About this 3ct lab-grown radiant diamond

This 3ct lab-grown radiant sits in the three to five carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included) and certified by IGI LG570351531 or 570351531. Listed at a single retailer as of October 31, 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.
