About this 3.03ct natural cushion diamond

This 3.03ct 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 1558754513. Listed at 9 retailers as of November 4, 2026, with prices from HK$271,589 to HK$340,569, a HK$68,980 spread on the same certified stone. 77 Diamonds lists it at HK$340,569. 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.
