We have made some changes to our Conditions of Sale and acceptance of credit cards. At the bottom of the page we have added a section “Delinquent Customers” to protect our customers from fraudulent buyers who may attempt to resell our products. Presently we have a dispute with Desjardins Card Services which used to be our merchant bank for credit card transactions.

The 3rd edition of the Diamond Handbook (2018) updates jewelry professionals and serious diamond buyers on new developments in diamond grading, treatments, synthetic diamonds, imitations and fancy-color diamonds. Using close-up photos, it shows how to make visual judgments about clarity, transparency, brilliance and cut quality. Basic and advanced methods of detecting diamond imitations, treatments and manmade diamonds are discussed and illustrated. Tables, charts, diagrams and more than 350 photos are included making this an excellent reference on natural, treated and CVD & HPHT diamonds. Highly recommended book order here.
