About this 0.5ct lab-grown radiant diamond

This 0.5ct lab-grown radiant 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 LG812621980 or 812621980. Listed at 20 retailers as of October 29, 2026, with prices from $214 to $1,983, a $1,770 spread on the same certified stone. MOH London lists it at $1,983. 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.
