any advantage in light return for a stone with faceted girdle vs...

[Dancing Fire]

a stone with polished or bruted girdle?

 

[karenleah15]

All the info I have seen on this topic say there is no difference in light return. BUT.....I have a faceted girdle and wearing a diamond on my finger you end up looking at it from all directions. I often see beautiful light return off the girdle (there is a section of my girdle that is slightly thick.) If I had a choice between faceted and non I would choose faceted.

An interesting and possibly important question. I''ve never seen any studies on this, only anecdotal comments.

Personally, I do not like the look of a polished or, in particular, a bruted girdle. Furthermore, I suspect that a bruted girdle will accumulate difficult to remove dirt making the girdle appear gray, far more easily and often than a faceted one.

Just how large and exactly what kind of light return effects dirt has on all girdle finishes, I don''t know, but it wouldn''t be rocket science to do some experiments to find out...the science of shmutz!

Mine is faceted and I think it''s awesome.

What''s a bruted girdle???

 

[mrssalvo]

A bruted girdle would be one that is not polished or faceted.

and kaleigh, i just did a search b/c i didn't know either

 

[oldminer]

Girdle thickness (width) plays a larger role in overall appearance and performance than how the girdle is cut, faceted, polished or bruited. Predicting how the girdle will affect appearance is pretty much going to be inaccurate as there are so many variables and who knows which ones are of importance?

We can measure light performance directly. I wouldn''t begin to guess how girdle thickness would alter light return. There are so many ways to improve or diminish light return, that a stone with a thick girdle which we''d generally suspect of hurting performance might well perform better than a stone with a medium girdle that had some other cut faults.....

Faceted or polished girdles, at one time, were symbolic of extra care in cutting, but are often now on rather poorly cut stones, too.

What''s a bruted girdle???

i think

that''s when a woman tries to squeeze into a smaller size girdle and it feels brutal.

OMG, Df!!!!
I just started cracking up when I read that, too funny for words. Oh and mrssalvo, I am very impressed!!!! I honestly have never heard that term before and worked for a high end jewelry store. I have learned more on PS, than all my years working, and the nicest thing is that the information is FREE!!!!

 

[Kaleigh]

Ok for all you diamond experts why would anyone want a girdle that is bruted????

Besides the kind of girdle that DF is talking about!!!!

That''s an excellent question. It''s also a topic that is often over looked in today''s world of 2C''s diamond buying. A bruted diamond is a diamond with a natural girdle...the "frosty" look comes from the girdling or rounding process where one diamond is forcefully used against the other in a lathe-like fashion. There is no adherance to grain, so there is no polishing like there is in a faceted girdle or a polished girdle, both of which are a result of a different process, both from each other and "bruting".

The girdle has little or no effect on the brilliance of a stone, unless it''s reflection is intended to help out like in a fancy with a very flat bottom angle. However, the girdle DOES have a strong effect on how a diamond appears in the face up position. A thicker natural girdle can make a stone that draws a little color (read I, J, K) face up as a whiter looking stone, while a faceted or polished girdle will enhance the color and make it look darker.

It amazes me that in today''s market, where the buzzword is "performance" that there are obvious situations where in the name of gaining a certain patterning, that there are situations like faceting the girdle on a "J" color stone that does more harm (IMHO) than good.

Fine material, calls for fine cut proportions. For stones that draw a little color, the cut parameters should be altered to make the stone face up better than it really is.

Thanks, DF! Now I have the full explanation.

Ironically it was you who sent me to the link, which sent me to this link.

And that's what I get for asking.

I believe Lynn''s fabulous new J stone has a frosted or "bruted" girdle. Here is the link: Lynn''s New Stone

 

[Kaleigh]

Too funny Lynn, where in PA??

 

[Mara]

My 1.60 J also has a frosted girdle...at first I was kind of like..WHAT IS THAT...but it has no effect on the stone that I can see in terms of making it look ugly...I don''t even notice it in regular viewing since I think it''s ''thin'' on average...and I can see it with the loupe and just find it interesting rather than a good or bad. Up until this point all my other stones have been faceted on the girdle...but I would not hesitate to get a well-cut frosted girdle stone again as long as no areas were ''thick'' or similar. I like thin-med girdles anyway.

Yeah, what SHE said!

And also, just my humble 2 cents, I probably wouldn''t buy a diamond with a "thick girdle" anyway... faceted OR unfaceted!
