About this 1.03ct lab-grown radiant diamond

This 1.03ct lab-grown radiant sits in the classic one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG605312121 or 605312121. Listed at 17 retailers as of November 1, 2026, with prices from $251 to $1,944, a $1,693 spread on the same certified stone. Do Amore Diamonds lists it at $1,944. 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.
