About this 0.71ct lab-grown cushion diamond

This 0.71ct lab-grown cushion sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included) and certified by IGI LG649458726 or 649458726. 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.
