This 1.4ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG840629708 or 840629708. Listed at 12 retailers as of October 30, 2026, with prices from €230 to €1,639, a €1,409 spread on the same certified stone. Helzberg Diamonds lists it at €1,639. 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.
