This 1.25ct lab-grown marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG800656300 or 800656300. Listed at 4 retailers as of October 28, 2026, with prices from £825 to £1,157, a £331 spread on the same certified stone. Kay Jewelers lists it at £1,157. 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.
