About this 3.51ct natural oval diamond

This 3.51ct natural oval sits in the three to five carat band, graded J 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 6402339257. Listed at 23 retailers as of October 29, 2026, with prices from $45,532 to $80,957, a $35,425 spread on the same certified stone. MOH London lists it at $80,957. 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.
