About this 3.06ct lab-grown cushion diamond

This 3.06ct lab-grown cushion sits in the three to five carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG692592752 or 692592752. Listed at 19 retailers as of October 29, 2026, with prices from $1,395 to $5,810, a $4,415 spread on the same certified stone. Brilliant Earth lists it at $5,810. 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.
