by JackBauer » Jun 25, 2019 I can find diamonds on places like BlueNile or 77Diamonds which have a HCA score of 0.9 but they don't supply Idealscope or ASET images so there is no guarantee of light performance. For my specs, a diamond like this would cost me around £2400 The alternative is buying something like a Crafted by Infinity, Whiteflash ACA, Brian Gavin Signature but their premium price and also cost for UK import tax and VAT costs would see me paying around £3300. Almost 40% more. What would you do? Is it not possible to buy a comparable light performing stone from Blue Nile? Is Blue Nile Astor their way of taking out these better performing diamonds, forcing you to pay a premium? Is Astor comparable for the other super ideals? FYI i'm looking for a F colour, VS2, 0.5 to 0.6 carat diamond on a platinum setting.
