polished girdle decreasing colour grading

[mike2]

Mr. Diamond dealer told my " lady" and I that polishing the girdle on a round I stone, changes the grading in some way?
How does this work? and do we want a polished or rough, non polished girdle?

That is the most absurd information I've ever heard.

Girdles come in 2 flavors. Faceted or bruted. The finish on a girdle has absolutely no bearing on it's beauty or value and some of the finest most rare cuts in the world have either bruted girdles or faceted girdles. If you've narrowed down a stone that is to your liking and the girdle is bruted instead of faceted don't let a silly thing like that discourage your decision. Same holds if the girdle was faceted and you wanted it bruted.

What should concern you way more than that is if the girdle is too thin or too thick and it's symmetry (wavy or straight) and even more importantly it's cut quality.

Hope that helps.

Peace,

Hi Mike 2,
This is a perfect example that not every "Diamond dealer" is a diamond dealer,... I am thinking maybe there was a differnt girdle on his mind,... You know,.. 3rh floor ladies lingerie?! Yes that's what I meant,...
I would not let your lady see this guy again,...

Polished girdles, frosted girdles, and faceted girdles
will not effect the price, but, it would not surprise me
in the least if some people have a preference.

I've heard it said that a "frosted" girdle can sometimes very slightly help make a stone look a nuance whiter (because of the introduction of "white" into the interior of the stone from inner girdle reflections), but I've yet to see anything that confirms this.

Has anyone had any experience with this? A diamond cutter would be a good one to ask.

Also, a poor bruting job (usually done too rapidly) is sometimes covered up by polishing or faceting the girdle. Evidence of the poor job sometimes remains in the form of minute or significant "bearding", which would affect the clarity grade.

I remember reading that a fine frosted (bruted) girdle is more difficult to create than a polished or faceted girdle. A "lost art" so to speak. Does anyone have any knowledge in this regards?

I vaguely remember that Marty Haske wrote something in the past about polished girdles possibly having a negative impact on apparent color due to dirt and metal fragment buildup.

I'm sure it must be more difficult for the average person to keep a polished/bruted girdle clean than a faceted one.

Personally, I prefer faceted - it's just more esthetically pleasing.
