How To Sell Loose Diamonds In The UK Without Losing Value?

Preparation is the key if you intend to sell loose diamonds to UK buyers at a fair value. In contrast to jewellery, a loose diamond is priced based on its unique characteristics associated with the 4Cs — cut, colour, clarity, and carat weight as well as certification, market demand, and overall condition.
Even if you received a diamond as an heirloom, no longer want that stone, or want to release its value, selecting an experienced buyer along with understanding the valuation process can help prevent you from accepting a lower bid than you believe your diamond may fairly generate.
Quick Summary

Have your diamond professionally assessed before accepting an offer.
Having a clear and recognised grading certificate can simplify the process of valuation and make the asset more transparent.
Do yourself a favour and compare better loose diamond buyers in the UK instead of going with the very first quote.
Also, realize that resale value is not the same as the retail price initially paid.
The best thing to do here is to ask for a straightforward breakdown of how the offer was reached.

An experienced buyer can help you determine if having your diamond independently graded is worth the expense.
