About this 3.05ct lab-grown cushion diamond

This 3.05ct lab-grown cushion sits in the three to five carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG739586190 or 739586190. Listed at 17 retailers as of October 27, 2026, with prices from €477 to €3,785, a €3,308 spread on the same certified stone. Queensmith lists it at €3,785. 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.
