GEMSTONES
SAPPHIRE
The sapphire, like the ruby, belongs to the corundum family. It is renowned primarily for its intense blue colour. Sapphires also exist in yellow, orange, pink, purple, green, and even colourless varieties, all represented in The BrandZ collection. Thanks to its exceptional hardness surpassed only by diamond, the sapphire is ideally suited as a gemstone for jewellery.
GEMSTONES
RUBY
The ruby is the red variant of the mineral corundum and obtains its colour from the trace element chromium. It ranks among the world's most valuable gemstones. In fine quality, rubies are exceptionally rare and, at sizes over 3 carats, can command prices exceeding those of diamonds. The BrandZ offers an extensive spectrum of rubies.
GEMSTONES
AQUAMARINE
The colours of aquamarine, which belongs to the beryl family, range from subtle light blue to intense green-blue. The more vivid the colour of an aquamarine, the more valuable it is. The BrandZ aquamarines predominantly originate from Brazil and Mozambique.
GEMSTONES
EMERALD
The oldest known emeralds date back 2.6 billion years. They belong to the beryl gemstone group, which is colourless in its pure state. Traces of chromium and vanadium primarily give emerald its vibrant green hue. The BrandZ maintains an extensive inventory of emeralds from Colombia, Brazil, and Zambia.
GEMSTONES
BERYL
In trade, only the greenish-yellow and green stones are referred to as beryls. For all other beryls, the variety names are used. The BrandZ also carries the wonderfully radiant golden beryl in its collection.
GEMSTONES
MORGANITE
The morganite, another well-known representative of the beryl variety, sparkles from clear pink to delicate peach tones. The BrandZ will be happy to advise you on which shade suits you best. A morganite from deposits in Brazil, Madagascar or Afghanistan will be among them.
GEMSTONES
TOURMALINE
Tourmalines surpass all other gemstones in their diversity of colours. The name derives from the Sinhalese expression "tura mali," meaning "stone with mixed colours." Tourmalines are exceptionally well-suited for custom jewellery design, which The BrandZ and its designers are delighted to create for you.
GEMSTONES
PARAIBA TOURMALINE
With its colour spectrum ranging from neon green and blue to turquoise tones, the Paraíba tourmaline is a star among coloured gemstones. Its sparkling hues are due to copper content, found only in limited deposits in Brazil and Mozambique. This rarity makes the Paraíba tourmaline a true exclusive and a secure investment. The BrandZ maintains direct relationships with the mine owners.
GEMSTONES
RUBELLITE
The rubellite belongs to the colourful family of tourmalines. Its colours shine in beautiful shades from red to vibrant pink. While most "red" tourmalines exhibit a more or less pronounced brown tint under artificial light, the rubellite's colour remains stable across different light sources. The BrandZ is pleased to demonstrate this quality for you.
GEMSTONES
TSAVORITE
In 1967, this breathtaking gemstone was discovered in northeastern Tanzania, near Tsavo National Park. It belongs to the garnet family and sparkles in the most beautiful green tones. Its intense fire is due to its high refractive index. The BrandZ also offers rare pieces over 3 carats.
GEMSTONES
DEMANTOID
The demantoid belongs to the large gemstone family of garnets. Its name derives from the Dutch and means "diamond-like." Due to its rarity, it ranks among the most precious gemstones. Demantoids over 8 carats are true rarities and can be sourced by The BrandZ only thanks to its strong connections.
GEMSTONES
MANDARIN GARNET
At the end of the 20th century, orange garnets of unprecedented colour intensity and luminosity were found in Namibia along the border river to Angola, the Kunene River. After having many names, it was agreed upon to name it Mandarin Garnet. The spectacular specimens of The BrandZ come from Namibia and the later discovered deposits in Nigeria.
GEMSTONES
SPINEL
Spinels have often been mistaken for rubies throughout history. For instance, some gemstones from various crown jewels, erroneously regarded as rubies, were later identified as spinels. This does not diminish their value in any way. The BrandZ's fine specimens primarily originate from Tanzania, Burma, and Vietnam.
GEMSTONES
TANZANITE
Tanzanite derives its name from the East African nation of Tanzania, the only place in the world where this gemstone has been found to date. It was first discovered in 1967 by a few Maasai herders. The BrandZ suppliers, through their stakeholdings, can guarantee fair and controlled mining practices.
GEMSTONES
CHRYSOBERYL
There are only a few chrysoberyl crystals that are clear and transparent enough to be cut into gemstones for jewelry. The BrandZ also offers the chrysoberyl cat’s‑eye variety in its collection. Due to light refraction within the fine, parallel hollow channels, a rippling shimmer of light appears across the gemstone.
GEMSTONES
ALEXANDRITE
The precious alexandrite has the remarkable property of displaying different green tones in natural light and a palette of violet and red tones under artificial light. It belongs to the chrysoberyl gemstone variety and is the chameleon in The BrandZ collection.
GEMSTONES
IMPERIAL TOPAZ
The topaz exists in many different colours. The imperial topaz is by far the rarest and most expensive variety in the topaz family. Its colour palette ranges from peach and pink to rare violet tones. The BrandZ offers rare individual pieces as well as beautiful pairs, perfectly suited for earrings.
GEMSTONES
CITRINE
The citrine, like the amethyst, belongs to the quartz family. Natural citrines are very rare. Often, amethysts are heat-treated, transforming their colour to orange-yellow. The BrandZ declares all stones strictly in accordance with CIBJO trade organisation guidelines.
GEMSTONES
AMETHYST
The amethyst's colour ranges from very light, slightly pinkish tones to deep violet. The most sought-after pieces in The BrandZ collection feature deep violet hues and predominantly originate from Africa.
