The number of this experiment is: Emerald (A) bracelet identification certificate. Total mass 27.60 shape bracelet color light green+brownish yellow density 3.33 uneven polarization aggregate refractive index 1.66 (spot measurement) absorption spectrum jadeite characteristic spectrum amplification inspection fiber column interwoven structure Remarks * * * * Hello, bracelet A of natural jadeite looks like water in photos, with delicate foundation and poor permeability. My estimate is in the range of 1200, with average color and no damage, cracks or defects. If the object is more transparent and shiny than the photo, the value will be higher. The trading environment is different and the price is different. Shopping malls and tourist areas have higher transaction prices. Of course, if you don't see the real thing, there will be errors in the valuation. I hope the answer can help you.
