This 2.6ct lab-grown oval sits in the two to three carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG695514224 or 695514224. Listed at 19 retailers as of October 29, 2026, with prices from £259 to £3,179, a £2,920 spread on the same certified stone. Brilliant Earth lists it at £3,179. 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.
