About this 4.09ct lab-grown cushion diamond

This 4.09ct lab-grown cushion sits in the three to five carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG849659608 or 849659608. Listed at 17 retailers as of October 31, 2026, with prices from $844 to $10,421, a $9,577 spread on the same certified stone. Brilliant Earth lists it at $10,421. 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.
