About this 1.72ct lab-grown cushion diamond

This 1.72ct lab-grown cushion sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG478111645 or 478111645. Listed at a single retailer as of October 29, 2026. If it later appears at another store, Carat Hunter will surface the price comparison automatically. 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.
