About this 0.9ct lab-grown radiant diamond

This 0.9ct 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 LG634480895 or 634480895. Listed at 25 retailers, with prices from $176 to $1,676 at Queensmith, a $1,500 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.
