This 1.6ct lab-grown oval sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG550237331 or 550237331. Listed at 14 retailers as of October 25, 2026, with prices from €443 to €1,343, a €900 spread on the same certified stone. Reve Diamonds lists it at €1,343. 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.
