About this 0.51ct lab-grown oval diamond

This 0.51ct lab-grown oval sits in the half to three-quarter carat band, graded G 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 6485252119. Listed at 9 retailers as of October 31, 2026, with prices from HK$745 to HK$7,453, a HK$6,708 spread on the same certified stone. Do Amore Diamonds lists it at HK$7,453. 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.
