About this 0.34ct lab-grown radiant diamond

This 0.34ct lab-grown radiant sits in the sub-half-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG816658164 or 816658164. Listed at 16 retailers as of October 29, 2026, with prices from £121 to £851, a £730 spread on the same certified stone. Zales lists it at £851. 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.
