About Quality Diamonds

About Quality Diamonds

Quality Diamonds is a family-owned business run by cousins Paul and Dave Sitton.

What we can do for you

Being a well established Diamond retailer, we’re dedicated to bringing you the highest quality Diamonds at the best prices on the internet. Additionally, as a member of the British Jewellers Association, we guarantee you'll find the exquisite experience and personal service you’d expect when buying from a Hatton Garden jeweller.  

The Four P's

You can’t buy a Diamond without hearing about the Four C's. But did you know, when you shop with us you also get the Four P’s at no extra cost?

(We tried to come up with Four Q’s, for Quality Diamonds, but it was just too hard!)


  • From simple elegant bands to intricate Diamond set pieces, our Collection represents the very best of classic and contemporary styles.
  • Both our Diamond experts and our online search facility empower you to identify the highest quality conflict-free Diamonds from around the world.
  • All our 150,000 Diamonds are certified by one of the six leading independent gemological laboratories (GIA, AGS, EGL and EGL USA, IGI and HRD).
