About this 0.51ct lab-grown princess diamond

This 0.51ct lab-grown princess sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG812620069 or 812620069. Listed at 21 retailers as of October 30, 2026, with prices from $311 to $1,872, a $1,561 spread on the same certified stone. Reve Diamonds lists it at $1,872. 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.
