About this 1.17ct lab-grown cushion diamond

This 1.17ct lab-grown cushion sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG830620366 or 830620366. Listed at 16 retailers as of November 4, 2026, with prices from $617 to $3,293, a $2,675 spread on the same certified stone. Helzberg Diamonds lists it at $3,293. 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.
