About this 1.51ct natural heart diamond

This 1.51ct natural heart sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6482518694. Listed at 14 retailers as of November 4, 2026, with prices from HK$34,093 to HK$68,540, a HK$34,447 spread on the same certified stone. MOH London lists it at HK$68,540. 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.
