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 very-good cut grade and certified by IGI 840603035. Listed at 14 retailers as of October 30, 2026, with prices from HK$4,104 to HK$13,950, a HK$9,847 spread on the same certified stone. NZ Jewellers lists it at HK$13,950. 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.
