About this 1.2ct natural oval diamond

This 1.2ct natural oval sits in the classic one-carat band, graded M 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 2556614941. Listed at 6 retailers as of November 4, 2026, with prices from £755 to £1,172, a £417 spread on the same certified stone. Wholesale Diamonds Direct lists it at £1,172. 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.
