About this 0.51ct lab-grown princess diamond

This 0.51ct 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 LG844629976 or 844629976. Listed at 23 retailers as of October 30, 2026, with prices from $168 to $1,092, a $924 spread on the same certified stone. Reve Diamonds lists it at $1,092. 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.
