About this 0.4ct natural heart diamond

This 0.4ct 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 6565240308. Listed at 3 retailers as of October 31, 2026, with prices from HK$2,903 to HK$3,910, a HK$1,007 spread on the same certified stone. 77 Diamonds lists it at HK$3,910. 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.
