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 LG810637516 or 810637516. Listed at 20 retailers as of November 1, 2026, with prices from £101 to £1,046, a £946 spread on the same certified stone. MOH London lists it at £1,046. 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.
