About this 0.97ct natural round diamond

This 0.97ct natural round sits in the just-under-one-carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI 815617975. Listed at 8 retailers as of November 3, 2026, with prices from £1,682 to £4,141, a £2,459 spread on the same certified stone. NZ Jewellers lists it at £4,141. 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.
