This 1.25ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG843638890 or 843638890. Listed at 13 retailers as of November 4, 2026, with prices from $404 to $1,903, a $1,500 spread on the same certified stone. Do Amore Diamonds lists it at $1,903. 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.
