Associated Minerals

1. Associated Minerals include beryl, quartz, spessartine, hematite, pseudobrookite, hausmannite, braunite and topaz.
2. Associated minerals include bixbyite, quartz, orthoclase, topaz, spessartine, pseudobrookite and hematite.
3. It has metallic minerals such as hematite and gemstones such as corundum, chrysoberyl and spinel.
4. They should have bits of amazonite, hematite, pyrite & garnet added.
5. Hematite is believed to be a healing and grounding stone, strengthening the body and lessening life's stresses.

Monte Bianco

1. Monte Bianco produces very rare hematite crystallized in the iron rose habit and associated with pink fluorite and quartz.
2. Approximate Total Gemstone Weight: hematite, 13.36 carats; pink sapphire,.2 carat.

Philips Mine

1. The most abundant primary mineral phases in the mine wastes are hematite, hydrohematite, barite, quartz, muscovite, anorthite, calcite and phillipsite.
2. Hematite as botryoidal formations resembling psilomelane occurs at the Philips Mine and as red coatings of magnetite.
3. Near the BBC Mine there is a deposit of the uncommon amphibole Cummingtonite, along with more fun Hematite and Chrysocolla.

Malachite

1. The base of oxidation was noted at 493m depth and supergene mineralisation comprises hematite, cuprite, azurite, malachite, chalcocite and native copper.
2. Hematite is an important ore of iron, is a mineral appearing as metallic gray, red gray, red brown with a metallic luster.
3. Aventurine is a variety of mineral (usually quartz or feldspar) which is spangled with bright particles of mica, hematite, etc.
4. Labradorite exhibits internal iridescence whereas hematite and sphalerite often show the surface effect.

Sunstone

1. Sunstone is metallic-looking due to sparkling red, orange or green crystalline inclusions (these are hematite or goethite crystals).
2. Inclusions The original sunstone is an oligoclase feldspar colored by platelets of hematite.

Taconite

1. Taconite is a low-grade iron ore, containing up to 30% Magnetite and Hematite.
2. Grey hematite is simply a form of iron oxide Fe2O3. It can form from water but it also can occur in volcanic rocks, metamorphic rocks.

Hardness

1. Associated Minerals are limonite, hematite, quartz, manganite, psilomelane and other manganese and iron oxide minerals.
