About this 5.03ct natural oval diamond

This 5.03ct natural oval sits in the over five carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2151528674. Listed at 16 retailers as of November 1, 2026, with prices from £76,043 to £132,346, a £56,303 spread on the same certified stone. MOH London lists it at £132,346. 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.
