Materials
Sterling Silver

Sterling silver comprises 92.5% pure silver and 7.5% other metals, primarily copper. It is marked “925” or “S925,” signifying its high silver content. Affordable and 100% recyclable when unplated.

Vermeil

Vermeil is sterling silver coated with a thick layer of gold (minimum 2.5 microns, 10K or higher). Due to its thicker gold layer, it offers a more durable golden color and may be better tolerated by sensitive skin, though reactions are still possible.

14K Gold

14K gold comprises 58.3% pure gold and 41.7% alloy metals. It is commonly stamped as “14K” to indicate its composition. Durable for everyday wear, recyclable, and often well-tolerated, though sensitivities may still occur.
