About this 1.31ct lab-grown cushion diamond

This 1.31ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG555270518 or 555270518. Listed at a single retailer as of October 31, 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.
