About this 0.97ct lab-grown oval diamond

This 0.97ct lab-grown oval 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 LG598303690 or 598303690. Listed at 24 retailers as of October 29, 2026, with prices from $373 to $2,150, a $1,777 spread on the same certified stone. Brilliant Earth lists it at $2,150. 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.
