About this 1.35ct lab-grown cushion diamond

This 1.35ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG520200181 or 520200181. Listed at 14 retailers as of November 1, 2026, with prices from $425 to $2,270, a $1,845 spread on the same certified stone. Do Amore Diamonds lists it at $2,270. 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.
