About this 0.51ct lab-grown oval diamond

This 0.51ct lab-grown oval sits in the half to three-quarter carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG844647070 or 844647070. Listed at 8 retailers as of November 1, 2026, with prices from £142 to £604, a £463 spread on the same certified stone. MOH London lists it at £604. 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.
