About this 1.51ct natural asscher diamond

This 1.51ct natural asscher sits in the one-and-a-half to two carat band, graded I 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 1428953358. Listed at 11 retailers as of November 6, 2026, with prices from HK$44,054 to HK$61,222, a HK$17,168 spread on the same certified stone. 77 Diamonds lists it at HK$61,222. 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.
