This item is made with nickel‑free de‑ox sterling silver, which is formulated to be more resistant to tarnish. De-ox sterling is a modern .925 sterling alloy that incorporates germanium for improved tarnish resistance. It offers the same beauty and weight of traditional sterling with longer‑lasting shine and easier care. All sterling silver can tarnish naturally over time, and factors like moisture, chemicals, or individual skin chemistry may cause it to occur more quickly.

About Lab-Created Sapphires:

Lab-created sapphires are genuine corundum with essentially the same chemical composition, durability, and Mohs hardness of 9 as natural sapphires. Unlike natural sapphires, which form within the earth, lab-created sapphires are grown in controlled laboratory environments.

Growth Method: Flame Fusion (Verneuil)

Regardless of the growth method, lab-created sapphires are genuine sapphires, not simulated stones or imitations.

Some model images may be AI-assisted to demonstrate approximate scale, available size options, and styling. Full-model images are intended as styling visualizations. The first several images always feature the actual jewelry, and the piece you receive will match the specifications stated in the listing.
