About this 1.43ct lab-grown cushion diamond

This 1.43ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG620416774 or 620416774. Listed at 6 retailers as of October 29, 2026, with prices from $453 to $1,175, a $722 spread on the same certified stone. MOH London lists it at $1,175. 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.
