PLEASE, ADVISE ON THE FOLLOWING DIAMOND:

 

WEIGHT 0.40 CT

CLARITY VVS1

COLOR F

CUT GOOD (EGL BELGIUM CERTIFICATE)

4.55 X 4.52 X.2.98

DEPTH 65.7%

TABLE 63%

CROWN HEIGHT 14

PAVILLION DEPTH 44

 

PRICE (TOGETHER WITH 18K GOLD RING) 1250 EUROS.

 

WHAT SHOULD I PREFER, THE ABOVE DIAMOND ACCOMPANIED BY AN EGL CERTIFICATE OR A DIAMOND WITH NO OFFICIAL CERTIFICATE (THE JEWELLER WILL WRITE AND SIGN THE CERTIFICATE).

No is not good for many reasons:

 

1) It is WAY too deep, really consider something like 62% depth as the maximum, something in the 61.x range is much better.

 

2) Because of the extreme depth your diamond actually looks like a .30ct diamond because an Ideal 0.40ct RB should be ~4.8mm.

 

3) EGL, they're not very consistent in their grading and people have often reported them for example scoring a diamond's color 2 grades off from what it really is (i.e. they say it is something better than it is).

 

It does have a wonderful color and clarity but because EGL say this it's probably a VVS2/VS1 and color G/H so be careful.

Unless the EGL Belgium people have changed their format recently, they don't include crown height and pavilion measurements on most of their documents. Where did this information come from?

 

Why didn't they list the girdle? A bit of arithmetic (Depth = Crown + Girdle + Pavilion) comes up with 7.7%, which is extremely thick. Something tells me that it was not a cooincidence that this was omitted.

 

There's nothing 'official' about an EGL lab report, or any other lab report for that matter. This is a 3rd party opinion about some of the attributes of the stone that customers may find important. They are not certifying anything. The signed statement by the selling jeweler, on the other hand, is a warranty. Get both. As Gforce points out, EGL doesn't enjoy the best reputation for consistent grading and they don't use the same grading scale as many of the other labs. This can be an important problem if you are using one of their reports to compare several stones.

Very good advice.
