About this 3.5ct natural oval diamond

This 3.5ct natural oval sits in the three to five carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2557402558. Listed at 20 retailers as of October 29, 2026, with prices from $40,581 to $76,023, a $35,443 spread on the same certified stone. MOH London lists it at $76,023. 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.
