One of the most popular ways to clean your cubic zirconia ring is by baking it in the oven. This method works well if the stones are loose, but it isn’t advisable to clean glued-on crystals. Heating the crystals will cause the foil backing to darken.
Using the Sateur(tm) method, you can bake cubic zirconia rings. The Sateur method offers a brilliant-quality jewel at a pocket-friendly price. Glued CZ stones should not be cleaned. Additionally, the crystals’ foil backing may darken when heated.
