Pearl and Stone Guide


The pearl is the birthstone for June and  pearl jewellery is traditionally given to mark the 3rd and 30th wedding anniversary.

Claudia uses cultured freshwater pearls in all her designs. We are sometimes asked if these are ‘real’ pearls. The answer is yes, they are made in the same way a natural pearl is, the difference is that in a cultured pearl, the irritant is introduced by man rather than nature.

Each pearl is a work of art taking years to form; every pearl is unique in colour, lustre, size and shape. The characteristic of each pearl depends on the mollusc and its environment; these individual characteristics should not be mistaken for imperfections or flaws.

Because pearls are formed as a result of irritation, they are believed to hold the key to the ability to overcome pain and troubles. Pearls represent faith, charity, purity and innocence. They are said to enhance concentration and meditation while inspiring wisdom and tranquility.

You can learn more about cultured pearls on our 'Story Of Cultured Pearls' page and you can watch Claudia's short video to learn about her criteria for choosing the right pearl on our 'Video page'.

White and Pink Pearls

The white and pink pearls Claudia uses in her designs are presented in their natural colour.

Peacock and Silver Pearls

The colour of the peacock and silver pearls Claudia uses in her designs is achieved using a heat treatment that creates a chemical reaction in the pearl. This colour is permanent and will not fade.

Green Chalcedony

The bright apple green translucent chalcedony, is the most valued variety of chalcedony. It was a particular favorite of Frederick The Great of Prussia, who loved its bright green colour. It can be seen today decorating many buildings in beautiful Prague, including the Chapel of St Wencelas. Chrysoprase is found today mostly in Australia. Unlike most other green stones, which owe their colour to chromium or vanadium, chrysoprase derives its colour from nickel. Its bright even colour and texture lends itself well to beads, cabochons, and carvings.

Claudia has used green chalcedony in the Brea range, which forms an integral part of the Romancing The Stone collection.

Rose Quartz

Rose quartz is a quartz crystal that owes its pink hue to the presence of several minerals. The colour ranges from very pale to deep fresh pink. Claudia favours the pale pink quartz for her designs.

Believed  to bring love, it represents  kindness, caring and forgiveness. A stone of romance, rose quartz is said to promote love and improve one's self confidence. Rose quartz has long been a favourite with Claudia and collectors of her designs. It features in our summer collections and is a key stone in our Camellia necklace and features in the Kate Quartz necklace and earrings.


Iolite is a semi precious stone and the name comes from the Greek ios, which means violet. It is the gem version of the mineral Cordierite, and also referred to as a water sapphire. It is said to help in recovering balance and is recommended for those suffering from disorientation.


Druzy Quartz


Druzy is a layer of minute quartz crystals that have crystallized on the surface of another gemstone or mineral. The gem is believed to stabilizing the aura and to help in clear, pragmatic and creative thinking.

Claudia has used druzy quartz to dramatic and glamorous effect in our Basilia earrings.


The moonstone is associated with the moon and was the stone of the goddess Diana. Throughout history It has been worn as an amulet to bring good emotions to the wearer, while protecting those of a sensitive nature. Moonstone is also considered a good luck stone.

The moonstones Claudia uses  in the Assana collection are sourced in India and display the subtle grey/beige tones that are typical of moonstone from that region.


The meaning of the name of this stone relates to the Amazon River, as it is a location where there are considerable deposits of the stone. Amazonite is also found in Madagascar, Russia, Canada, Namibia, Mozambique, India, Brazil and the USA.This blue-green crystal is an extremely soothing and calming stone, and varies in colour from milky blue through to darker greeny blue.

Claudia has used amazonite  in our Camellia necklace and it is the feature stone in the Elizabeth necklace, bracelet and Hydra earrings and it is also the central stone in the Sweetpea range.


Pyrite is a disulphide of iron, and the metallic crystal grows in cubes, nodules, masses of tiny crystals, and can even be found as flat discs. It has been used in the jewellery industry for thousands of years,  specimens have been found in ancient civilizations of the Greeks, Romans and the Incas.

Claudia mixes tiny faceted coated pyrite beads with a single pearl in our Lucia designs, which both complement and contrast with each other beautifully and they are the main feature of our  Encanto earrings.


Labradorite  is treasured for its remarkable play of colour, known as labradorescence.  It was first discovered in Labrador, Canada, by Moravian missionaries in 1770 who named it for the area. It became a popular gem in Europe in the eighteenth and nineteenth centuries.

The versatility of labradorite makes it  a popular stone choice for Claudia and it is used to beautiful effect in our Kasia designs Encanto necklace and in the Architect's bracelet.


Turquoise beads date back to 5000 B.C. and  is one of  the oldest stone in man’s history, the talisman of kings, shamans and warriors. The delicate veining or mottled webbing in cream or brown is inherent to the stone and makes each piece individual. 

Historically, Turquoise is credited with the property of securing friendly regard, the traditional saying is that “he, or she, who owns a Turquoise will never want for a friend.” 

Turquoise is  a perennial favourite with Claudia Bradby collectors and it features in the Marina range from the S14 Romancing The Stone collection.


Black Spinel

Black spinel is not well-known among the gem world, yet its outstanding features make it the ideal choice for an opaque black gem. These days, where most gems undergo routine enhancement treatments, black spinel can stand proud as a gem requiring nothing more than cutting and polishing to bring out its inner beauty. 

There is a wealth of mythology surrounding black spinel. It is believed to protect its owner from harm, to reconcile differences, and to console sadness. Some say that black spinel is the stone for people born on Saturday and it is the recommended gift for the 22nd wedding anniversary.

Claudia only uses machine cut black spinel which is coated to give it a sparkle akin to black diamonds. It features in the Encanto bib necklace and earrings




Agate is a fine-grained chalcedony quartz and one of the first gem materials known. Its history goes all the way back to the ancient Egyptians, who
first used it for adornment more than 3,000 years ago. Ancient cultures used it in amulets and talismans. They believed that it provided the wearer with
a bold heart and pleasant dreams. Roman artisans carved seals from it. Nineteenth century Victorians used it to create beautiful cameos.

Claudia has used a white agate charm to complement the turquoise bead and silver starfish on the Marina pendant from the Romancing the Stone S14 collection.


Blue Chalcedony

Chalcedony is a member of the Quartz family with a cryptocrystalline structure. Blue Chalcedony is a demure crystal, subtle and mystic,cool and serene, ethereal yet solid. It has an inviting, soft blue translucence that invokes a calming stillness. 

Claudia has used this beautiful stone in her limited edition Isis collection.



Recommended Care Of Your Pearls

We recommend that your pearls and beads should be re-strung every 12 months to avoid accidental breakage from wear and tear.

You must not wet your pearls (especially in swimming pools, the shower, etc)

Avoid wet perfume near pearls as this will damage them.

Make sure your pearls are put away when you are using any hair sprays as this will damage them.

Always store your pearls in the Claudia Bradby Jewellery pouch they were supplied in when not in use.
