About this 0.51ct natural oval diamond

This 0.51ct natural oval sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1528479257. Listed at 10 retailers as of October 31, 2026, with prices from HK$3,892 to HK$11,071, a HK$7,179 spread on the same certified stone. MOH London lists it at HK$11,071. 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.
