This 1.7ct lab-grown oval sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG442066215 or 442066215. Listed at 12 retailers as of October 31, 2026, with prices from €841 to €4,201, a €3,360 spread on the same certified stone. MOH London lists it at €4,201. 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.
