About this 1.63ct natural oval diamond

This 1.63ct natural oval sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1478179775. Listed at 2 retailers as of November 4, 2026, with prices from $7,824 to $11,972, a $4,149 spread on the same certified stone. MOH London lists it at $11,972. 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.
