About this 0.3ct natural cushion diamond

This 0.3ct natural cushion sits in the sub-half-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2518570829. Listed at 9 retailers as of November 4, 2026, with prices from HK$1,654 to HK$5,464, a HK$3,811 spread on the same certified stone. MOH London lists it at HK$5,464. 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.
