Hello diamond gurus! I'm looking for a little guidance. I need to replace a diamond and I have been checking out a few sites out there and reading up on some sarin reports and diamond specs but I am still confused. What is the culet? What is a good culet reading? And, when a sarin reports reads "Fluorescence: NONE" or "Fluorescence: medium blue", is this good, bad? Here is a litte more info: I am looking for a 1.25, G in color, round brilliant cut, VS1. I appreciate any guidance. Jamie |

Hi Jtastor, Have you seen our tutorial www.pricescope.com/tutorial.asp ? Medium and smaller culet are ok. Larger culet is considered as negative factor since you'll be able to see it from the top of the stone. See for details www.pricescope.com/tutor_culet.asp . As for fluorescence, you can find an answer here: http://www.pricescope.com/tutor_fluor.asp . Mainly you should make sure that the stone doesn't look oily or cloudy under the bright light. Hope it helps |

A Sarin device does not grade UV Fluorescence. Someone using the machine has given that grade which may or may not be accurate. It is a subjective opinion, not created on a Sarin. Be a bit cautious if you have not been properly advised by the seller in this matter. Many diamonds have a pointed culet today,which simply means they have no tiny facet at the bottom tip of the stone. The culet helpts to prevent a small chip from developing at this point. Since absence of a culet does not hurt the light return it is not a big consideration in cut quality. You are best off with a small culet rather than none, but it is no big deal. ------------------ |

Oldminer, thanks for pointing out about fluorescence and Sarin report. It was also seemed strange to me but I thought maybe there is a confusion with the lab report. |

You folks are so helpful...I didn't mean to confuse you ...I don't really know if I saw the fluorescence grading in the Sarin report or just a specs document about the different diamonds I was looking at...all I know is that after talking with a number of jewelers and hearing about culet, girdle, the 4Cs, crown, etc, I got all confused as to which characteristics were the very most important (now I know). Thank you oldminer and leonid for clearing things up for me. Leonid: I will definitley make sure to run the stone I find through the cut adviser. Jamie |
