About this 3.6ct lab-grown cushion diamond

This 3.6ct lab-grown cushion sits in the three to five carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG605386216 or 605386216. Listed at 10 retailers as of October 31, 2026, with prices from $645 to $2,470, a $1,825 spread on the same certified stone. Brilliant Earth lists it at $2,470. 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.
