About this 1.53ct natural heart diamond

This 1.53ct natural heart sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1553492009. Listed at 3 retailers as of November 1, 2026, with prices from HK$42,902 to HK$57,238, a HK$14,336 spread on the same certified stone. 77 Diamonds lists it at HK$57,238. 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.
