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 LG770669329 or 770669329. Listed at 19 retailers as of October 29, 2026, with prices from $209 to $1,958, a $1,749 spread on the same certified stone. MOH London lists it at $1,958. 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.
