About this 4.01ct lab-grown cushion diamond
This 4.01ct lab-grown cushion sits in the three to five carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included) and certified by GIA. Listed at a single retailer as of October 30, 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.
