The Ultimate Diamond Buying Guide

Read our Ultimate Diamond Buying Guide which explains more about how each individual component affects Diamond Pricing. In our experience as gemstone dealers, we have amassed a lot of industry knowledge after seeing hundred thousands of Diamonds. Predominantly as gemstone traders, we know what to look out for and would like to share our comprehensive knowledge to our clients.


This guide will be more detailed that other Diamond Buying Introductions that you may find. It includes our opinion and experience in jewellery appraisals from working in International Auctions and Pawn Brokering. Our Ultimate Diamond Guide will also ensure that your questions are answered, and you will have the theoretical knowledge of a Professional Diamond Grader and market expert after reading. This knowledge will empower you to choose a diamond that maximizes your budget by knowing what to look out for. We will also provide our opinions on certain types of diamonds – if they retain their value after purchase.



This is a professional guide that will go straight to the point. If you would like to know more about general diamond properties, our Introduction to Diamonds will provide that information.
