About this 1.5ct lab-grown round diamond

This 1.5ct lab-grown round sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG260000088994 or 260000088994. Listed at a single retailer as of November 1, 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.
