The third printing of Alan Hodgkinson's book that was first released in 2015 is now available. With Alan stepping back from teaching gemmology this will likely be the last printing of Gem Testing Techniques by the Hodgkinson family.

Part-time business work/life balance


You can only order one copy per transaction/order but you can come back for more than one transaction in a new session. If you wish to order several copies contact us directly

Beyond the initial launch when books are not limited, we will release a small quantity of books each month for sale. When we release books online we will announce this on our Facebook page.
This allows us to fit our other work commitments and lives around selling the book.

We are not a 'fast turnaround' business. In most instances, we will ship your book within three weeks of payment clearance, however it may take longer than this.

It took Alan Hodgkinson a lifetime of gemmological exploration to create the content for Gem Testing Techniques. We think the book is worth waiting for and we hope you agree!

As the platform we use doesn't have an address look up function for the UK, please make sure the postage address you give matches that on the UK Royal Mail database.

Correction from first edition

We found one error in the First Edition (though there may be others) which has been corrected in the subsequent reprints and that correction followed through to instances in the index. Page 392, Feld-18a, bytownite changed to labradorite.
There were a few minor graphic errors in the second printing i.e. where arrows had slipped on imagery that have been corrected in this third printing.
There are bound to be other errors we haven't spotted yet.
