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 standard cut grade stated by the retailer rather than the lab and certified by GIA 6501279124. Listed at 23 retailers as of October 29, 2026, with prices from HK$5,171 to HK$12,296, a HK$7,126 spread on the same certified stone. MOH London lists it at HK$12,296. 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.
