About this 1.55ct natural oval diamond

This 1.55ct 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 standard cut grade stated by the retailer rather than the lab and certified by HRD 170002871352. Listed at 3 retailers as of November 4, 2026, with prices from $7,590 to $12,316, a $4,726 spread on the same certified stone. MOH London lists it at $12,316. 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.
