KAlSi₃O₈
Amazonite is a green to blue-green variety of microcline feldspar valued for its distinctive colour, blocky crystal habit and occasional white streaking or perthitic patterning.

SiO₂
Amethyst is the purple variety of quartz, coloured by iron-related defects and natural irradiation within the crystal. With a Mohs hardness of 7, it forms in geodes and mineral veins and is found worldwide, notably in Brazil, Uruguay and Zambia.
Crystal PassportFeaturedOrganic/biogenic gem material — fossil ammonite shell; predominantly carbonate mineral aragonite
AM-uh-lite
Composition
Predominantly CaCO₃ — calcium carbonate in the form of aragonite
Ammolite is a rare, naturally iridescent gemstone formed from the fossilised shells of ancient ammonites. Famous for brilliant flashes of red, green, gold, blue and violet, the finest gem-quality material is associated with the Late Cretaceous Bearpaw Formation of southern Alberta, Canada.

CaCO₃
Aragonite is a calcium carbonate mineral best known for its delicate needles, radiating clusters and pseudo-hexagonal twinned crystals. It shares the same chemical formula as Calcite but has a different internal crystal structure, making it a distinct mineral species.
Crystal PassportFeaturedComposition
Approximately (K,Na)AlSi₃O₈ — feldspar composition varies between specimens
Black Moonstone is a dark-coloured feldspar material valued for its soft silvery, blue, peach or cream flashes of adularescence. Its dramatic contrast between a dark body colour and floating internal sheen gives it a distinctive appearance among moonstone varieties.

MgAl₂O₄
Blue Spinel is a naturally occurring blue variety of Spinel, a magnesium aluminium oxide mineral prized for its rich colour, durability and brilliance.
Crystal PassportFeaturedComposition
SrSO₄
Celestite is a beautiful, delicate mineral best known for its soft sky-blue crystals and striking crystal clusters. Its heavenly colouring and elegant formations make it a popular choice with collectors and crystal enthusiasts.

SiO₂
Citrine is the natural yellow to orange variety of Quartz, prized for its warm lemon, honey and golden colours. Its colour develops within the crystal itself rather than from visible iron staining or surface coatings.
Crystal PassportFeaturedComposition
SiO₂
Clear Quartz is the colourless, transparent variety of quartz, prized for its glass-like clarity, distinctive crystal shapes and remarkable durability. From perfectly clear points to crystals filled with natural veils and inclusions, it is one of the most recognisable and widespread minerals on Earth.

SiO₂
Flower Agate is a modern trade name for a Madagascan chalcedony material filled with soft, flower-like plume formations. Its translucent pink, peach and cream base is crossed by pale internal patterns that resemble petals, buds and blossoms suspended inside the stone.

SiO₂
Garden Quartz is a trade name for Quartz containing natural mineral inclusions that create landscape-like scenes, clouds, mossy patterns and colourful internal formations.
Crystal PassportFeaturedOxide — Quartz with iron-oxide or iron-oxyhydroxide staining/inclusions
GOHL-den HEE-ler KWORTS
Composition
Quartz: SiO₂ Common iron colouring agents may include Goethite: FeO(OH), Hematite: Fe₂O₃, and mixed poorly crystalline iron oxides historically described as “limonite”
Golden Healer Quartz is a commercial name for quartz naturally coloured yellow, gold, honey or brown by iron-rich staining, coatings or inclusions. Its warm appearance is produced by iron oxides and hydroxides rather than by gold or a separate mineral species.
Inside every passport
Composition, crystal system, hardness, formation and observable properties.
Safe checks at home, common imitations and the methods used by professionals.
Stories and folklore presented as cultural history rather than scientific fact.
References are displayed so visitors can see where important information came from.
Our honest approach
We enjoy folklore and traditional crystal beliefs, but we keep them clearly separate from mineral science. They are not medical advice and should never replace professional care.
