About this 3.51ct natural oval diamond

This 3.51ct natural oval sits in the three to five carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by HRD 250000297188. Listed at 7 retailers as of October 29, 2026, with prices from $27,113 to $43,775, a $16,662 spread on the same certified stone. MOH London lists it at $43,775. 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.
