This 1.39ct lab-grown oval sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG780643278 or 780643278. Listed at 15 retailers as of November 1, 2026, with prices from £163 to £1,396, a £1,233 spread on the same certified stone. Do Amore Diamonds lists it at £1,396. 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.
