National Jewel Day at DMR

By: Amy Brennan-Stephenson

National Jewel Day at DMR

With a calendar full of weird and wonderful holidays, this weekend we celebrate a particularly relevant one… National Jewel Day!

National Jewel Day (13th March) gives us all the opportunity to come together to celebrate the fabulous precious gemstones and jewels that we, at DMR, are privileged to work with each and every day. Throughout our story, which spans over 50 years, our helpful experts have encountered some of the most amazing gemstones on the planet, but some remain especially popular with our friends. Allow us to introduce some of our favourites…


Surely the most famous and certainly the most precious of gemstones, diamonds have been revered the world over for thousands of years. They have played a central role in coronations and ceremonies dating back centuries. In fact, stones cut from the largest diamond ever found – the Cullinan Diamond – are still within the British Crown Jewels which can be viewed at the Tower of London.

Formed deep within the Earth (around 100 miles below the surface), diamonds are created as carbon deposits are subjected to high pressure and temperatures. Noted for their natural strength, diamonds are the hardest natural substance on Earth – did you know the only thing that can scratch a diamond is another?

Cullinan Diamond

The word diamond is derived from the Greek word ‘Adamas’ meaning invincible or indestructible and at 10 on the Mohs scale of hardness, it is clear to see where it got this name.

As diamond experts, DMR’s Sales Ambassadors remain on hand to introduce you to our exclusive collections, including our diamond engagement rings. David Robinson boasts two De Beers Diamond Design Awards, so we know a thing or two about this precious gemstone.

A gemstone noted for its depth of colour, the amethyst is a member of the quartz family of minerals and one of the most notable. The use of amethyst in jewellery can actually be traced back to the Neolithic period (approx. 4000 BC) and archaeologists have found samples of gold rings containing the gem at burial sites from around 2400 BC!

The amethyst is known for its deep purple colour and the intensity of its colour determines the value of the gemstone. Did you know, the most prized amethyst is a Siberian deep purple, which displays red and blue flares.

In comparison to the harder diamond, amethysts are relatively softer than other gemstones. This allows the gem cutter the freedom to be creative in their design work, including cutting cabochons, a domed variation of gemstone cutting.

Keeping with the regal theme, one of the most precious sets of amethyst jewellery in the world is owned by the Swedish royal family. It was initially owned by Napoleon’s first wife, Empress Joséphine before eventually finding its way to its current owner, Queen Silvia of Sweden.

Did you know, the blue vs red division exists within the gemstone world as well as the sporting one? The next of our favourite gems is the sapphire, a member of the corundum family of gemstones. Another member of that family, the ruby, bears a similar chemical structure but is presented in a deep red colour.

In fact, sapphires come in lots of colours, including pink, green, purple, peach, orange, yellow, and more! The gemstone is part of our Compass collection, which you can see here.


When most people think of the sapphire, they picture the 12-carat blue sapphire that was set in Princess Diana’s engagement ring and now worn by the Duchess of Cambridge, but the gemstone has a rich history, popular in the Middle Ages and then cherished by the Greeks and Persians.

Second to diamond in terms of their hardness, the sapphire and other members of the corundum family are graded as nine on the Moh’s scale of hardness, making them a great alternative to diamonds for engagement rings, a piece of jewellery that requires durability for regular wear.
