About this 1.34ct lab-grown cushion diamond

This 1.34ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG745507855 or 745507855. Listed at 12 retailers as of November 4, 2026, with prices from $404 to $3,200, a $2,796 spread on the same certified stone. Do Amore Diamonds lists it at $3,200. 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.
