This 3.51ct lab-grown cushion sits in the three to five carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG828615267 or 828615267. Listed at 12 retailers as of November 1, 2026, with prices from $1,117 to $5,210, a $4,093 spread on the same certified stone. Do Amore Diamonds lists it at $5,210. 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.
