An expert opinion is a document with complete information about a piece of jewelry or a precious stone. It shows the nature and quality of the jewelry.
The price is indicated for one stone (beryls, garnets, quartz, opals, topazes, tourmalines, zircons, etc.)
For a piece of jewelry (or batch), for each subsequent stone of the same type and size group in the same expert opinion, there is a 30% discount from the tariff.
For individual stones weighing more than 20 carats, the cost is determined individually.
