About this 1.39ct lab-grown cushion diamond

This 1.39ct 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 LG766669628 or 766669628. Listed at 7 retailers as of October 29, 2026, with prices from $1,715 to $5,288, a $3,573 spread on the same certified stone. Michael Trio lists it at $5,288. 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.
