All you always wanted to know about jewelry appraisal


Do you know the value of your jewels? Your collection of precious pieces, that are received, inherited or even bought as special treats, grows bigger over the years. While the jewels are usually stored in a safe place and treated with care, it is difficult to keep track of their value. Indeed, invoices get lost and jewelry value fluctuates. Therefore it is important to have jewels, watches and gemstones estimated by a professional before a burglary, a loss or an accident happens.

First of all, what exactly is an appraisal ?
