About this 3.12ct natural oval diamond

This 3.12ct natural oval sits in the three to five carat band, graded G 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 1528131075. Listed at 5 retailers as of November 5, 2026, with prices from £27,583 to £34,515, a £6,932 spread on the same certified stone. Yorxs lists it at £34,515. 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.
