About this 3.09ct lab-grown cushion diamond

This 3.09ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG544281289 or 544281289. Listed at 12 retailers as of October 29, 2026, with a 279% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
