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 $327 to $2,804, a $2,477 spread on the same certified stone. Do Amore Diamonds lists it at $2,804. 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.
