This 0.51ct lab-grown 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 and certified by IGI LG407915168 or 407915168. Listed at 11 retailers as of October 29, 2026, with prices from HK$1,914 to HK$9,546, a HK$7,631 spread on the same certified stone. MOH London lists it at HK$9,546. 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.
