I noticed that there is a diamond on Whiteflash site which has come down in price by $5000 dollars. As the price charts here show no change in that carat weight, does this mean the changes are to do with clarity, thing or color perhaps. Just wondering how all the pricing works, I suppose anyone can charge anything they want. Not looking to buy just interested to know. If it the 2.07 F VVS2 ACA.
