Product Features:
- Open Design: The open, adjustable band fits different finger sizes, offering enhanced comfort.
- Main Material: Crafted from high-quality copper, ensuring durability and long-lasting color.
- Craftsmanship: The advanced lab-grown diamond setting technology is used, with each diamond carefully cut and set to ensure its brilliance and beauty.
The Royal Gemstones Ring is not just a piece of jewelry but also a work of art. It is suitable for various occasions, whether for daily wear or special events, and will showcase the wearer’s elegance and taste.









The Eternal Token
The founder of CotaJewelry, Ms. Coco, hails from Hungary. Her inspiration for jewelry comes from a precious memory—during a trip to Paris, her husband, under the Eiffel Tower, crafted a ring from a Coca-Cola bottle as a symbol of his proposal. Although the ring was accidentally lost, the love and promise it carried deeply touched Coco’s heart.
This cherished memory made Coco realize that the true meaning of jewelry lies not in its outward beauty but in the eternal emotions and stories behind it. Thus, she founded CotaJewelry, hoping that each piece of jewelry would be like that ring—a witness to love and blessings, accompanying every wearer through life’s most important moments. No matter how time passes, this precious sentiment will never fade.
