About this 1.8ct lab-grown cushion diamond

This 1.8ct lab-grown cushion sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG601395034 or 601395034. Listed at 16 retailers as of November 1, 2026, with prices from $488 to $2,163, a $1,675 spread on the same certified stone. MOH London lists it at $2,163. 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.
