About this 1.6ct lab-grown cushion diamond

This 1.6ct 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 LG687559354 or 687559354. Listed at 10 retailers as of October 31, 2026, with prices from $391 to $2,134, a $1,743 spread on the same certified stone. Taylor and Hart lists it at $2,134. 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.
