Do lab grown diamonds pass a diamond tester?

Yes, lab-grown diamonds do pass a diamond tester. They have the same physical, chemical, and optical properties as natural diamonds, which includes their ability to conduct heat and electricity.

Therefore, when tested with a standard diamond tester, which measures thermal or electrical conductivity, lab-grown diamonds will typically show up as real diamonds just like their natural counterparts.

However, specialized equipment used by gemological labs can differentiate between lab-grown and natural diamonds.
