About this 2.5ct natural oval diamond

This 2.5ct natural oval sits in the two to three carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2554507664. Listed at 18 retailers as of October 31, 2026, with prices from £11,739 to £21,415, a £9,677 spread on the same certified stone. MOH London lists it at £21,415. 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.
