Gold and Silver
Today we want to talk about the materials we use to produce our pieces. The different types of gold and silver, baths, qualities and durability, the available options on the market, price spectrum and everything that fits in this.
There is, however, a direct correlation between the quality of the raw material used, the price and the durability of the piece.
With regard to the structure and composition of the piece, there are those who use mostly materials such as brass, copper, nickel or metal alloys, which are malleable and quite inexpensive, but of very reduced durability, almost disposable. Some of these materials, such as nickel, are even toxic or, to say the least, highly allergenic to the human skin, causing irritation and allergies to those who wear them. It is the option of large international accessible clothing chains when it comes to the production of accessories. The need to keep production costs and sales prices as low as possible makes them opt for these materials, thus producing dangerous accessories for those who make them, who use them and for the environment itself.
That is definitely not TALLISMA’s choice. Our choice, like the ones taken by renowned jewelry stores, lies in the so-called noble and hypoallergenic materials – in this case, gold and silver. These are distinguished from the previous ones by the resistance to corrosion and oxidation, by the safety for human skin and by the price, being, for all this, much more expensive.
All TALLISMA designs are made of 925 sterling silver. What differentiates colors, tones and luster are the baths we give to each one. We explain the option for this type of silver and the characteristics of each bath. Come with us to the workshop.
Silver is a chemical element that throughout history has served the most diverse purposes, from ornamental objects to monetary systems. Because it has such a distinctive tone, it has always been used in the production of personal adornments and jewelry.
The regulation of the composition of silver in Portugal dates from the 15th century and the king Afonso V, who stipulated the composition of silver at at least 80% pure silver and the remaining 20% other metals, such as copper and brass, in order to stabilize its value and standardize its quality.
Nowadays there are several ratios of silver composition, ranging from the minimum 800 grade, corresponding to 80%, to 1000, or 100%, pure grade. The ratios that fit in this interval defined by this old legislation are the best to work fine jewelry.
This vast majority of pure silver allows to guarantee the quality, safety and durability of the silver and allows the other materials used, such as copper or brass, to serve only as mean to get shape and body, since pure silver does not allow work of jewelry due to its excessive malleability. Thus, silver 950 and silver 925 are the most indicated and most commonly used for jewelry work.
950 silver, composed of 95% pure silver and 5% other materials, has a lower percentage of other materials and is slightly more resistant but, as a result, is too soft to be worked on in our models and in most detailed pieces of jewelry.
925 sterling silver, composed of 92.5% pure silver and 7.5% of other materials, as it presents a more balanced relationship between pure silver and other materials that allows greater durability and malleability, is the type of silver most chosen to work in quality jewelry worldwide. The term Sterling Silver, which we see on so many international jewelry reference sites, refers precisely to 925 sterling silver.
This was our choice to compose and model our designs and to fulfill our vision of offering quality and lasting pieces of jewelry.
TALLISMA pieces have, for now, two different tones: silver and gold. As we have just mentioned, all of our products are made entirely of 925 sterling silver. But that ensures only the robustness and quality that we want, but not the brilliant and polished colors of gold and silver that characterize our rings, necklaces and bracelets. How do we do it? Through the baths we give to our pieces: the rhodium one for the silver pieces and the gold one for the golden pieces. We’ll tell you more about each one now.
Rhodium is a chemical element with high ductility, belonging to the platinum group, and silver in color. It is also an excellent light reflector and is highly resistant to corrosion, being the perfect element to plate the pieces to which we intend to give the silver color. All TALLISMA’s designs that have a silver color are rhodium plated both to make them brighter and to last longer, in an added protection to the quality of the silver we use.
No jewelry store is complete without the most desired precious material in the world. Gold, due to its natural magnetism and beauty, is the most valuable of precious metals.
Gold, just like silver, is too soft to compose pieces of jewelry. In this case, however, the solution was not to melt pure gold with a small percentage of other materials, but to bathe the 925 sterling silver that makes up our pieces with gold. This is mainly due to two factors: the greater hardness of silver versus gold, providing this more detailed work like the ones we present in our collection; and the price of gold, which would take the product to prices that we consider unsuitable for the idea we have for TALLISMA.
Thus, all the golden pieces we sell are pieces composed of 925 sterling silver gold plated. This material is resistant to corrosion by other chemicals and has a purity assessment system similar to that of silver, which is embodied in a measure called carat. The higher the carat of gold, the greater its presence in the composition, where it mixes with the metals that embody it. The scale ranges from 1 to 24 carats, the first corresponding to 4.6% gold compared to the remaining 75.4% of other metals and the second corresponding to 99.99% gold, that is, practically pure gold.
All of our gold baths are made with 24-carat gold, which, being the largest amount of gold in its composition, is the most resistant to corrosion, the most malleable and the one that best applies to the details and embossing to which it will give color.
All the options that we took choosing this materials and that we just told you about here were adopted in order to offer our customers quality pieces that last. And that is the logic that justifies the prices we present, which we consider to be mid-range in the international market.
Our main idea is to offer meaningful and superior quality jewelry pieces, in order to provide a quality and Portuguese alternative to the bipolar market of practically disposable pieces of the big chains, which go up to €10, and of the big luxury brands that offer innocuous pieces and, although higher quality offer, extremely expensive for most people, from €100 upwards.
With a modern and attractive design and a scope of prices that goes from 20 to 90 euros, and presenting an average of 40 euros per piece, we want to be such alternative that represents a Portuguese quality offer to the world.
