This 1.51ct natural round sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by GIA 6541094309. Listed at 20 retailers as of October 30, 2026, with prices from HK$22,997 to HK$54,363, a HK$31,366 spread on the same certified stone. NZ Jewellers lists it at HK$54,363. 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.
