GEOLOGICAL & MATERIAL BACKGROUND
Howlite – Calcium Borosilicate Mineral
Howlite is a naturally occurring borate mineral, typically white with delicate grey veining. It forms in evaporite deposits through the evaporation of mineral-rich waters.
Howlite Geological Facts:
- Mineral Species: Howlite
- Chemical Composition: Ca₂B₅SiO₉(OH)₅
- Mineral Group: Borates
- Formation: Evaporite environments & boron-rich sedimentary deposits
- Appearance: White to cream with spiderweb-like grey veins
- Hardness: 3.5 (Mohs)
- Origin Locations: USA, Canada, Mexico
Howlite is prized in jewellery for its marble-like patterns and aesthetic.
Abalone Shell – Natural Biogenic Material
Abalone shell is a beautifully iridescent organic biomineral, produced naturally by marine molluscs of the genus Haliotis. Its inner shell layer, known as nacre, displays brilliant rainbow colours.
Abalone Shell Features:
- Type: Biogenic gemstone (organic–inorganic composite)
- Primary Mineral: Aragonite (CaCO₃)
- Formation: Layered microstructure produced by abalones as shell protection
- Optical Effect: Intense iridescence caused by light interference
- Colours: Blue, green, pink, purple, silver, and turquoise swirls
Abalone shell has been used in jewellery for centuries due to its shimmering, ocean-like beauty.
Snowflake Obsidian – Volcanic Glass with Cristobalite Inclusions
Snowflake Obsidian is a natural volcanic glass formed during rapid cooling of silica-rich lava. Its distinctive “snowflake” patterns come from small inclusions of cristobalite, a crystalline form of silica.
Snowflake Obsidian Geological Facts:
- Material Type: Volcanic glass
- Chemical Composition: Mostly SiO₂
- Formation: Rapid cooling of felsic lava during volcanic activity
- Snowflake Pattern: Caused by cristobalite crystal growth within the glass
- Hardness: 5–5.5 (Mohs)
- Appearance: Black base with white or grey snowflake-like patches
This gemstone is admired for its striking contrast and volcanic origins.
