About this 0.37ct natural oval diamond

This 0.37ct natural oval sits in the sub-half-carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5566560761. Listed at 2 retailers as of November 1, 2026, with prices from £307 to £355, a £48 spread on the same certified stone. 77 Diamonds lists it at £355. 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.
