About this 1.65ct lab-grown radiant diamond

This 1.65ct lab-grown radiant sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included) and certified by IGI LG550236551 or 550236551. Listed at a single retailer as of October 23, 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.
