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.
