About this 0.7ct natural heart diamond

This 0.7ct natural heart sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6555421803. Listed at 4 retailers as of October 30, 2026, with prices from HK$4,175 to HK$5,175, a HK$1,000 spread on the same certified stone. 77 Diamonds lists it at HK$5,175. 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.
