Hi All!

 

So I was handed my first GIA grading report today (along with a diamond). I think I have a general understanding of the 4C's, but I need some clarification on some things. Let me give you some info of a diamond I'm looking at.

 

weight: 0.87

depth: 60.3%

table: 62%

griddle: medium to slightly thick, faceted

culet: none

finish: very good

symmetry: very good

clarity: VS2

characteristics: crystal, feather

colour: E

price: $3500 US

 

I need some clarification on the table and depth percentages. Are these numbers acceptable? Or should I be looking for a diamond with better table and depth percentages? Is this going to significantly affect the way the diamond looks? And with the clarity characteristics of crystal and feather, should I be concerned about these? Do any red flags go up when you see any this information?

 

Thanks

Ken.

In order for you to be able to decide if it is "acceptable", you need to compare it to other diamonds that differ in their table and depth measurements.

 

Comparisons will allow you to decide which combinations appeal to you.

 

Not to get too technical, but keep in mind that a diamonds' visual appeal depends not only on table and depth, but also Crown/Pavillion angles, Crown Height, and the cut angle and size of the upper and lower minor facets, and their proper placement. All 58 facets of the round brilliant work in concert.

 

You can therefore readily have two diamonds with the same table and depth numbers that will look markedly different.

 

"Numbers" can be a good guideline, but don't geek out on them.

Thanks Barry. I'll take your advice and sit down with a few different diamonds and compare.

 

Just as guide though, what do you think of this diamond?

Might be a nice stone, not enough info, though, to say more.

To give you an idea of what Barry means by "not enough info," let me ask you what you think of the following car:

 

Red

4 tires

1 steering wheel with leather wrap

2 doors

2 white lights out front and 2 red lights out back. The ones in the back can blink alternating, or together.

a trunk that lifts up

upholstered seating

under the front hood is a V-6 engine

 

What's your opinion, should I buy it? :wacko:

Princess,

 

Obviously buying a diamond must subjective as well as objective. I have a better understanding of that now. How important are the GIA numbers when buying a diamond?

 

Back on the topic of cars...if I gave you the following information, maybe you could let me know if this was a nice car.

 

red in colour with some rust

four tires, but three are flat

a steering wheel, leather wrapped

2 doors

lights in the back & front, really bright

a trunk that doesn't open

upholstered seating, furry lamb skin

and a V-6 engine, with only 5 good cylinders

price $20,000 USD

Don't forget to mention that it's a 1967 Ferarri sportster that was featured prominently in a James Bond movie and has been in the collection of a Saudi prince ever since.

 

Yes, this is a nice car.

How important are the GIA numbers when buying a diamond?

-------------------------------------------------------------------------

 

Well to start with you only have 2 numbers. An average table percentage and a total depth percentage which is based on an average diameter. Not much help. It would be like saying I have a house that is measuring 40 feet on one size and 20 feet on the other side. What does it look like? I think you have to *see* the stone and compare it side by side with other diamonds to tell if you have a nice one or not. Some may tell you to get a stone with ideal numbers, but we have seen stones that are not ideal cut outperform some ideal cut diamonds..... see what I mean? A round brilliant cut diamond has 57 facets, so a couple of averages leaves you pretty much blind on how it actually looks to the eye. Each facet is important in working together to bring the light back to the eye. Haven't seen a lab report yet that can communicate that.

For those that want to know the truth about diamonds, just ask.
