About this 1.09ct lab-grown cushion diamond

This 1.09ct lab-grown cushion sits in the classic one-carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG816607773 or 816607773. Listed at 11 retailers as of November 3, 2026, with prices from $1,186 to $5,153, a $3,968 spread on the same certified stone. MOH London lists it at $5,153. 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.
