This 2.5ct lab-grown cushion sits in the two to three carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG647492596 or 647492596. Listed at 4 retailers as of October 30, 2026, with prices from $2,335 to $10,891, a $8,556 spread on the same certified stone. Zales lists it at $10,891. 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.
