About this 1.03ct natural oval diamond

This 1.03ct natural oval sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1543127758. Listed at 14 retailers as of November 4, 2026, with prices from £1,845 to £3,606, a £1,760 spread on the same certified stone. MOH London lists it at £3,606. 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.
