About this 3.05ct lab-grown cushion diamond

This 3.05ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG774651315 or 774651315. Listed at 17 retailers as of October 27, 2026, with prices from $1,211 to $5,356, a $4,145 spread on the same certified stone. Taylor and Hart lists it at $5,356. 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.
