About this 3.43ct lab-grown cushion diamond

This 3.43ct lab-grown cushion sits in the three to five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG603358565 or 603358565. Listed at 12 retailers as of October 29, 2026, with prices from $548 to $4,350, a $3,802 spread on the same certified stone. Do Amore Diamonds lists it at $4,350. 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.
