About this 4.51ct lab-grown cushion diamond

This 4.51ct lab-grown cushion sits in the three to five carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG828610402 or 828610402. Listed at 11 retailers as of October 29, 2026, with prices from $2,021 to $6,605, a $4,583 spread on the same certified stone. MOH London lists it at $6,605. 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.
