About this 0.51ct natural heart diamond

This 0.51ct natural heart sits in the half to three-quarter carat band, graded I colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7518503131. Listed at 7 retailers as of November 2, 2026, with prices from HK$5,547 to HK$9,981, a HK$4,434 spread on the same certified stone. Diamond Exchange Canada lists it at HK$9,981. 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.
