About this 1.05ct lab-grown cushion diamond

This 1.05ct lab-grown cushion sits in the classic one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG665403357 or 665403357. Listed at 11 retailers as of October 30, 2026, with prices from $266 to $1,620, a $1,354 spread on the same certified stone. Do Amore Diamonds lists it at $1,620. 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.
