About this 0.62ct natural oval diamond

This 0.62ct natural oval sits in the half to three-quarter carat band, graded H 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 6561154600. Listed at 5 retailers as of October 31, 2026, with prices from £493 to £621, a £128 spread on the same certified stone. Blue Nile lists it at £621. 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.
