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 LG803616821 or 803616821. Listed at 17 retailers as of October 29, 2026, with prices from $193 to $1,807, a $1,614 spread on the same certified stone. MOH London lists it at $1,807. 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.
