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 $8,095 to $12,388, a $4,293 spread on the same certified stone. MOH London lists it at $12,388. 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.
