Cubic Zirconia Shop: Sterling Silver CZ Jewelry  

Lab-Created Brilliance in .925 Sterling Silver Settings

Cubic zirconia emerged as a jewelry stone in the 1970s after Soviet scientists developed methods to stabilize zirconium oxide crystals. The material occurs in nature but remains too rare for commercial use, so all jewelry-grade CZ is synthesized. This controlled production allows for precise color grading and clarity that natural stones cannot guarantee. Our collection uses colorless and colored CZ varieties, each cut to maximize light return. Sterling silver provides the setting for every piece in this collection. The .925 silver standard means 92.5% pure silver alloyed with copper for strength. This combination resists the bending and warping that pure silver experiences while maintaining the white metal luster that complements CZ's brilliance. We have served customers from our US location since 2005, shipping each order at no additional cost within the United States.
