About this 0.4ct natural marquise diamond

This 0.4ct natural marquise sits in the sub-half-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2504663620. Listed at 18 retailers as of October 29, 2026, with prices from HK$2,613 to HK$8,390, a HK$5,777 spread on the same certified stone. MOH London lists it at HK$8,390. 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.
