About this 0.54ct lab-grown asscher diamond

This 0.54ct lab-grown asscher sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG621480451 or 621480451. Listed at 21 retailers as of November 1, 2026, with prices from $291 to $1,919, a $1,627 spread on the same certified stone. Reve Diamonds lists it at $1,919. 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.
