About this 0.51ct lab-grown cushion diamond

This 0.51ct 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 standard cut grade and certified by IGI LG691513964 or 691513964. Listed at 6 retailers as of October 30, 2026, with prices from €132 to €570, a €438 spread on the same certified stone. Riddles Jewelry lists it at €570. 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.
