About this 1.01ct natural radiant diamond

This 1.01ct natural radiant sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6481532217. Listed at 23 retailers as of November 5, 2026, with prices from £1,649 to £4,213, a £2,564 spread on the same certified stone. NZ Jewellers lists it at £4,213. 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.
