About this 1ct lab-grown radiant diamond

This 1ct lab-grown radiant sits in the classic one-carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG845617574 or 845617574. Listed at 3 retailers as of November 4, 2026, with prices from $420 to $1,154, a $734 spread on the same certified stone. Frank Darling lists it at $1,154. 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.
