The metals which we utilize at Aristocrazy for the manufacture of our jewellery are solely and exclusively noble metals. Gold symbolizes purity and majesty. It is the king of metals.

When we refer to 24 carats in jewellery terms we mean 100% pure gold. It is rarely used in the manufacture of jewellery because of its malleability and hence easily deformed. For that reason, the pure 24 karat gold is alloyed with other metals such as copper, silver and palladium to give it greater resistance and hardness. That is the reason why the most commonly use karat grade of gold in jewellery is 18 karats, otherwise known as 75% gold, which means that 25% of the gold has been replaced by other metals (copper, silver…)


No other precious stone can compare to diamond. It is only found in the remotest regions of the earth and its very formation is a miracle in itself. One needs almost a ton of rock to obtain a half carat of crude diamond, a fact which results in diamond being one of the most exceptional and desirable precious stones. Because of its extreme purity and rarity, diamond has become the perfect symbol of eternal love. The name ‘diamond’ comes from the Greek “adamas” meaning indomitable, a reference to its extreme hardness.

Ever since the discovery of diamonds, people have felt proud to own these miracles of nature. Aristocrazy is one of the jewelers with an acknowledged prestige in the purchase of diamonds since 1943

The diamonds in our Collection have been strictly selected one-by-one by our expert gemologists to satisfy the quality standards of Aristocrazy.

Every diamond is unique, nevertheless all diamonds share certain characteristics which allow us to compare and evaluate them. These characteristics are termed the 4C.

The GIA (Gemological Institute of America) developed the 4C (Based on the initials of the four selection criteria: Cut, Color, Carat, Clarity) and the International System of Classification of Diamonds (International Diamond Grading System™) which is the standard adopted by jewellery professionals all over the world.


Just as with Rubies, Sapphire-whose name comes from the Hebrew sappir, which means “The most beautiful thing”- is a variety of the mineral corundum (Oxide of aluminum) and also has a hardness of 9. The most common color for sapphires is an intense blue, but one can also find Sapphires which are rose colored, yellow, green, purple, orange [We call these “fancy”] and even colorless Sapphires. The elements which impart the blue color to Sapphires are iron and titanium. The word Sapphire, when used without specifying the color, always refers to blue Sapphires, and just as with Rubies, normally Sapphires are heat treated to improve the intensity of their color.

We can find Sapphire mines in Southeast Asia (Thailand, Myanmar and Sri Lanka), in Australia, Brazil and many of them are also found in Africa, in countries such as Tanzania, Kenya and Nigeria.

Sapphire has been considered a talisman by many cultures which brings peace to its owner.


Topaz is is a precious stone of mineral origin and has a hardness of 8 in the Mohs scale of mineral hardness. It is one of the most important precious stones. Its names comes from the Red Sea island of Topazios, known today as the island of Zabargad. The commonest elements giving rise to the color of Topaz are iron and chromium

Its color is normally a brownish yellow. Nevertheless, one often finds Topaz which is blue (There are three variants of that blue: Sky Blue, Swiss Blue and London Blue), violet, red, ocre and even colorless. Its price usually varies with the color, with the clearer ones being less expensive and the darker ones being more expensive

Some of the most important deposits of Topaz are found in the Czech Republic, Brazil, Norway, Sweden, Japan, Mexico, Sri Lanka, Myanmar, Pakistan and the USA.


We only use Sterling silver (Known as Plata de Ley in Spain) at Aristocrazy. Silver is a much softer metal than gold and so requires greater care. Silver can be left as is without any surface finishing, with its original color, but it is subject to oxidation and has be cleans frequently. Various finishes may also be applied to silver: Sterling silver coated in rhodium, gold plated silver, oxidized silver, blackened silver, etc…

Many of our Sterling silver pieces of jewellery are plated with 18 karat gold, and this is achieved by a 3 micron thick plating of gold. This coating which we use on the pieces of jewellery at Aristocrazy is one of the strongest available in the marketplace. The final color depends on the gold alloy employed, either yellow gold or rose gold.

Rhodium coated Sterling silver is solver plated with rhodium, which is the same treatment applied to the pieces of jewellery in White gold. The rhodium coating apportions a shine and luminosity to the pieces of jewellery for a higher quality finish. At Aristocrazy we always rhodium plate our pieces of jewellery, except for a few pieces which are oxidized to achieve a specific finish


Just like Sapphire, ruby is a variety of a mineral called Corundum. Corundum is an oxide of aluminum. If no other element is present in the process of creation, then the stone is a colorless Sapphire. Then the red color appears when chromium is present and the stone is transformed into a Ruby. Ruby is a vivid red color, and the value of rubies depends on the color, not on the weight. The intensity of the color of this precious stone depends on the quantity of chromium present.

Because of its rarity, Rubies are the most valuable precious stones after diamonds and rubies also almost as hard (Index of harness 9) as diamonds (Index of hardness 10). Rubies are rare and valuable because of conditions necessary for their formation (Extreme conditions of pressure and temperature and low amounts of silicon in the environment). Normally, Rubies are heat treated to improve their color and this treatment is accepted by the industry and the Gemological Institutes because it is stable and permanent.

Rubies symbolize courage and victory, love and passion.

Black Spinel

Spinel is a precious stone of mineral origin and has a hardness of 8 in the Mohs scale of mineral hardness. Although we only use Black Spinel at Aristocrazy, Spinel is a gem which occurs in a huge range of colors. Spinels are high quality stones, very rare and so are highly valued.


The name derives from “quartz” in German, and its name in antiquity is the Greek word “krystallos” which is also the origin of the word crystal. Most quartz has a hardness of 7 in the Mohs scale of mineral hardness. Quartz is a mineral composed mainly of silicon, but normally these stones have traces of other elements and minerals.

The quartz which we tend to use most in Aristocrazy are Amethyst: This is the most valuable Quartz, and is violet colored and is a pretty clear stone, with few inclusions; Citrine: This is a yellow which is derived from trace amounts of iron and may event come in a redish orange tone; Green Quartz: also known as Green Amethyst; Quartz Fume: This quartz is a crystalline variety and it has a smoky brown color; Black Onyx: This is a cryptocrystalline variety of Quartz and as the name refers, it is black and is of volcanic origin; and Aventurine: This is also a crystalline variety of Quartz with an intense green color and is characterized by the presence of certain inclusions which impart its color and provoke very special bright reflections known as “Aventurescence”. These are some of the numerous varieties of quartz known in gemology.
