About this 5.1ct natural oval diamond

This 5.1ct natural oval sits in the over five carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2526979797. Listed at 21 retailers as of October 28, 2026, with prices from $96,093 to $174,140, a $78,047 spread on the same certified stone. MOH London lists it at $174,140. 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.
