About this 0.5ct natural round diamond

This 0.5ct natural round sits in the half to three-quarter carat band, graded K colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 2526923018. Listed at 15 retailers as of November 1, 2026, with prices from £348 to £1,406, a £1,058 spread on the same certified stone. NZ Jewellers lists it at £1,406. Flawless clarity in sub-one-carat stones is rarely visible to the naked eye over VS1, so you are paying a meaningful premium for grade rather than appearance.
