This 1.71ct lab-grown oval sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG445039705 or 445039705. Listed at 9 retailers as of October 29, 2026, with prices from £702 to £3,254, a £2,552 spread on the same certified stone. MOH London lists it at £3,254. 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.
