About this 0.51ct natural heart diamond

This 0.51ct natural heart sits in the half to three-quarter carat band, graded J colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 815656492. Listed at 14 retailers as of October 30, 2026, with prices from HK$4,158 to HK$13,079, a HK$8,921 spread on the same certified stone. NZ Jewellers lists it at HK$13,079. 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.
