allygirl Cut Rock Total Posts: 196 Last Post: 11/5/2006 Member Since: 7/19/2006	Okay, last question but I posted with this topic because I was concerned that my old topic was getting less responses. I just looked at the certificate for a diamond I am interested in. I believe at the culet it states VERY SMALL where all the other certificates states pointed. I went on a website and from what I could read, it stated that very small is better because it won't chip?? Sound right? Also, what numbers are shown by the giirdle? What should they be for a 1.5 carat round?

If it's an AGS0 though shouldn't that mean that it is a good diamond anyway!? That would bother me if I could see the white dot to the naked eye. Is it DEFINITE that with a very small culet you will see that ? Would this make you decide against a diamond if EVERY other specific is perfect!!?

It is nothing to worry about; it is actually a negligible factor in choosing a diamond. By definition, culets up to medium are only seen under magnification. _____________ Omnia Mea Mecum Porto.

allygirl Cut Rock Total Posts: 196 Last Post: 11/5/2006 Member Since: 7/19/2006	So, a pointed culet is what? If it is closer to none, I don't get it at all. If it is pointed, then shaved/cut down to be none, than isn't VERY SMALL in between POINTED and NONE?????

Scott 00 Cut Rock Total Posts: 278 Last Post: 4/13/2007 Member Since: 5/27/2004	Pointed and "none" are the same. Very small is HIGHLY unlikely to be seen with the naked eye. Traditionally culets were to ensure that the tip wouldnt chip as you said, and it is my understanding that this was because stones used to be set lower i.e. the culet sometimes touching skin. These days with typical 4-6 prong Tiffany designs its not a big deal (danger of chippage) so a pointed culet became standard. Either way, its not a big deal, if you think the stone is pretty, and you like the price etc, go for it, the culet isnt an issue at this size. Personally my diamond has a "medium culet" and it is visible to me and that is a good thing, since due to the cut of my stone (old mine cut cushion), the culet helps me see the repeating patterns of the pavillion better! Good luck

Think of it like this... the culet is the 58th facet and is parallel to the table. If the culet area is pointed then there is no culet. very small, small etc mean that there IS a 58th facet or culet but you still can't see it. mine is 'sl large' and you can only see it with the naked eye if you're holding the stone, unset, up to a light source. In pictures though it is pretty big because they're so magnified.

Pyramid Ideal Rock Total Posts: 2,914 Last Post: 11/11/2009 Member Since: 11/10/2002	So does a 'very small' culet show as a white dot, I thought it would be polished like a facet???

Capitol Bill Cut Rock Total Posts: 187 Last Post: 9/16/2006 Member Since: 6/7/2005	No worries with the very small culet. As mentioned above, the grading report is just acknowledging that there is actually a culet facet (58 facets rather than 57). Diamonds with culets used to be the norm. The culet makes the stone a bit more durable when being handled loose. I sometimes wish there would be more diamonds with culet facets because on occasion I've had to reject stones whose "pointed" culets showed signs of damage from improper or rough handling (damage you can't see with the naked eye). With magnification you'll see the culet facet as a white dot only if there is white light or a white surface behind it. Because the culet and the table are parallel they form a window so you can see through the stone, albeit only with significant magnification. Bill Scherlag IceMine.com

allygirl Cut Rock Total Posts: 196 Last Post: 11/5/2006 Member Since: 7/19/2006	Thanks for all of that information Bill! So basically you prefer to have a small or very small culet as opposed to a pointed? I just thought it odd that I had never seen anything besides "pointed" or "none". Now, if I could only learn what to expect about the girdle....

Cehrabehra Sorry I was thinking that you meant the culet was white because it had been left as rough diamond rather than polished.

So basically you prefer to have a small or very small culet as opposed to a pointed? Not at all. I really have no preference. As long as the culet is not a distraction, there are many more important factors about the stone to consider. I just thought it odd that I had never seen anything besides 'pointed' or 'none'. 57-facet stones are pretty much the norm nowadays. Now, if I could only learn what to expect about the girdle....
