Some jewellers use recycled gold that they recast without refining them. The product obtained is less expensive, of lesser quality and more fragile. Honest jewellers do not use this method.

When you wish to purchase a jewel, don’t let deceptive bargains fool you. When it comes to jewels, people fall into the trap by only looking at bargains of 50% to 80%. Take into account the ”net” price, which is the price that you will have to pay.
Colour of gold
For a number of years, jewels are made with two and even sometimes three colours of gold. As a matter of fact, gold, should it be yellow, white or pink, can create magnificent jewels. The colour of gold is modified by using different metals in the alloy to reduce its fineness.
For example: yellow gold 10/24 of pure gold and 14/24 allow of silver and copper. White gold is an alloy made of nickel.
Methods of production
There are several methods of production in jewelry making. Each one has its particularities. A jewel can be made of solid pieces that can be laminated, binded, carved, filed, etc. Another very common method is casting, which is a very popular and solid way of creating jewels.
The striking system is also more and more used. It consists on striking, with a template, on a very thin gold plate to forge the jewel by minimizing the quantity of metal used. This method lowers considerably the price of the jewel, but also its resistance..
