About this 1.51ct lab-grown cushion diamond

This 1.51ct lab-grown cushion sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG766657558 or 766657558. Listed at 16 retailers as of October 25, 2026, with prices from €216 to €1,056, a €840 spread on the same certified stone. Brilliant Earth lists it at €1,056. 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.
