About this 1.03ct natural oval diamond

This 1.03ct natural oval sits in the classic one-carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2121831817. Listed at 5 retailers as of November 1, 2026, with prices from £1,561 to £2,944, a £1,383 spread on the same certified stone. MOH London lists it at £2,944. 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.
