About this 1.87ct lab-grown cushion diamond

This 1.87ct lab-grown cushion sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included) and certified by IGI LG642496889 or 642496889. Listed at a single retailer as of October 27, 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.
