About this 0.7ct lab-grown oval diamond

This 0.7ct lab-grown oval sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG836619164 or 836619164. Listed at 19 retailers as of October 29, 2026, with prices from £196 to £999, a £802 spread on the same certified stone. Helzberg Diamonds lists it at £999. 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.
