About this 1.05ct lab-grown cushion diamond

This 1.05ct lab-grown cushion sits in the classic one-carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG643449231 or 643449231. Listed at 10 retailers as of November 1, 2026, with prices from $442 to $1,198, a $756 spread on the same certified stone. MOH London lists it at $1,198. 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.
