About this 3.05ct lab-grown cushion diamond

This 3.05ct lab-grown cushion sits in the three to five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG843641730 or 843641730. Listed at 15 retailers as of October 31, 2026, with prices from $1,395 to $5,269, a $3,874 spread on the same certified stone. Taylor and Hart lists it at $5,269. 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.
