I will be doing a 2 part tutorial on the effects of baking a cubic zirconia in the oven,
Instructions: Clean ring or cz piece (leave no fingerprints on the stones!!!) 2. Place piece on foil or metal pan. 3. Set in oven (DO NOT PREHEAT!) 4. Set oven temperature to 350 degrees. 5. Bake for 3 hours. 6. Leave in oven till oven has completely cooled, it is important to not expose stone to drastic temperature change.
After it's done inspect cz to see of you have achieved your desired goal in color and clarity. If not repeat the steps above until you are satisfied
