This 0.66ct lab-grown radiant sits in the half to three-quarter carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG655421608 or 655421608. Listed at 21 retailers as of November 2, 2026, with prices from €123 to €802, a €679 spread on the same certified stone. Flawless Fine Jewelry lists it at €802. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
