About this 0.38ct natural marquise diamond

This 0.38ct natural marquise sits in the sub-half-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1545859356. Listed at 3 retailers as of November 1, 2026, with prices from £189 to £246, a £57 spread on the same certified stone. 77 Diamonds lists it at £246. 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.
