About this 3.03ct lab-grown cushion diamond

This 3.03ct lab-grown cushion sits in the three to five carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG851645735 or 851645735. Listed at 9 retailers as of November 3, 2026, with prices from €1,243 to €4,664, a €3,421 spread on the same certified stone. Taylor and Hart lists it at €4,664. 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.
