Gridle size help !!!!!

[betection]

for a 1.14 carat stone what does it means when the cert says "0.7-1.2" under the girdle

what does a 0.7-1.2 girdle mean? does it mean thin, thick or what ?

This was posted about girdle thickness by leonid a little while back:

-----------------------------------------------------
GIA
Extremely thin 0.00 - 0.08 mm
Very thin 0.08 - 0.12 mm
Thin 0.12 - 0.15 mm
Medium 0.15 - 0.20 mm
Slightly thick 0.20 - 0.23 mm
Thick 0.23 - 0.33 mm
Very thick 0.33 - 0.40 mm
Extremely Thick: greater than 0.40 millimeters

AGS
Very thin 0.091 - 0.50%
Thin 0.51 - 1.2%
Medium 1.21 - 1.7%
Slightly thick 1.71 - 2.95%
Thick 2.96 - 4.2%
Very thick 4.21 - 5.7%
Extremely Thick: >= 5.71 %

HRD
Ex.Thin 0.0 - 0.5%
Very Thin 0.5 - 1.5%
Thin 1.5 - 2.5%
Medium 2.5 - 4.5%
Sl.Thick 4.5 - 6.0%
Thick 6.0 - 7.5%
Very Thick 7.5 - 8.0%
Ex. Thick 8.0 - 100%

Me again, so take with a grain of salt:
The girdle is wavy as it goes around the diameter of the stone with peaks and valleys in it's thickness. GIA and AGS measure the girdle at the valleys, while HRD measures it at the peaks. i'm assuming the measurement you gave (1.2-1.7%) was from the valley which makes it a Thin girdle, which is perfectly fine.

The range means mininum and maximum, so your girdle at it's min areas would be the .7 and max would be 1.2. That is thin...not a bad thing. As the other poster noted, where it's wavy is where you will find the mins and maxs...the numbers just give you a clearer picture of the girdle and possibly stone symmetry. You don't want a girdle that is .7-2.9...because that thing would be all over the map!

The minimum and maximum areas will always be from the same part of the girdle either the valleys or the peaks I understood.

pyramid,

I'm pretty sure you're right.

In this case, the thickness of the VALLEYS of the girdle vary from a min of 0.7% thickness to a maximum of 1.2% thickness.

I think that's what Mara was saying as well.
