About this 0.66ct lab-grown radiant diamond

This 0.66ct 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 LG712559465 or 712559465. Listed at 25 retailers as of November 1, 2026, with prices from $190 to $1,640, a $1,450 spread on the same certified stone. Do Amore Diamonds lists it at $1,640. 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.
