About this 1.83ct lab-grown cushion diamond

This 1.83ct lab-grown cushion sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG591309859 or 591309859. Listed at 6 retailers as of October 30, 2026, with prices from $440 to $2,011, a $1,571 spread on the same certified stone. Michael Trio lists it at $2,011. 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.
