About this 0.51ct natural oval diamond

This 0.51ct natural oval sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 1535877768. Listed at 6 retailers as of October 28, 2026, with prices from $1,059 to $1,678, a $619 spread on the same certified stone. 77 Diamonds lists it at $1,678. Flawless clarity in sub-one-carat stones is rarely visible to the naked eye over VS1, so you are paying a meaningful premium for grade rather than appearance.
