About this 1.29ct lab-grown cushion diamond

This 1.29ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG551211429 or 551211429. Listed at 11 retailers as of November 1, 2026, with prices from $445 to $2,280, a $1,835 spread on the same certified stone. Do Amore Diamonds lists it at $2,280. 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.
