About this 2.92ct lab-grown radiant diamond

This 2.92ct lab-grown radiant sits in the two to three carat band, graded F colour (colourless) and SI1 clarity (slightly-included) and certified by IGI LG668418632 or 668418632. Listed at a single retailer as of November 2, 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.
