About this 0.51ct lab-grown cushion diamond

This 0.51ct lab-grown cushion 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 and certified by IGI LG747589323 or 747589323. Listed at 23 retailers as of October 30, 2026, with prices from €206 to €1,763, a €1,557 spread on the same certified stone. Do Amore Diamonds lists it at €1,763. 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.
