Diamond Ring Buying Guide: How to Evaluate, Identify, and Select Diamonds & Diamond...

Reader Reviews
This book is definitely a great resource to have when you're buying a diamond. I picked this up near the end of my search, so I had come to know most of the basic diamond information like acceptable table ranges, clarity and color ranges. The photos were extremely helpful because no other source I have come across provides you with full color close ups and defections of inclusions. What's a knot, feather, facet? What do they look like? Are they bad? *Princess Cut*I was looking for a princess cut diamond (the square one) and unfortunately this book mostly focuses on rounds. That's important insofar as the acceptable table and depth proportions are slightly different for princess cuts (FYI-get below 80%, around 70% is even better). Don't disregard the dimensions! At first I only judged size by carat weight, but a lot of that weight can sit below the diamond-hence you want a lower depth percentage. For example, a 2.0 carat princess cut that's 7.11 x 7.14 will look bigger than a 2.30 carat that's 6.69 x 7.30. With princess cuts, you also want to be as square as possible-anything with a length to width ratio bigger than 1.04 starts looking rectangular. Another thing to keep in mind is the difference in Gemological Certificates. I found out early that an EGL G SI1 is just not the same as a GIA G SI1. Make sure you're comparing apples to apples here. There should never be a $1000 difference in price for the same cut, color and clarity. I found GIA much more consistent and rigid than EGL and eventually just ruled out the EGL certified diamonds. Try it yourself: ask to see the same size, color and clarity in GIA and EGL, 9 times out of 10 the GIA is more colorless and has fewer inclusions. ...
