Gemstone Testing 

Holts' professional gemstone testing service will give you peace of mind regarding the identity of your gemstone or mineral.

Our qualified Gemmologists will provide you with a certificate stating the type and variety of gem material and will also list all the physical characteristics of the piece such as weight and measurements. If you would like to use our gem testing or valuation services please visit our showroom in Hatton Garden.

Charges for gem testing start at £47 per piece. Please contact us regarding prices on jewellery identification reports and prices on larger lots of loose gemstones.
