About this 0.51ct natural heart diamond

This 0.51ct natural heart sits in the half to three-quarter carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2526619322. Listed at 4 retailers as of November 4, 2026, with prices from HK$7,869 to HK$13,855, a HK$5,987 spread on the same certified stone. MOH London lists it at HK$13,855. 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.
