People view Valentine's Day through a variety of different lenses. Some people enjoy grand gestures, big dinners, skyscapes with perfect Instagram-able photo opportunities.  This is great, it helps the world turn, supporting the economy & British business.  But it’s not the only way.

Other people do nothing, preferring to dismiss the whole concept as ‘Americanised’ & commercialised, ignoring or mocking those who mark the day in some way.

I think there’s a middle ground.

In short, silver reacts with sulphur oxides present in the air (e.g. hydrogen sulphide) and a black substance is created called silver sulphide.

In order for silver to be strong enough to work with and to have longevity as a piece of jewellery, copper is added in its manufacturing process.

Sterling silver has a purity of 92.5% silver (hence the 925 stamp in the hallmark).  This means that 7.5% of the alloy is copper and other metals like zinc.
