Initial C Letter Series Mother of Pearl and Diamond Signet Ring

Black mother-of-pearl is rarer and harvested from shells that breed black
pearls—which are among the most prized pearls in the world. These shells are more difficult to cultivate and produce nacre with richer, deeper, and more vibrant color shifts (pink, green, violet, even gold). In pearl grading, black pearls are second only to golden pearls, placing their source nacre—black MOP—at a similarly high grade.

Due to their rarity and exceptional beauty, black pearls form under rare and precise environmental conditions, exhibiting intense overtones and body color that is difficult to replicate. The nacre that produces them—black mother-of-pearl—is thicker, more lustrous, and more colorful than standard white nacre, making it highly desirable in luxury jewelry.

Only the top 1% of cultivated mother-of-pearl meets our strict standards for engraving:

1. Large size to allow full pattern or letter carving

2. Smooth, flat surface for clean engraving and durability

3. Vibrant iridescence with strong multicolor reflections

4. Structural integrity, ensuring the nacre doesn’t chip or flake during engraving

You can choose any of the 26 English letters (A–Z). Each is engraved in a VAUDEVILLE font, elegant yet expressive.

We offer deep customization—you can submit a personal design, meaningful icon, or illustration, and our artisan will hand-carve it into the mother-of-pearl for you. And if you have any other questions about custom, please contact us at our service email service@brilliantcts.com.
