About this 3.51ct natural oval diamond

This 3.51ct 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 6214881150. Listed at 14 retailers as of October 31, 2026, with prices from $78,633 to $123,119, a $44,487 spread on the same certified stone. MOH London lists it at $123,119. 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.
