Jade is considered a royal gemstone in China. While we recognise jade as being light green, it also comes in yellow, lavender and white. It is very common to sell fake jade, especially to Westerners. Know how to tell if your jade beads are the real deal or if you have beads made of green plastic, acrylic or cloudy glass.
Hold the jade beads up to the light. Most real jade has imperfections and fibrous patterns when held up to light. Fake jade will be perfectly homogeneous.
Hold the beads up to your face since the nerves on your face are more sensitive to temperature than on your hand. Jade contains property that makes it cool to the touch. Fake beads will absorb room temperature and not feel cool. Don't excessively handle the beads before putting them to your face.
Clink together plastic beads to observe their sound, then clink the jade beads next to the plastic beads. If the jade beads make the same sound as the plastic ones, it is fake. If the sound is louder and more resonant, it is real.
