite, lab-grown for exceptional clarity, brilliance, and ethical peace of mind.
We use only 100% solid 14K & 18k gold, never plated or filled—so your signet ring holds its strength, shape, and luxury for a lifetime.
