About this 1.59ct natural heart diamond

This 1.59ct 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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 1146798237. Listed at 3 retailers as of November 2, 2026, with prices from HK$58,320 to HK$76,540, a HK$18,220 spread on the same certified stone. 77 Diamonds lists it at HK$76,540. 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.
