About this 0.4ct natural oval diamond

This 0.4ct natural oval sits in the sub-half-carat band, graded G 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 2556646965. Listed at 11 retailers as of October 29, 2026, with prices from HK$3,515 to HK$8,200, a HK$4,686 spread on the same certified stone. MOH London lists it at HK$8,200. 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.
