For most of our jewellery the metal used is silver. We add extra shine and durability by having them plated in either Rhodium, 18k Yellow gold, or 18k Rose-gold, but we’ll elaborate on that in the following paragraphs. As you will see, the plating adds a lot of benefits to the finished product.
We also have a small range of brass or other alloys bijoux. When we saw the models we just couldn’t help ourselves, so we advise you not to judge. They caught our eye and stole our hearts, and we believe they will have the same impact on you.
It’s important to know that silver is one of the only 4 precious metals used in jewelry. The other 3 are platinum, gold, and (less spread) palladium. Jewelry made of precious metal is considered to be and referred to as fine jewelry. However, in comparison to gold and platinum, silver is much more affordable. And nowadays it can have the same look as gold because of the special plating techniques. It can be plated in Rhodium, yellow gold, rose gold etc.
Rhodium, for instance, is a silvery-white precious metal, member of the platinum family. White gold is actually an alloy of Gold and Rhodium, and it’s also often plated with a thin rhodium layer to improve its appearance, while sterling silver is often rhodium plated for tarnish resistance. It is the material most often used to plate jewelry because of its highly-reflective finish, hardness, and corrosion resistance. It is also hypoallergenic, and will prevent the jewelry from leaving a greenish tinge on the skin. Thus, Rhodium plated silver is the best type of jewelry because it will not tarnish (it doesn’t fade or become darker), looks almost the same as white gold, and costs a tenth of the price.
In case you decide you aren’t happy with the plating of a piece, it can be done/redone by a qualified jeweler, and can even be removed if desired.
But this is only half the story, because no ring would be complete without a beautiful stone or set of crystals. And we truly have a wide array of them, as you will notice while visiting our site.
From the beginning we just want to assure you that all the stones we have are natural semi-precious gemstones. Please take into account that they are all fragile, and we advise you to carefully read the care instructions.
One of the most used gemstone that you will encounter on our website under many shapes and colors is cubic zirconia. Single crystals of the cubic phase of zirconia are commonly used as diamond simulant in jewellery. Like diamond, cubic zirconia has a cubic crystal structure and a high index of refraction. Visually discerning a good quality cubic zirconia gem from a diamond is difficult, and most jewellers will have a thermal conductivity tester to identify cubic zirconia by its low thermal conductivity (diamond is a very good thermal conductor). This state of zirconia is commonly called cubic zirconia, CZ, or zircon by jewellers, but the last name is not chemically accurate. Zircon is actually the mineral name for naturally occurring zirconium silicate. We will continue to list some of the stones and crystals you can discover in our jewellery.
Lapis lazuli, or lapis for short, is a deep blue semi-precious stone that has been prized since antiquity for its intense colour.
Lapis lazuli was being mined in the Sar-i Sang mines and in other mines in the Badakhshan province in northeast Afghanistan as early as the 7th millennium BC. Lapis beads have been found at neo-lithic burials in Mehrgarh, the Caucasus, and even as far from Afghanistan as Mauritania. It was used for the eyebrows on the funeral mask of King Tutankhamun (1341–1323 BC). At the end of the Middle Ages, lapis lazuli began to be exported to Europe, where it was ground into powder and made into ultramarine, the finest and most expensive of all blue pigments. It was used by the most important artists of the Renaissance and Baroque, including Masaccio, Perugino, Titian and Vermeer, and was often reserved for the clothing of the central figure of the painting, especially the Virgin Mary. Today mines in northeast Afghanistan and Pakistan are still the major source of lapis lazuli. Important amounts are also produced from mines west of Lake Baikal in Russia, and in the Andes mountains in Chile. Smaller quantities are mined in Italy, Mongolia, the United States and Canada.
Agate is a cryptocrystalline variety of silica, chiefly chalcedony, characterised by its fineness of grain and brightness of colour. Although agates may be found in various kinds of rock, they are classically associated with volcanic rocks and can be common in certain metamorphic rocks. The stone was given its name by Theophrastus, a Greek philosopher and naturalist, who discovered the stone along the shore line of the river Achates in present-day Sicily, sometime between the 4th and 3rd centuries BC. Colourful agates and other chalcedonies were obtained over 3,000 years ago from the Achates River, now called Dirillo. Agate was one of the most common materials used in the art of hardstone carving, and has been recovered at a number of ancient sites, indicating its widespread use in the ancient world; for example, archaeological recovery at the Knossos site on Crete illustrates its role in Bronze Age Minoan culture.
