About this 1.71ct lab-grown oval diamond

This 1.71ct lab-grown oval sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG840627299 or 840627299. Listed at 15 retailers as of October 26, 2026, with prices from £173 to £874, a £701 spread on the same certified stone. Brilliance lists it at £874. 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.
