  • Star of the South: a Historic 128 Ct Diamond
    STAR OF THE SOUTH: A HISTORIC 128 CT DIAMOND By Christopher P. Smith and George Bosshart The Star of the South is one of the world’s most famous diamonds.

A little information about topics such as formation, sources, mining, or cutting can often help, too. In every pre- sentation, however, it’s essential to identify and reinforce the factors that make diamonds valuable and important – in other words, truly precious – to each customer. After all, purchase decisions involve the head, but the desire to own or give a diamond almost always springs from the heart. That’s the realm of magic and romance. The emotional meanings of diamonds have many origins and they have evolved over thou- sands of years.

  • Crystal Chemistry
    Crystal chemistry About a girl’s best friend - diamonds Diamonds, a crystalline form of the chemical element carbon, are the most romantic of crystals, given as symbols of love and permanence. They were first discovered around 800 BC in riverbeds in India. One of the world’s richest source of diamonds is South Africa, where they are mined from rock called ‘Kimberlite pipe’, named after the town Kimberley. Other countries rich in diamonds are Australia, Botswana, Zaire and the former Soviet Union. Diamonds formed in volcanic magma about 170 miles below the Earth’s surface, solidifying as the magma moved upwards and cooled. This took a long time! Diamond The Cullinan diamond, with a mass of 621.2 g, was the largest diamond ever found, mined in 1895. This was a bit big for one engagement ring, so it was decided to cut the diamond into smaller pieces. The diamond cutter spent months deciding how to go about the task, and apparently fainted with shock after first splitting the stone in two. He recovered, and finally nine large and 96 smaller diamonds were produced. The most famous large diamond, called ‘Cullinan I’ or the ‘Star of Africa’ is in the Royal Sceptre and can be seen on a visit to the Crown Jewels in the Tower of London. The Cullinan 1 Crown © / The Royal Collection © 2004, Her Majesty Queen Elizabeth II. Diamond is the hardest known substance, so can only be cut with a diamond-edged saw! Diamond mass is measured in ‘carats’. One carat is equal to 0.2 g.

Today there is very little that is ‘constant’ and keeping up with continuous change is a ‘must’ to succeed. Our customers are more discerning, knowledgeable and demanding than ever before. They are busy and bore easily, so it is not enough, however successful your business is to continue to do the same things in the same way that we have in the past. Jewellery has long enjoyed a unique status among luxury goods and as an industry it is easy to take this appeal for granted, as if jewellery would sell itself. But in today’s competitive environment, we have to pro-actively drive jewellery sales in the same way all other luxury businesses do. We have to compete with all the other luxuries on offer to today’s consumer. We all have to bring innovative ideas to our consumers on a regular basis – through this we will inspire a passionate desire to buy. This Guide This guide is intended to help jewellery retailers by: • Challenging the unexamined assumptions of jewellery retailing; • Providing detailed case studies; and • Demonstrating the use of effective tools to drive sales. To effectively sell diamond jewellery one must uphold certain standards of excellence.

    HAZARD COMMUNICATIONS (HAZCOM) SYMBOLS A training document written by: Steve Serna The Occupational Safety and Health Administration (OSHA) has determined that workers have a, “right to know” what chemical hazards are present in their particular work areas, or what chemical hazards they might encounter on their work sites. This information is written in 29 CFR 1910.1200 of the US Code. HAZCOM (Hazard Communications) relies on several written documents (MSDS & written programs) and various symbols or pictograms to inform the employee regarding chemical hazards or potential hazards. The law requires that all chemical containers/vessels have labels and adhere to a set standard; here is a quick explanation of some of the various symbols and pictograms… NFPA The National Fire Prevention Association is a private organization that catalogues and works to enact legislation for fire prevention in industrial and home settings. Most US Fire Departments rely on NFPA symbols to warn them of danger present in buildings. The NFPA Fire Diamond symbol is the common identifier along with a rating number (from 0-4) inside of a colored field to indicate a hazard rating.
