About this 2.8ct lab-grown radiant diamond

This 2.8ct lab-grown radiant sits in the two to three carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG685540914 or 685540914. Listed at 2 retailers as of October 26, 2026, with prices from $7,159 to $8,935, a $1,776 spread on the same certified stone. Shane Co lists it at $8,935. 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.
