About this 0.45ct natural heart diamond

This 0.45ct natural heart sits in the sub-half-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1565292224. Listed at 3 retailers as of November 2, 2026, with prices from HK$3,366 to HK$4,206, a HK$840 spread on the same certified stone. 77 Diamonds lists it at HK$4,206. 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.
