About this 1.05ct lab-grown cushion diamond

This 1.05ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG840611884 or 840611884. Listed at 16 retailers as of October 25, 2026, with prices from $188 to $1,090, a $902 spread on the same certified stone. Reve Diamonds lists it at $1,090. 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.
