This 2.09ct lab-grown round sits in the two to three carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI LG451055630 or 451055630. Listed at 10 retailers as of October 29, 2026, with prices from €904 to €6,270, a €5,366 spread on the same certified stone. MOH London lists it at €6,270. 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.
