About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1242075689. Listed at 16 retailers as of October 27, 2026, with prices from £2,954 to £5,261, a £2,307 spread on the same certified stone. Wholesale Diamonds Direct lists it at £5,261. 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.
