Here is a small video of the two stones I used in the video "Measuring the Specific Gravity with hydrostatic scale in Gemology ". The CZ is on the right side and show a lot of fire comparing to the diamond. The matter here is that the diamond have only a good cut and symmetry and that play a lot on how the light is travelling into the stone. The objective here is to show that people who do not know about diamonds and gemology can be fooled very easily by a nice imitation and CZ is the best in the market today and cost nearly nothing comparing to a natural diamond.
Remember that the CZ have a density nearly twice higher than the diamond and you can feel it in you hand. Sorry for the bad quality of this video...
