Pearl and Stone Guide

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.

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

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.

It is increasingly hard to find good quality dyed pearls. The demand for white pearls is such that the pearls selected for dyeing are predominantly of a lower grade. We only use coloured pearls that have a high quality lustre, shape and weight, so our coloured pearls are in limited supply.

 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 necklace and earrings.

 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.

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 are sourced in India and display the subtle grey/beige tones that are typical of moonstone from that region. Our Signature moonstone  necklace and earrings feature grey moonstone.


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.

Amethyst is the birthstone for February. Purple amethysts are beautiful stones which are believed to have the power to heal; they have been highly regarded through the ages and are one of the most sought after healing crystals.

Our Winter Camellia necklace uses amethyst as an accent stone.


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. 


Agate is a variety of chalcedony, made up from layers of quartz and is the mystical birthstone for September. It is also the birth stone for the zodiac sign of Gemini and  the accepted gemstone for the 12th and 14th wedding anniversaries. It is believed to prevent insomnia and insure pleasant dreams, to enhance personal courage and protect one against danger. Agate provides a calming influence, improves perception, concentration and helps to develop and increase one's analytical talents. 

Soft grey agate is the feature  stone in our  Hebe bracelet and earrings.


Apatite is a mineral, named by the German geologist Abraham Gottlob Werner in 1786. It is said to stimulate thoughts and ideas and is often used in conjunction with meditation to increase intellect, imagination and awareness. 

Claudia has used beautiful blue/green faceted apatite in the Viridian range of jewellery.

Black Spinel

Black spinel is part of a group of minerals and is one of the rarest spinels. Spinel is associated with love and and is also thought to encourage passion and increase the duration of one's life. Black Spinel in particular is said to be a protective stone that assists in re-establishing relationships and resolving issues, it is also believed to ease sadness.

Our Santorini necklace and bracelet feature sparkling black spinel with a feature grey pearl.



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.
