The color quality of red garnet can be divided into purple, rose plus purple, rose red and wine red from top to bottom. The brighter the color (the best garnet is not black in the dark, but still emits red light), the more transparent the crystal (the brighter the color, the better), and the less ice cracks, the better. In addition, we should also require that garnet comes from Brazil, not Qinghai, China. You can see what grade your garnet has reached and estimate the price yourself. Okay, garnet ranges from 30 to 60 yuan per gram. Beads larger than small beads are collectible (the diameter of beads should be at least 5mm, otherwise there is no collectible value). Cheap 1, a new bracelet in 200 yuan, also has tens of dollars. In addition, the purchase of garnet should also go to merchants with good quality and good reputation, which will be more reassuring.
All the above are from experience, I hope it will help you a little.
