About this 0.78ct lab-grown oval diamond

This 0.78ct lab-grown oval sits in the just-under-one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG749541658 or 749541658. Listed at 15 retailers as of November 1, 2026, with prices from £105 to £717, a £612 spread on the same certified stone. Reve Diamonds lists it at £717. 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.
