well it's no longer available, unless you have it on hold or something. The price seemed OK, but then again I haven't looked. Seems a tad underpriced (maybe)?
Well, I like G VS stones, so you already checked the HCA... next step is to see if one of our vendors (i.e. ID jewelery) can get it in so they can evaluate it for you. You need an IS image to see how well it performs.
Other than that, looks ok for now, needs further investigation.
It looks good on paper, but I pretty much won't buy a diamond from a vendor who doesn't provide a magnified image of the stone and idealscope image. I love G VS1, though!
