Holloway Diamonds’ focus is on diamond look and sparkle. I am well known worldwide for helping to improve the cut quality and beauty of diamonds, together with the world’s leading research scientists in the field.

I have publicly asked the lab directors of the world’s major labs: “Would you buy a loved one a diamond based only on its grading certificate?” None would. Not even a top colour (D) Flawless diamond lab grading report or certificate tells them if it is a nice sparkly diamond!

When I opened Holloway Diamonds in 1976 (called Precious Metals until 2006), I was a geologist with little diamond and jewellery experience. At the time, I couldn’t understand why most diamonds were poorly cut and lifeless and often cost more than sparkling beauties. The reason I discovered is that grading cut and sparkle is very hard. Most diamonds are ‘Cut for Carats’ not for beauty; Cut is the Cinderella of the 4 C’s.

We hope you will come in, see the difference in our diamonds and buy. If not then please let me help you avoid some pitfalls, and buy a beautiful diamond.
