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 LG654455718 or 654455718. Listed at 2 retailers as of October 31, 2026, with prices from $299 to $1,366, a $1,068 spread on the same certified stone. Diamond Quarter lists it at $1,366. 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.
