Good diamond (1.52ct), Usually GIA wiil not give it excellent grade if it was too shallow !

What is the girdle thickness ?


The price is not too bad either, maybe better around 10,000.00

HI Everyone!

THEWOOD- neither the GIA or most in the trade would say that 59.2% is 'shallow'

Generally speaking, when a diamond is cut too shallow, there is a 'fish eye effect'- which is a ring that shows inside the table.

If a diamond is too deep, it will have a dark center.


It's important to remember that if two stones are well cut, one being 60% depth, the other being 62%, in many cases the shallower stone will appear to be larger- so going deeper does have down sides as well.


Generally folks around here like 'Ideal' cut diamonds- which tend to be slightly deeper than other well cut diamonds.

But that does not mean that other combinations of depth table are not beautiful. Many people choose slightly larger, 60%+- depth stones after looking at both.,

Neither is 'wrong' it's personal preference.

You're in a great position to look at both stones since you're shopping B&M.

Have a look for yourself and see which you love better.

IN terms of the GIA grade, 'Excellent' is the top grade- but there are MANY awesome stones getting'only' Very Good' on the cut grade-

If the lgf% aka lower halfs are on the long side it can be a very good combo.
It would tend to favor brightness over fire which some people like.
I would say that the GIA grade is a little harsh if the lgf% is on the long side and about right if they are around 75%.
Trust your eyes, if it speaks to you after viewing it in multiple lighting conditions and comparing it to a more traditional ideal cut then go for it.
Price is high for internet pricing but b&m prices run higher.
