Thin Girdle Problem?

[flash_e_gt]

Hello eveyone....

I found the following diamond for $9K
1.52 / SI1H
Depth 60.7
Table 57.0
Crown 15
Pavillion 43.5
Culet None
Polish Good
Symetery Good
FL = Faint

My only question about it is the girlde...it is rated very thing to thin faceted...
What does this mean?

This means there are portions of the girdle that are succeptible to chipping. Sometimes it's not a big deal but more often it is. One good wack on an "very thin" or "extremely thin" girdle and you may be looking at getting it recut and by by 1.5xct size.

Does that mean I should be concerned about this stone? I was considering it. Should I keep looking for one with a thicker girdle?

Looks like a pretty awesome stone. I don't think I'd be too quick in eliminating it.

The big worry with girdle thickness is "extremely thin". This width has a "knife edge" that chips easily. "Very thin" is considerably safer than "extremely thin".

Also, you might only be dealing with a VERY small segment of the girdle which is "very thin" (usually the case). The rest might all be "medium". If this is the case, any risk is considerably reduced.

Remaining risk (if any) can be essentially reduced to near zero if a savvy setter protects the area with smart positioning.

as Richard says - often there is just one or 2 very thin parts where the orginal crystal was left under the stone. These can easily be set under a prong.

the first stone that started this thread is not all that well proportioned. It would be good to get a more accurate Sarin angle report rather than the rounded %'s and run it on HCA

What about a girdle that is rated MD-STK..is that too thick?

Assuming all things being equal, are diamonds with THIN-MD girdle or MD girdle more expensive than MD-STK?

Just wanted to thank everone for their input.

hi,


medium to slightly thick is fine.


the first stone you mentioned is also fine.


unlike cut nut, i would NOT recommend setting it there where girdle is very thin; that would only increase the risk of breaking.


i would like to advise to buy the first stone and inform the setter to be careful for some girdle areas are vtn.


good luck,
