I bought topaz from the Royal Thai Jewelry Center. Is it true or not? how much is it? Have you been cheated? How much is it in China? Is it worth it?
Sapphire is a general term for corundum gems of other colors except ruby. Orange sapphire is a rare colored sapphire, so it is recommended to inspect it, because Thailand is most famous for its color-changing gemstones, filled gemstones and artificial gem. Even if it's fake, you can prove it. Most people can't understand English.
