About this 1.38ct lab-grown cushion diamond

This 1.38ct 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 very-good cut grade and certified by IGI LG502194765 or 502194765. Listed at 7 retailers as of November 3, 2026, with prices from $1,784 to $6,828, a $5,044 spread on the same certified stone. Taylor and Hart lists it at $6,828. 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.
