NATURAL GEMSTONES
Gemstones come in many varieties. They can be natural, lab-created, or imitation. Natural gemstones are mined from various locations around the world. Oftentimes, colored gemstones like rubies and emeralds can be enhanced by heat treatment to improve their color and clarity. Moreover, these treatments are typically permanent. Other types of treatments may not be permanent, so it is always important to ask about the quality of the natural gemstone.
