About this 0.45ct natural oval diamond

This 0.45ct natural oval sits in the sub-half-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6552815823. Listed at 3 retailers as of November 6, 2026, with prices from £295 to £364, a £68 spread on the same certified stone. 77 Diamonds lists it at £364. 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.
