About this 1.05ct lab-grown cushion diamond

This 1.05ct lab-grown cushion sits in the classic one-carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG642419220 or 642419220. Listed at 16 retailers as of November 1, 2026, with prices from $298 to $1,638, a $1,341 spread on the same certified stone. Reve Diamonds lists it at $1,638. 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.
