About this 4.12ct lab-grown cushion diamond

This 4.12ct lab-grown cushion sits in the three to five carat band, graded J colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG665402646 or 665402646. Listed at 9 retailers as of October 31, 2026, with prices from €828 to €5,129, a €4,301 spread on the same certified stone. Do Amore Diamonds lists it at €5,129. 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.
