About this 4.05ct lab-grown cushion diamond

This 4.05ct 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 LG547239407 or 547239407. Listed at 12 retailers as of October 31, 2026, with prices from $1,191 to $4,944, a $3,753 spread on the same certified stone. Taylor and Hart lists it at $4,944. 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.
