About this 0.3ct natural cushion diamond

This 0.3ct natural cushion sits in the sub-half-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1525418159. Listed at 11 retailers as of November 1, 2026, with prices from HK$1,447 to HK$4,803, a HK$3,356 spread on the same certified stone. MOH London lists it at HK$4,803. 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.
