About this 1ct natural oval diamond

This 1ct natural oval sits in the classic one-carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6445908018. Listed at 21 retailers as of November 3, 2026, with prices from £1,716 to £4,550, a £2,835 spread on the same certified stone. Adiamor lists it at £4,550. 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.
