About this 2.51ct natural oval diamond

This 2.51ct natural oval sits in the two to three carat band, graded I colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1533765117. Listed at 3 retailers as of October 28, 2026, with prices from £15,211 to £17,801, a £2,590 spread on the same certified stone. 77 Diamonds lists it at £17,801. 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.
