About this 0.97ct lab-grown round diamond

This 0.97ct lab-grown round sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG731587707 or 731587707. Listed at 17 retailers as of October 28, 2026, with prices from $319 to $1,901, a $1,582 spread on the same certified stone. Reve Diamonds lists it at $1,901. 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.
