This 0.9ct natural round sits in the just-under-one-carat band, graded M colour (faint-tinted) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by GIA 5386284020. Listed at 6 retailers as of October 31, 2026, with prices from £843 to £1,290, a £447 spread on the same certified stone. Cape Diamonds lists it at £1,290.
