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 30, 2026, with prices from $50,577 to $94,247, a $43,669 spread on the same certified stone. MOH London lists it at $94,247. 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.
