    How can I determine cut on these stones if there is no Sarin report? I am not sure if there is one yet. If u had to choose a stone, what would u use to determine choice? What if this was your only information to go by? Thanks in advance!

    1.51 G SI1 GIA $9,916 61.7 56 EX EX None 7.37x7.41x4.56

    1.52 F SI1 GIA $10,065 61.8 58 VG VG None 7.33x4.52

    1.51 G SI1 GIA $9,671 61.9 58 VG VG None 7.35x7.39x4.56

    1.53 G SI1 GIA $9,670 60.9 57 VG VG None 7.42x7.52x4.55

    first of all, all of these diamonds show lower prices on pricescope.
    1.51 G SI1 61.7% 56% GIA no ex ex no $9814
    1.52 F SI1 61.8% 58% GIA m-tk f no vg vg no 7.33x4.52 $9589 cash/$9785 credit
    1.51 G SI1 61.9% 58% GIA m-stk no vg vg no 7.35x7.39x4.56 $9214 cash/$9402 credit
    1.53 G SI1 60.9% 57% GIA t-m no vg vg no 7.42*7.52*4.55 $9571
    Secondly, there are vendors out there that can get you a sarin. DiamondBrokersofFl.com can get most all of the pricescope stones, and will match their price. Plus they'll run a brilliancescope report along with the sarin.
    also, here's a 1.52ct F SI2 SuperbCert in your price range
    http://search.virtcert.com/cgi/u/1063/v.cgi?stock=289679&_s=1063&_p=htj8766&_c=&_fs=1&prestock=
    so to answer your question, which one would i choose based on only this information? none of them. i'd choose the superbcert. but if you had the sarin information along with a brilliancescope for those other stones...well that would be a different story :)
    but that's just me.
    the experts on this board are a lot smarter than me, they'll be able to give you better advice.

    Buttercup, most internet brokers can get Sarin or Ogi report for the listed stones - some have the machines in house (Whiteflash, GoodOldGold, Blue Nile, Mondera) other just need to call a supplier/cutter. :)

    Brilliancescope: Although it measures something, there are still many questions about its ability to represent appearance of the diamonds correctly. For example EightStar diamonds do not have the best results with Brilliancescope. Make a search here for Brilliancescope to read previous discussions on this subject.

    Thanks. So, I guess I could get one of those stones listed and it could be "dead," huh? This is what makes net shopping like detective work. SO, u guys would feel comfortable purchasing a stone (as I listed) if the Sarin report shows what? Could you give me a range of what is considered good to excellent (or a link to read on). Thanks!:read:

    play with HCA
    it is not that simple
    but try shallower than 34.5 and 40.8 degrees and around 55-58% table

    So, it is not a good idea to buy a stone without that Sarin report, huh? I appreciate the info on this.
