About this 1.4ct natural oval diamond

This 1.4ct 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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 6515820915. Listed at 18 retailers as of November 5, 2026, with prices from HK$16,952 to HK$47,463, a HK$30,511 spread on the same certified stone. NZ Jewellers lists it at HK$47,463. 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.
