Materials & Technical Information

Sterling silver

Sterling silver is an alloy of silver. It contains 92.5% of silver and 7.5% of another metal, usually copper.

Sterling silver contains 925 parts out of 1,000 of actual ne silver. You can nd the ‘925’ stamp on Ster-

ling Silver jewellery. Because ne silver (99.9% pure) is generally too soft for producing functional ob-

jects, the silver is usually alloyed with copper to give it strength while preserving the ductility and beauty

of the precious metal. Other metals can replace the copper, usually with the intent to improve various

properties of the basic sterling alloy such as reducing casting porosity, eliminating rescale, and increas-

ing resistance to tarnish.

Stainless Steel (316)

Marine Grade Stainless Steel (316) is a stainless steel often used in marine environments because of

its resistance to rust and corrosion. It is also commonly used surgically for piercings and implants. It is

an anti-allergy and anti-tarnish steel. The AISI number grade is 316 and refers to the chromium content.

The alloy is more resistant to rust than household stainless steels, and hence more expensive.

Ion plating

IP plating is one of the newest and most advanced surface nishing processes now available at

Pastiche. It produces a harder and more durable coating with a higher brightness than that produced

through traditional plating methods. Experiments haveproved that the plating obtained through IP plating

is ve to eight times better than that obtained through conventional methods in terms of wear and

corrosion resistance. Throughout the Jewellery industry IP plating is available in a range of colours,

though most commonly used in black, brown, rose gold and yellow gold.


While Bronze had its origins in militant uses like spearheads and arrows, it didn’t take the ancient

world long to see the potential of bronze as a jewellery material. Today, bronze continues to be an

ideal metal for the maufacture of beautiful jewellery; soft enough to work with easily, but hard enough

to last a lifetime. When polished it has a lustre comparable to rose gold, but is more durable and cost

effective. Our bronze pieces have a special epoxy resin coating that will prevent discolouration.


Zirconium is an extremely hard metal that is scratch and corrosion resistant. It’s natural silvery colour is

similar to titanium and it has the ability to take on a charcoal and even onyx like nish when exposed to

high temperatures. Therefore, your dark or two tone zirconium pieces won’t loose their colour as this is

a structural change to the metal rather than a plating. With these properties Zirconium jewellery will

maintain its ‘brand new’ look for a long period of time and is a tough alternative to titanium.

How to Care for your Jewellery

Our jewellery has been crafted with ne materials and with good care can become a treasured piece for a

long time to come. We encourage you to store your jewellery in a clean, dry, tarnish-resistant box or pouch.

Sterling Silver: Over time it is natural for sterling silver to tarnish. Salty air, sunlight, water, humidity and

various chemicals can rapidly speed up this process. To prevent tarnishing, silver should be kept absolutely

dry. Avoid contact with cleaning agents and chemicals. To clean silver, use a Pastiche cleaning cloth to gen-

tly rub over silver surfaces. From time to time sterling silver may require cleaning with products such as Silvo,

Brasso or a small amount of bi-carbonate of soda. Particular care should be taken when cleaning plated

jewellery. Harsh cleaning of jewellery can wear away plated coating.

Stainless Steel: While stainless steel does not oxidize, rust or tarnish it is bene cial to occasionally

clean with a soft cloth and warm water to remove any grime build up. After cleaning, jewellery must be dried

thoroughly with a dry cloth. Avoid contact with cleaning agents and chemicals.

Bronze: Our bronze products have a special epoxy resin coating which will last at least two years. This

means that your items will not discolour and any build up of dust or dirt can be wiped away with a dry, soft

cloth and if needed, warm water. Avoid silver cleaning cloths and other abbrasive silver cleaning products as

these can wear away the protective coating.

Zirconium: Zirconium is highly scratch, corrosion ad tarnish resistant. In fact the black surface has what

can be classed as healing propeties and light scracthes can simply be polished away with a cleaning cloth.

Always be careful with your jewellery when working with tools or in the garden as all metals will scratch

against tough surfaces like stone.

Stones & Swarovski: Excessive water, light and chemicals can alter the colour and appearance of

stones. When not in use, keep stones in a dark dry place. To clean stones, wipe over with soft, slightly moist

cloth (avoid too much moisture). After cleaning, dry thoroughly with a dry cloth.

Enamel: Avoid contact with hard surfaces as enamel can chip or crack if reasonable force is applied.

Enamel is affected by uv light, which can cause discolouration, so when not in use store in a dark, dry

place. To clean enamel, wipe over with soft, slightly moist cloth (avoid too much moisture). After cleaning,

dry thoroughly with a dry cloth.

Murano Glass: Your Murano glass piece is a handmade product. Handle with particular care as con-

tact with hard surfaces can cause chipping and cracking. To clean Murano glass, wipe over with soft, slightly

moist cloth (avoid too much moisture). After cleaning, jewellery must be dried thoroughly with a dry cloth.

Leather: Avoid exposing leather to moisture. Do not wear in water. Leather may change colour due to ex-

posure to the sun and oils in the skin. To keep the leather soft and extend its life, leather conditioner should

be applied.

Rubber/Neoprene: Rubber is a hard wearing material and can be cleaned easily with a damp cloth.

Heat and excessive moisture can cause rubber to become hard.

Wear & Tear

Like anything we use, our jewellery is subjected to wear and tear.

The best advice for keeping any jewellery in top condition is this: Recommend to your customers that

their jewellery should be the last thing that they put on before leaving the house, and the rst thing that

they take off at the end of the day.

Simple things, such as spraying on perfume, can affect some nishes.

Glass pieces are just as liable to damage from impact as any other glass product. If it is dropped, it may

sustain a breakage.

Plated items should be worn as dress pieces and will show wear in a similar way to the plating on a

dress watch. For example: if worn in abrasive situations such as in the garden, against other metal

jewellery, or constant rubbing against a mouse pad, it will show wear quickly. If worn occasionally and

with care, the plating will last for a long time.

Sterling silver is a relatively soft metal and should be treated gently to maintain top condition. Avoid

bending earring posts, applying excess pressure, or straining the delicate hinges on a locket. Be re-

spectful of the properties of the metal.

At Pastiche, we stand behind our product. If a genuine fault occurs we will do our very best to rectify the

problem by either replacing or crediting the item.
