About this 1.7ct lab-grown cushion diamond

This 1.7ct lab-grown cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG591302215 or 591302215. Listed at 12 retailers as of November 3, 2026, with prices from $363 to $1,449, a $1,086 spread on the same certified stone. Brilliance lists it at $1,449. 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.
