About this 0.45ct natural oval diamond

This 0.45ct natural oval sits in the sub-half-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6552533786. Listed at 10 retailers as of November 6, 2026, with prices from £348 to £535, a £187 spread on the same certified stone. The Diamond Guys lists it at £535. 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.
