About this 0.4ct natural radiant diamond

This 0.4ct natural radiant sits in the sub-half-carat band, graded H 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 7558936486. Listed at 5 retailers as of November 5, 2026, with prices from £371 to £1,260, a £890 spread on the same certified stone. NZ Jewellers lists it at £1,260. 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.
