This 3.46ct lab-grown cushion sits in the three to five carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG578320717 or 578320717. Listed at 5 retailers as of October 26, 2026, with prices from $1,391 to $6,281, a $4,890 spread on the same certified stone. Do Amore Diamonds lists it at $6,281. 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.
