About this 0.67ct lab-grown radiant diamond

This 0.67ct 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 LG712578195 or 712578195. Listed at 19 retailers as of October 29, 2026, with prices from $139 to $1,128, a $989 spread on the same certified stone. Flawless Fine Jewelry lists it at $1,128. 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.
