About this 0.51ct natural heart diamond

This 0.51ct natural heart sits in the half to three-quarter carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1545836843. Listed at 5 retailers as of November 6, 2026, with prices from HK$4,561 to HK$6,659, a HK$2,098 spread on the same certified stone. Steven Stone lists it at HK$6,659. 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.
