This inexpensive and easy to make projector will quickly let you know if that "diamond" you are wondering about is actually a genuine diamond or an imitation such as a cubic zirconia. Under sunlight, cubic zirconia is hard to tell from a genuine diamond by the average person. However, it is easy to tell them apart using this detector. The Genuine Diamond Detector uses only two relatively inexpensive electronic parts plus a battery and battery connector.
