This 1.3ct natural round sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by GIA 6431543544. Listed at 18 retailers as of October 31, 2026, with prices from HK$20,197 to HK$60,255, a HK$40,058 spread on the same certified stone. Diamond Quarter lists it at HK$60,255. 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.
