Should I Buy This Diamond?
Is a question we are frequently asked.
Here are the specs the consumer provided us based on the presentation of his Jeweler who recommended its purchase, calling it an "Ideal" Cut.
Round Brilliant Shape. GIA Grading Reprort
Measurements 6.37 - 6.41 x 3.96mm
Weight 1.00 carat
Price = $11,000.00
Proportions
Depth 62%
Table 56%
Girdle Medium to Thick, Faceted
Culet None
Finish
Polish Very Good
Symmetry Very Good
Clarity VVS1
Color Grade E
Fluorescence None
Even though this diamond has a grading report from the GIA, the foremost diamond grading lab in the world which is definitely a big plus, we recommended that he pass on this diamond.
Why?
Look closely. The correct and proper spread for a 1 carat round diamond should be in the range
of 6.44-6.55 millimeters and show a total depth percentage in the range of 60.7-61.7 percent with a girdle thickness that ranges from thin to medium. This leads to proper balance and enhanced light refraction.
This diamond with a spread of 6.37, depth of 62%, and a girdle thickness of Medium to Thick properly measures for a .96 carat diamond, not a 1 carat stone. Why did the diamond cutter do this?
Money.
The price differential between a .99 carat to a 1 carat diamond in this color/clarity combination is in the range of an extra 10-15%. Thus, the cutter "squeezed" the diamond proportions so as to attain the 1 carat size.
Do your homework and work with a reputable diamond vendor.

Wow- what a wonderful website! I do have a question for you, though. What are diamond accents? Are they real diamonds or more like a CZ?

Real diamonds that accentuate a center stone or a piece of jewelry, are called accent diamonds.

now you've got me worried...correct spread for a diamond? may i ask what the correct spread for an asscher cut would be? my boyfriend and i just put a deposit on an 1 carat asscher diamond that is an excellent cut, polish and symmetry, 58% table, 68% depth, G color but with a sI1 clarity...my question is should we buy an asscher diamond with that low of a clarity grade? and second, what is the ideal cut/proportion for an asshcer cut of that size??
ps. the cut is beautiful but the inclusion is right on the table...i can't see it personally but my boyfriend claims he "might have." what to do...

There is no such thing as an official designation of "Ideal Cut" for Asschers as there is for round shape diamonds. The architecture and facet alignment are different.
You've seen this diamond and say that the Cut is beautiful. That's great! Trust your eyes and go for it.

Hi have just brought an asscher but am not sure on the proportions. The table size is 60% and the dept is 78.4%. This is for a .84 with E colour and clarity vs1. Do you think this is ok?