Spinel crystallizes in the isometric system, common crystal forms being octahedra, usually twinned. It has an imperfect octahedral cleavage and a conchoidal fracture. Its hardness is 8, its specific gravity is 3.5–4.1 and it is transparent to opaque with a vitreous to dull luster. It may be colorless, but usually it’s found in various shades of red, blue, green, yellow, brown, or black. There is a unique natural white spinel, now lost, that surfaced briefly in what is now Sri Lanka. Some spinels are among the most famous gemstones: Among them are the Black Prince’s Ruby and the “Timur ruby” in the British Crown Jewels, and the “Côte de Bretagne”, formerly from the French Crown jewels. The Samarian Spinel is the largest known spinel in the world, weighing 500 carats (100 g). The transparent red spinels were called spinel-rubies or balas rubies. In the past, before the arrival of modern science, spinels and rubies were equally known as rubies. After the 18th century the word ruby was only used for the red gem variety of the mineral corundum and the word spinel came to be used. “Balas” is derived from Balascia, the ancient name for Badakhshan, a region in central Asia situated in the upper valley of the Kokcha River, one of the principal tributaries of the Oxus River. The Badakshan Province was for centuries the main source for red and pink spinels.
Turquoise is an opaque, blue-to-green mineral that is a hydrous phosphate of copper and aluminium. It is rare and valuable in finer grades and has been prized as a gem and ornamental stone for thousands of years owing to its unique hue. In recent times, turquoise, like most other opaque gems, has been devalued by the introduction of treatments, imitations, and synthetics onto the market. The substance has been known by many names, but the word turquoise, which dates to the 17th century, is derived from the French turques for “Turks”, because the mineral was first brought to Europe from Turkey, from the mines in historical Khorasan Province of Persia. Pliny the Elder referred to the mineral as callais and the Aztecs knew it as chalchihuitl. Even the finest of turquoise is fracturable, reaching a maximum hardness of just under 6, or slightly more than window glass. Turquoise almost never forms single crystals and all of its properties are highly variable. These properties are dependent on grain size. The lustre of turquoise is typically waxy to subvitreous, and transparency is usually opaque, but may be semi-translucent in thin sections. Colour is as variable as the mineral’s other properties, ranging from white to a powder blue to a sky blue, and from a blue-green to a yellowish green.
Amethyst is a violet variety of quartz often used in jewellery. Amethyst is a semiprecious stone and the traditional birthstone for February. The hardness of the mineral is the same as quartz, thus it is suitable for use in jewellery making. Amethyst occurs in primary hues from a light pinkish violet to a deep purple. It may exhibit one or both secondary hues, red and blue. The best varieties of Amethysts can be found in Siberia, Sri Lanka, Brazil and the Far East. The ideal grade is called “Deep Siberian” and has a primary purple hue of around 75–80%, with 15–20% blue and (depending on the light source) red secondary hues. Amethyst can fade in tone if overexposed to light sources and can be artificially darkened with adequate irradiation.
Tanzanite is the blue/violet variety of the mineral zoisite, and it belongs to the epidote group. It was discovered in the Mererani Hills of Manyara Region in Northern Tanzania in 1967, near the city of Arusha and Mount Kilimanjaro. Tanzanite is used as a gemstone, and naturally formed tanzanite is extremely rare, still found only in the Mererani Hills. Tanzanite is noted for its remarkably strong trichroism (which means it shows three colours), appearing alternately sapphire blue, violet and burgundy depending on crystal orientation. Tanzanite can also appear differently when viewed under alternate lighting conditions. It is usually a reddish brown in its rough state, requiring artificial heat treatment to bring out the blue violet of the stone. In 2002, the American Gem Trade Association chose Tanzanite as a December birthstone, the first change to their birthstone list since 1912.
