About this 0.8ct natural heart diamond

This 0.8ct natural heart sits in the just-under-one-carat band, graded I 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 7531941669. Listed at 5 retailers as of October 31, 2026, with prices from HK$8,819 to HK$15,491, a HK$6,672 spread on the same certified stone. Cape Diamonds lists it at HK$15,491. 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.
