Materials

Our sterling silver is S925, meaning it is made with 92.5% pure silver and 7.5% alloy for added durability. It is nickel-free and finished with a palladium coating to enhance shine, brightness, and tarnish resistance. This gives our silver a clean, bright finish while remaining a better option for sensitive skin.

Gold vermeil is a thick layer of gold plated over a sterling silver base. Our vermeil pieces offer the look of solid gold while maintaining the quality of sterling silver underneath. It is a beautiful option for everyday wear, with a warm, rich finish that feels elevated and timeless.

Rhodium-plated sterling silver is sterling silver finished with a layer of rhodium for a brighter white shine and added surface protection. This finish gives the piece a polished, luminous look and helps reduce tarnishing, making it a refined choice for everyday wear.

Our sterling silver pieces are nickel-free and palladium plated, making them a more comfortable choice for everyday wear and for those with sensitive skin.

Sterling silver can naturally tarnish over time, especially when exposed to moisture, oils, or chemicals. Our palladium-coated sterling silver is designed for added brightness and better tarnish resistance, but like all fine jewelry, proper care will help maintain its finish over time.

To keep your sterling silver looking its best, store it in a dry place and avoid direct contact with water, perfume, lotion, and household chemicals. Gently wipe your jewelry with a soft cloth after wear to help preserve its shine.

Gold vermeil should be handled with extra care to protect its finish. Avoid water, sweat, perfume, and harsh chemicals, and store it separately in a soft pouch or jewelry box when not in use. Gentle wear and proper storage will help extend the life of the gold layer.

Rhodium-plated jewelry should be kept away from moisture, chemicals, and abrasive surfaces to help preserve its bright finish. Over time, the plating may naturally wear with use, and proper care will help it stay beautiful longer.

Yes. Jade is valued for both its beauty and durability, making it a meaningful choice for everyday wear. Because each jade piece is natural, slight variations in color and texture are part of what makes every piece unique.

Jade should be handled with care and stored safely to avoid knocks or scratches. To clean, gently wipe with a soft cloth and avoid exposure to harsh chemicals, ultrasonic cleaners, and prolonged moisture.