Citrine is a variety of quartz whose color ranges from a pale yellow to brown due to ferric impurities. Natural citrines are rare, and most commercial citrines are heat-treated amethysts or smoky quartzes. However, a heat-treated amethyst will have small lines in the crystal, as opposed to a natural citrine’s cloudy or smokey appearance. It is nearly impossible to tell cut citrine from yellow topaz visually, but they differ in hardness. Brazil is the leading producer of citrine, with much of its production coming from the state of Rio Grande do Sul. The name is derived from Latin citrina which means “yellow” and is also the origin of the word “citron.” Sometimes citrine and amethyst can be found together in the same crystal, which is then referred to as ametrine.
Topaz is a silicate mineral of aluminium and fluorine. Pure topaz is colorless and transparent but is usually tinted by impurities; typical topaz is wine red, yellow, pale grey, reddish-orange, or blue brown. It can also be made white, pale green, blue, gold, pink (rare), reddish-yellow or opaque to transparent/translucent. Orange topaz, also known as precious topaz, is the traditional November birthstone, the symbol of friendship, and the state gemstone of the US state of Utah.
Imperial topaz is yellow, pink (rare, if natural) or pink-orange. Brazilian Imperial Topaz can often have a bright yellow to deep golden brown hue, sometimes even violet. Many brown or pale topazes are treated to make them bright yellow, gold, pink or violet colored. Some imperial topaz stones can fade on exposure to sunlight for an extended period of time. Blue topaz is the state gemstone of the US state of Texas. Naturally occurring blue topaz is quite rare. Typically, colorless, gray or pale yellow and blue material is heat treated and irradiated to produce a more desired darker blue. Mystic topaz is colorless topaz which has been artificially coated giving it the desired rainbow effect. Nicols, the author of one of the first systematic treatises on minerals and gemstones, dedicated two chapters to the topic in 1652. In the Middle Ages, the name topaz was used to refer to any yellow gemstone, but in modern times it denotes only the silicate described above.
Jade is an ornamental rock. The term jade is applied to two different metamorphic rocks that are made up of different silicate minerals: Nephrite and Jadeite. Among the earliest known jade artifacts excavated from prehistoric sites are simple ornaments with bead, button, and tubular shapes. Additionally, jade was used for adze heads, knives, and other weapons, which can be delicately shaped. As metal-working technologies became available, the beauty of jade made it valuable for ornaments and decorative objects. Jadeite measures between 6.0 and 7.0 Mohs hardness, and nephrite between 6.0 and 6.5, so it can be worked with quartz or garnet sand, and polished with bamboo or even ground jade. In the history of the art of the Chinese empire, jade has had a special significance, comparable with that of gold and diamonds in the West. Jade was used for the finest objects and cult figures, and for grave furnishings for high-ranking members of the imperial family. Due to that significance and the rising middle class in China, today the finest jade when found in nuggets of “mutton fat” jade — so-named for its marbled white consistency — can fetch $3,000 an ounce, a tenfold increase from a decade ago.
A pearl is a hard object produced within the soft tissue (specifically the mantle) of a living shelled mollusk. Just like the shell of a clam, a pearl is composed of calcium carbonate in minute crystalline form, which has been deposited in concentric layers. The ideal pearl is perfectly round and smooth, but many other shapes (baroque pearls) occur. The finest quality natural pearls have been highly valued as gemstones and objects of beauty for many centuries. Because of this, pearl has become a metaphor for something rare, fine, admirable and valuable. The most valuable pearls occur spontaneously in the wild, but are extremely rare. These wild pearls are referred to as natural pearls. Cultured or farmed pearls from pearl oysters and freshwater mussels make up the majority of those currently sold. Pearls have been harvested and cultivated primarily for use in jewelry, but in the past were also used to adorn clothing. They have also been crushed and used in cosmetics, medicines and paint formulations. Whether wild or cultured, gem-quality pearls are almost always nacreous and iridescent, like the interior of the shell that produces them. However, almost all species of shelled mollusks are capable of producing pearls of lesser shine or less spherical shape. Although these may also be legitimately referred to as “pearls” by gemological labs and also under U.S. Federal Trade Commission rules, and are formed in the same way, most of them have no value except as curiosities.
These are the most common gemstones you will find in our collection. Please understand that most of them can easily be chipped due to their physical properties, or that they can lose their shine or transparency due to sun exposure. Unfortunately, this is what “natural gemstone” implies, but we consider it’s worth the risk taking into account the beauty that synthetic stones could never provide.
