The answer to the question is **no, cubic zirconia does not pass a diamond tester**. Diamond testers rely on thermal conductivity to distinguish between diamonds and other gemstones. Cubic zirconia, being a diamond simulant, does not have the same thermal conductivity as a real diamond, and will not pass the test.
