About this 1.27ct natural oval diamond

This 1.27ct natural oval sits in the one-and-a-quarter to one-and-a-half carat band, graded M colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2235594540. Listed at 12 retailers as of November 5, 2026, with prices from £1,478 to £3,823, a £2,345 spread on the same certified stone. NZ Jewellers lists it at £3,823. 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.
