About this 1.27ct lab-grown oval diamond

This 1.27ct lab-grown oval sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG605378799 or 605378799. Listed at 16 retailers as of November 4, 2026, with prices from €217 to €1,355, a €1,138 spread on the same certified stone. Taylor and Hart lists it at €1,355. 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.
