This 1.7ct lab-grown oval sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG849643488 or 849643488. Listed at 5 retailers as of October 29, 2026, with prices from £375 to £893, a £518 spread on the same certified stone. MOH London lists it at £893. 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.
