About this 1.5ct lab-grown cushion diamond

This 1.5ct lab-grown cushion sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG839698501 or 839698501. Listed at 16 retailers as of November 3, 2026, with prices from $752 to $2,329, a $1,577 spread on the same certified stone. With Clarity lists it at $2,329. 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.
