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 4, 2026, with prices from $349 to $2,704, a $2,355 spread on the same certified stone. Do Amore Diamonds lists it at $2,704. 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.
