About this 1.51ct natural heart diamond

This 1.51ct natural heart sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6392388542. Listed at 10 retailers as of November 1, 2026, with prices from HK$89,202 to HK$119,025, a HK$29,823 spread on the same certified stone. Jared lists it at HK$119,025. 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.
