About this 1.07ct lab-grown oval diamond

This 1.07ct lab-grown oval sits in the classic one-carat band, graded G colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG677514083 or 677514083. Listed at 4 retailers as of November 3, 2026, with prices from £150 to £691, a £541 spread on the same certified stone. The Diamond Guys lists it at £691. 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.
