This 0.61ct lab-grown cushion sits in the half to three-quarter carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG660409134 or 660409134. Listed at 4 retailers as of October 30, 2026, with prices from £237 to £569, a £331 spread on the same certified stone. Riddles Jewelry lists it at £569. 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.
