About this 0.45ct lab-grown cushion diamond

This 0.45ct lab-grown cushion sits in the sub-half-carat band, graded E colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG656478050 or 656478050. Listed at 5 retailers as of October 29, 2026, with prices from $316 to $700, a $384 spread on the same certified stone. Riddles Jewelry lists it at $700. 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.
