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 standard cut grade stated by the retailer rather than the lab and certified by GIA 1568293985. Listed at 4 retailers as of November 4, 2026, with prices from £295 to £378, a £83 spread on the same certified stone. 77 Diamonds lists it at £378. 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.
