About this 3.5ct natural cushion diamond

This 3.5ct natural cushion sits in the three to five carat band, graded H 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 7546929131. Listed at 12 retailers as of November 4, 2026, with prices from HK$304,303 to HK$501,487, a HK$197,184 spread on the same certified stone. MOH London lists it at HK$501,487. 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.
