About this 0.91ct natural oval diamond

This 0.91ct natural oval sits in the just-under-one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 790617820. Listed at 13 retailers as of November 1, 2026, with prices from £864 to £1,802, a £938 spread on the same certified stone. Moon Ocean lists it at £1,802. 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.
