About this 0.97ct lab-grown radiant diamond

This 0.97ct 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 LG817670921 or 817670921. Listed at 21 retailers as of October 30, 2026, with prices from $225 to $1,547, a $1,322 spread on the same certified stone. Brilliant Earth lists it at $1,547. 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.
