About this 0.5ct lab-grown princess diamond

This 0.5ct lab-grown princess 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 LG818657661 or 818657661. Listed at 22 retailers as of November 1, 2026, with prices from $181 to $1,070, a $889 spread on the same certified stone. Reve Diamonds lists it at $1,070. 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.
