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 SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG488147507 or 488147507. Listed at a single retailer as of November 6, 2026. If it later appears at another store, Carat Hunter will surface the price comparison automatically. 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.
