About this 0.65ct natural heart diamond

This 0.65ct natural heart sits in the half to three-quarter 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 2536242964. Listed at 5 retailers as of October 31, 2026, with prices from HK$3,567 to HK$4,708, a HK$1,140 spread on the same certified stone. Blue Nile lists it at HK$4,708. 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.
