About this 0.51ct natural oval diamond

This 0.51ct natural oval sits in the half to three-quarter carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI 738514933. Listed at 7 retailers as of October 30, 2026, with prices from €572 to €1,795, a €1,223 spread on the same certified stone. NZ Jewellers lists it at €1,795. 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.
