This 1.3ct 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 and certified by IGI 737520134. Listed at 7 retailers as of November 2, 2026, with prices from HK$10,941 to HK$27,376, a HK$16,435 spread on the same certified stone. NZ Jewellers lists it at HK$27,376. 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.
