About this 1.25ct lab-grown radiant diamond

This 1.25ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG681504549 or 681504549. Listed at 16 retailers as of November 4, 2026, with prices from $271 to $1,757, a $1,486 spread on the same certified stone. Flawless Fine Jewelry lists it at $1,757. 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.
