A genuine diamond is a starry and shining masterpiece. It's an artwork that will leave you spellbound. It's brilliant cut and dazzling shine that makes it the monarch of all gems. Differentiating a real diamond from a fake one, however, is a very difficult task involving a great deal of finesse and attention to details. Whether you're in the market to buy a ring or to inspect your own jewels, it'll be required by you to know the authenticity of your stone. There are several fake counterparts of diamonds that can easily be confused with genuine diamonds — natural gems with a strong resemblance to diamonds such as colourless sapphire, colourless topaz and colourless zirconium. There are also gems in the laboratory such as YAG (yttrium aluminium garnet), GGG (gadolinium gallium garnet), CZ (synthetic cubic zirconia) and synthetic moissanite which look like true diamonds to the average person.
