About this 1.28ct natural round diamond

This 1.28ct natural round sits in the one-and-a-quarter to one-and-a-half carat band, graded I colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by GIA 2151635387. Listed at 6 retailers as of October 31, 2026, with prices from HK$36,506 to HK$50,161, a HK$13,655 spread on the same certified stone. Yorxs lists it at HK$50,161. 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.
