This 1.45ct 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 standard cut grade and certified by IGI LG617452366 or 617452366. Listed at 8 retailers as of October 28, 2026, with prices from $231 to $1,880, a $1,649 spread on the same certified stone. Do Amore Diamonds lists it at $1,880. 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.
