GEMSTONES

Unfortunately, there are misleading names for gems. Be particularly careful of gemstones that have Two names. For example, a Majorca pearl, which is a legitimate trade name, is an imitation pearl. Gemstones that have names with locations should also be questioned, such as African emerald. Diamonds, for example, can have strange prefixes, such as occidental diamond. Always ask questions.
