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 LG668447661 or 668447661. Listed at 25 retailers as of November 2, 2026, with prices from €152 to €1,462, a €1,310 spread on the same certified stone. Do Amore Diamonds lists it at €1,462. 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.
