About this 4.17ct lab-grown cushion diamond

This 4.17ct lab-grown cushion sits in the three to five carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG605305138 or 605305138. Listed at 11 retailers as of October 31, 2026, with prices from $560 to $2,588, a $2,028 spread on the same certified stone. MOH London lists it at $2,588. 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.
