About this 1.5ct natural oval diamond

This 1.5ct natural oval sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5436091439. Listed at 18 retailers as of November 5, 2026, with prices from HK$18,520 to HK$57,621, a HK$39,101 spread on the same certified stone. Adiamor lists it at HK$57,621. 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.
