About this 0.51ct lab-grown asscher diamond

This 0.51ct 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 LG655445393 or 655445393. Listed at 2 retailers as of October 31, 2026, with prices from $159 to $733, a $574 spread on the same certified stone. Diamond Quarter lists it at $733. 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.
