About this 3.1ct lab-grown asscher diamond

This 3.1ct lab-grown asscher sits in the three to five carat band, graded E colour (colourless) and SI1 clarity (slightly-included) and certified by IGI LG687529292 or 687529292. Listed at a single retailer as of October 28, 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.
