    Hello PS community,

    I posted on the wrong thread so I'm posting it here again. Can I get help on getting some feedback on some stuff I was looking at. I wanted a lab grown diamond around 3 carats with at least g color, eye clean, good cut, and nothing with a number 4 in the carat weight.

    I don't know if this is worth the price difference....

    These are the ones I wanted to get some feedback on or if you guys can point me to ones that might be better. Thank you!

    You can run the stones' measurements/angles through the HCA tool (under the Tools tab at the top) to check if they come under or around a score of 2 (which is what you are looking for). If they come in under 2(ish) it suggests the angles work well together and they should perform well.

    I'm not sure if you might only be limited to a few assessments, though, so do your preferred choices first.

    Thanks for your reply. I did run the HCA tool and three are between 1 and 2. The most expensive one I probably will weed out due to the price and the HCA score is 2.5. The other one that is 3.01 from BE is HCA 2.3 and I'm not sure if its considered hearts and arrows. I wanted to see if anyone can provide any insights other than the HCA tool.

    So we have:

    3.08 G VS2 $16,473
    3.16 G VS2 $19,200
    3.07 G VS1 $21,430
    3.01 G VS2 $19,840
    3.22 G VS1 $26,080

    You can see from that list the current issue that MMDs are priced all over the place for similar specs, so much so that it is hard to work out what is good value, what is expensive, and what is 'cheap for a reason'! :(

    As you say, the most expensive one can be ruled out due to the price, I would say. (That is a BIG jump in cost.)

    I am a clarity freak :razz: so the VS2s with dark inclusions make me twitch a bit... lol... hence I would prefer the VS1s if I was buying for myself. (But my taste is not your taste!)

    I am confused how the 3.16 can have an 'Ideal' cut grade on the site but only have 'very good' symmetry. That said, it has a small table and a high crown (relative to the PS-recommended parameters for Modern Round Brilliant diamonds) so should tend towards coloured fire rather than white light (which I prefer myself). The inclusions on the grading report are visible in the video (in which the stone is rotated about 120 degrees clockwise from the grading report) but then it is highly magnified and the inclusions are towards the edge of the stone so more easily 'lost' within the sparkle.

    I'm not sure if the 3.07 is very 'crisp'? or whether it is the video being slightly out of focus. I'm also not sure if you can see 'stria' (sort of 'layering') reflecting on some of the pavilion facets at some angles - this has been noted as potentially reducing performance in CVD MMDs.

    The 3.08 looks very clean for a VS2 (although the video is much smaller and harder to see). It might have more white light than coloured fire due to the table at the larger end of the PS-recommended scale. It is by far the cheapest though!


    Not sure any of that helps?! lol
