This 1.25ct natural round sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by GIA 7416677910. Listed at 14 retailers as of November 5, 2026, with prices from £1,399 to £3,751, a £2,352 spread on the same certified stone. Diamond Quarter lists it at £3,751. 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.
