About this 1.31ct natural heart diamond

This 1.31ct natural heart sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2155358278. Listed at 3 retailers as of November 6, 2026, with prices from HK$24,845 to HK$45,175, a HK$20,330 spread on the same certified stone. Wholesale Diamonds Direct lists it at HK$45,175. 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.
