Look at the weight first. No matter where the garnet bracelet is made, its density is higher than that of ordinary crystal. You can cut the beads and weigh them five times, and then weigh five other kinds of crystal beads (agate, white crystal, amethyst and topaz are all acceptable).
Comparing the two data, the real garnet bracelet is obviously heavier than ordinary crystal, and the difference is generally above 10%. Pay attention to the same size of beads when weighing.
Second, draw glass. Garnet is very hard and it is easy to leave marks on the glass. If you can't even open the glass, it must be a fake.
Third, look at impurities. Natural garnet bracelets are full of cotton wool, and basically have inclusions such as preserved eggs and pine flowers, which can be seen clearly with a flashlight. Pure substances are very scarce. If you encounter hundreds or even dozens of clean and transparent garnets, you must be vigilant. The probability of artificial synthesis is very high!
Fourth, get started. Natural garnet has a greasy feeling similar to Hetian jade, which is much warmer than ordinary crystal.
Fifth, the above methods are still unable to identify the authenticity of garnet, and things are still relatively expensive. I suggest you go to a professional appraisal institution for appraisal.
