About this 0.34ct lab-grown oval diamond

This 0.34ct lab-grown oval 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 LG816662594 or 816662594. Listed at 13 retailers as of October 29, 2026, with prices from £94 to £687, a £593 spread on the same certified stone. Kay Jewelers lists it at £687. 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.
