Cutting and Shaping Methods
Paraiba tourmaline is a delicate stone to cut due to its crystalline structure and rarity. Lapidaries must maximize brilliance while minimizing material waste, which is why large stones are extremely rare. The most common cuts include oval, pear, cushion shapes and sometimes cabochons for opaque or slightly included specimens. Paraibas are generally set in white gold or platinum to enhance their electric brilliance. Paraiba tourmaline is much more than a precious stone: it is a true work of natural art. Its brilliant color and rarity make it essential for collectors and lovers of exceptional jewelry. At the intersection of science, art and nature, it continues to fascinate and inspire the world of jewelry.
Sustainability and Ethical Sourcing
The original deposits of Paraiba tourmaline in Brazil are virtually exhausted, which has prompted researchers to explore other regions such as Mozambique and Nigeria, where similar gemstones have been discovered. However, Brazilian stones remain the most sought-after for their exceptional quality and intense color. Due to its rarity, Paraiba mining poses ethical and environmental challenges. Modern initiatives attempt to ensure responsible extraction, but it is essential to ensure that stones come from certified sources respecting ethical standards.
Origin and history
The discovery of Paraiba tourmaline is relatively recent, dating to 1987, by Brazilian researcher Heitor Dimas Barbosa, who had an ambitious vision of finding an extraordinary gemstone. After years of prospecting, he finally uncovered this unique stone in a mine in the state of Paraíba, thus giving the gemstone its name. Due to its rarity, Paraiba quickly achieved a mythical status, becoming a stone of choice in fine jewelry. Paraiba tourmaline is today associated with joy, energy and vitality, its vibrant hues reminiscent of tropical waters. It is also perceived as a stone that stimulates creativity and promotes self-expression.
Uses
Paraiba tourmaline is a flagship stone in fine jewelry, often used in custom creations. It is found in spectacular rings, delicate pendants and earrings that showcase its vibrant hues. Contemporary designs frequently pair it with colorless diamonds or other precious stones to accentuate its unique brilliance. Paraiba tourmaline is much more than a precious stone: it is a true work of natural art. Its brilliant color and rarity make it essential for collectors and lovers of exceptional jewelry. At the intersection of science, art and nature, it continues to fascinate and inspire the world of jewelry.
Care and storage
Paraiba tourmaline, while relatively hard, requires precautions to preserve its brilliance. Avoid any contact with chemicals, as well as physical shocks. For cleaning, favor a bath of lukewarm water with mild soap and a soft brush. Ultrasonic and steam cleaning are not recommended, as they could damage the stone.

Aquamarine
Aquamarine is a precious gemstone belonging to the beryl family, famous for its light blue to blue-green color, evoking the sea. It derives its hue from traces of iron in its crystalline structure, and its transparency and purity make it a gemstone particularly prized in jewelry. The name "aquamarine" comes from the Latin aqua marina, meaning "sea water," which perfectly reflects its crystalline and soothing color. The main aquamarine deposits are found in Brazil, Zambia, Mozambique, and Pakistan.Technical Properties Hardness: 7.5 to 8 on the Mohs scale, making it relatively resistant to scratches and ideal for everyday jewelry. Density: 2.70 g/cm³ Cleavage: perfect, but rarely observable. Crystal form: hexagonal Resistance: excellent resistance to heat and light, although like all precious stones, it must be protected from violent impacts. Working Methods and ShapingAquamarine is cut primarily in facets to maximize its brilliance and transparency. The most common cuts include round, oval, cushion, and emerald cut, which is the historical cut for this stone. Its exceptional brilliance and clarity allow for delicate and sophisticated creations, often in refined jewelry such as rings, necklaces, and earrings. Larger aquamarine crystals are often cut into faceted stones, while smaller stones can be cut into cabochons for a softer effect.Durability and Ethical SourcingAquamarine deposits are primarily located in Brazil, Mozambique, Zambia, and Pakistan. Although this gemstone is fairly abundant, environmental concerns related to precious stone extraction remain present. Ethical sourcing initiatives and certifications of responsible practices (such as the "Fairmined" label) exist to ensure that aquamarine extraction complies with social and environmental standards.
Alexandrite
Alexandrite is a very rare and unique precious stone, recognized for its ability to change color depending on the light. In natural light, it displays green to blue-green hues, while in artificial light (incandescent), it shifts from purple-red to violet. This stone is a variety of chrysoberyl, a mineral composed of aluminum and beryllium, and its optical phenomenon, called the alexandrite effect, is due to the way it absorbs light. This stunning color transformation makes it one of the most sought-after and precious stones. Alexandrite is one of the most fascinating and coveted stones in the world of jewelry, largely because of its unique optical phenomenon and its rarity.Technical Properties Hardness : 8.5 on the Mohs scale, which makes it a fairly scratch-resistant stone. Density : approximately 3.7 g/cm³. Cleavage : very weak, which makes it less likely to break. Crystal form : orthorhombic Refraction : alexandrite exhibits weak birefringence, which contributes to its luster and brilliance. Optical properties : the main characteristic of alexandrite is its color change depending on the light source, which is due to its ability to filter certain wavelengths of light. Working and Shaping MethodsSince alexandrite is a relatively hard stone, it can be cut into many shapes, including oval, round, cushion, emerald, and princess cuts. Jewelry artisans favor cuts that allow them to maximize the stone's color-changing effect. Alexandrite is generally set in fine jewelry such as rings, pendants, and earrings, often in gold or platinum to enhance its brilliance. Being a rare and precious stone, it is often used in high jewelry creations.Durability and Ethical SourcingAlexandrite deposits are extremely rare, with the most famous sources located in Russia. However, deposits have also been discovered in Brazil, Tanzania, and Africa. High-quality natural alexandrite is highly prized on the market and can command high prices. The rarity of alexandrite means that ethical sourcing is particularly important, and buyers should ensure they source from mines that follow responsible and sustainable practices.
