About this 4.03ct lab-grown asscher diamond

This 4.03ct lab-grown asscher sits in the three to five carat band, graded F colour (colourless) and SI1 clarity (slightly-included) and certified by IGI LG668449672 or 668449672. 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.
