About this 0.54ct lab-grown radiant diamond

This 0.54ct lab-grown radiant sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG747578256 or 747578256. Listed at 20 retailers as of October 29, 2026, with prices from $185 to $1,001, a $816 spread on the same certified stone. Reve Diamonds lists it at $1,001. 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.
