Profile View of Diamond

Question: I had been browsing diamonds online for quite some time now and intend to buy one in the next few weeks. During my research, I had noticed many diamonds exhibit girdle thickness that seem to vary quite wildly from each other.

For example, thin – medium girdle thicknesses are typically seen in round diamonds. We see a larger fluctuation in fancy cuts such as thin – extremely thick, medium – slightly thick, thick – extremely thick, thin to very thick and the list goes on for girdle thicknesses. (more…)

Are There Differences in Grading Standards of Fluorescence Between AGS/GIA vs EGL?

Diamonds With Faint Blue Fluorescence

Today’s question is asked by James from Indianapolis. Fluorescence is a common property found in the majority of polished diamonds and I wanted to do this post so that the answer would benefit more readers.

Round Diamond Comparison – Depth Lower than Table %

Hi Paul,

I came across these 2 diamonds on James Allen and was stumped by what I saw in the Idealscope images.

– jamesallen.com/diamonds/I-VS2-Ideal-Cut-Round-Diamond-1493120.asp

( Update: These 2 diamonds had been sold and removed from JA’s listing. )

First of all, I want to mention that I had read through your entire site on choosing a diamond. Great stuff. Good information. However, this particular phenomenon was not covered in your articles. Perhaps you did and I couldn’t find it. If that’s the case, could you point me in the correct URL.

Here’s my question: Why is the Idealscope image for the G SI1 diamond so weird looking? It has alot more blacks than the usual Hearts and Arrows I had seen on your website.

By comparison, I picked out an I VS2 and now, the idealscope image looks ‘normal’ to me. (more…)
