About this 0.59ct natural oval diamond

This 0.59ct 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 6551869120. Listed at 2 retailers as of October 31, 2026, with prices from £366 to £425, a £59 spread on the same certified stone. 77 Diamonds lists it at £425. 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.
