Hi folks, I wanted your opinions on this unbranded H&A stone. Here are the specs. 2.02 RB H&A SI G 61.8 Total Depth 55.9 Table 34.9 CA 40.6 PA for approx 17k. Is this a good deal assuming this stone is eye clean? Thanks in Advance

Maybe it is.... But you should get more information, besides "numbers". Most consumers believe that good numbers equate with good or better light performance. This may or may not be true. Have it checked out by a professional gemologist /appraiser. No sense gambling with 17K. Rockdoc

Hey Swan, a couple of questions- Is it an SI1 or SI2? What lab did the grading report? What are the diameter measurements? Girdle thickness? Culet size? Symmetry and polish? Fluorescence? Thanks, Rich, Independent GG Appraiser |

Opps rookie mistake. The stone is a SI-1 . GIA CERT Girdle - medium to slighlty thick Symmetry - EX Polish - EX Diameter - 8.08 - 8.13 X 5.01 Fluroscence - None Culet - None from the face up position there is a cloud on the table and 2 small feathered spots. From the rear there is 2 small needle inclusions on the edges. Thanks for the input! --------------------------- |

Hi Swan. Thanks for the additional info. This should be a very nice stone. The conservative GIA grading probably assures you of an eyeclean SI1, and the excellent symmetry and excellent polish indicate a stone that a diamond cutter went to a lot of trouble with. An ideal make AGS "0", or AGA "1B", the diamond is priced very reasonably for a bricks & mortar store and reasonably for an internet purchase. You don't happen to have a full faceup view of the diamond do you? It helps when tweaking the DiamCalc image as close as possible to the subject stone. I've ran the profile through with a "middle of the road" set of star facet and lower girdle facet lengths. If your stone varies much from these, the following Light Return Analysis will as well. But in all probability you've got a gorgeous stone there. Light Return (mono)…...: 0.99 Very Good Light Return (stereo)…..: 0.96 Very Good (Non) Leakage (mono)..: 0.97 Very Good (Non) Leakage (stereo).: 0.97 Very Good Contrast............................: 0.98 Very Good (Non) FishEye Effect…...: 1.00 Very Good ----------- IdealScope- In general, the darker pink areas indicate areas of greater light return, with the lighter pink areas indicating areas of lesser light return. The black areas indicate areas of greater contrast, with the gray areas indicating areas of lesser contrast. The white areas indicate areas of light leakage. A good explanation of the IdealScope image along with examples can be found at http://www.pricescope.com/idealscope_indx.asp Disclaimer- The facet arrangement and symmetry of the image will probably vary from your actual diamond, which may affect the light performance indicated. The computer generates an image with “perfect” symmetry, which is rare. Also, the star/lower girdle facet lengths may be different from your diamond. The computer simulation is reproduced best when the actual diamond is being viewed and the image "tweaked" to the appearance of the diamond, or Sarin info is downloaded directly into the program. However, this "blind" reproduction should be helpful in considering the major light performance aspects.. ----------- Rich, Independent GG Appraiser |

WoW...Thanks for the lengthy research on this stone. I don't have an image of it to share. I guess it's time to make a decision soon. --------------------------- |
