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 FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG831697399 or 831697399. Listed at 9 retailers as of October 29, 2026, with prices from $379 to $1,354, a $975 spread on the same certified stone. MOH London lists it at $1,354. 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.
