How Can Identify A Diamond?
Difference between Real Diamond and CZ
Hardness:
CZ is not real diamond and its hardness is also much less than diamond which is the hardest of all Gemstones.
Diamond can scratch "Cubic Zirconia" without difficulty but "Cubic Zirconia" can not scratch diamond.
Weight compared to size:
A real Diamond with the same size of a "Cubic Zirconia" will be lighter in weight. (Carat - A measurement of weight.) One metric carat is equivalent to 0.2 grams. Do not confuse the terms Carat and Karat. (KARAT: A measurement of gold purity.)
Read through effect:
Original diamond when placed table down on a printed matter (preferably a line) and examine from above the girdle (sharp side - Pavilion side) will not exhibit read through effect but "Cubic Zirconia" will display low read through effect.
Inclusions:
Real Diamond will have black metallic inclusions like iron and nickel where "CZ" will have white un-melted powder which sometimes appears like gas bubbles.
Ask for a diamond certificate if you are unable to identify:
