About this 0.89ct lab-grown radiant diamond

This 0.89ct lab-grown radiant sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG818658787 or 818658787. Listed at 13 retailers, with prices from $258 to $1,290 at Reve Diamonds, a $1,032 spread on the same certified stone. 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.
