This 1.72ct lab-grown oval sits in the one-and-a-half to two carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG726523948 or 726523948. Listed at 25 retailers as of October 31, 2026, with prices from £258 to £2,120, a £1,861 spread on the same certified stone. Brilliant Earth lists it at £2,120. 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.
