About this 4.51ct lab-grown cushion diamond

This 4.51ct lab-grown cushion sits in the three to five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG826610223 or 826610223. Listed at 9 retailers as of October 29, 2026, with prices from $2,067 to $6,711, a $4,644 spread on the same certified stone. MOH London lists it at $6,711. 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.
