About this 1.37ct natural oval diamond

This 1.37ct natural oval sits in the one-and-a-quarter to one-and-a-half 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 GIA 2225478637. Listed at 5 retailers as of November 4, 2026, with prices from HK$25,291 to HK$55,590, a HK$30,299 spread on the same certified stone. MOH London lists it at HK$55,590. 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.
