Hackmanite
Hackmanite is a variety of sodalite known for tenebrescence, a reversible color change caused by exposure to ultraviolet light.
Depending on its origin and condition, it may appear:
- White.
- Pale gray.
- Pink.
- Lavender.
- Violet.
- Deep purple after ultraviolet exposure.
The intensified color may gradually fade when the stone is removed from ultraviolet light.
Hackmanite is traditionally associated with:
- Personal change.
- Self-discovery.
- Adaptability.
- Revealing overlooked qualities.
- Responding constructively to new information.
Its relationship with the wider sodalite family helps explain its color, composition and appearance.
Halite
Halite is natural sodium chloride—the mineral form of salt.
It commonly forms cubic crystals in:

- White.
- Pink.
- Orange.
- Blue.
- Purple.
- Gray.
Halite is traditionally associated with:
- Purification.

Halite dissolves readily in water and can absorb moisture from humid air. It should be kept dry in a stable display container.
Do not rinse halite, place it in an aquarium or use decorative specimens as edible salt.
Harlequin Quartz
Harlequin quartz is clear or translucent quartz containing red, orange, brown or dark mineral inclusions.
The inclusions may consist of:

- Goethite.
- Other iron-rich minerals.
Its traditional meanings include:
- Focus.
- Balanced action.
- Motivation.
- Emotional awareness.

Some sellers use “harlequin quartz” and “fire quartz” interchangeably, while others reserve the name for material containing both red and darker inclusions.
Learn about its host mineral in the quartz family guide.
Heliodor
Heliodor is a yellow to greenish-yellow variety of beryl.
Its color commonly ranges from:
- Pale lemon yellow.
- Golden yellow.
- Yellow-green.
- Warm honey tones.
Heliodor is traditionally associated with:
- Confidence.
- Clear direction.
- Optimism.
- Independent decision-making.
- Following through on plans.
It belongs to the same mineral family as emerald, aquamarine, morganite and goshenite. Explore these relationships in the beryl guide.
Yellow heliodor may resemble citrine, but the two have different crystal structures and physical properties. The guide to heliodor vs. citrine explains the main identification differences.
Color, clarity, size and treatment can influence cost, as covered in the heliodor price guide.
Hematite
Hematite is an iron oxide mineral that may appear metallic silver-gray, black, reddish brown or earthy red.
Regardless of its external appearance, natural hematite usually produces a reddish-brown streak when rubbed against an unglazed porcelain surface.
Hematite is traditionally associated with:
- Grounding.
- Determination.
- Practical thinking.
- Stability.
- Completing demanding responsibilities.
Its traditional spiritual uses are explored in more detail in the guide to hematite healing properties.
Some polished hematite sold in jewelry is synthetic or combined with other materials. Use the guide to buying real hematite when comparing natural and manufactured pieces.
For routine care, follow methods suitable for iron-rich material in How to Cleanse and Charge Hematite.
Herkimer Diamond
Herkimer diamonds are naturally double-terminated quartz crystals historically associated with Herkimer County, New York.
Despite the name, they are quartz rather than diamond.
They commonly show:
- Excellent transparency.
- Two naturally pointed ends.
- Internal fractures.
- Carbon inclusions.
- Small fluid or mineral inclusions.
Herkimer diamonds are traditionally associated with:
- Clarity.
- Personal awareness.
- Focus.
- Amplifying intentions.
- Recognizing overlooked details.
The term is sometimes used broadly for double-terminated quartz from other locations. Provenance and seller disclosure matter when locality is important.
The guide to buying a real Herkimer diamond explains what to examine before purchasing.
Hessonite Garnet
Hessonite is an orange, honey-colored, reddish-brown or cinnamon-colored variety of grossular garnet.
It may display a distinctive internal appearance sometimes described as:

- Peach.
- Pink.
- Red.
- Pale green.
Heulandite is traditionally associated with:
- Reflection.
- Emotional openness.
- Patience.
- Examining recurring patterns.
- Creating space for change.
Its crystals are relatively soft and have good cleavage, making them vulnerable to scratching and impact.
Heulandite should not be routinely soaked. Its relationship with other porous minerals is explained in the zeolite guide.
Hiddenite
Hiddenite is a green variety of spodumene.
Its color may range from:
- Pale yellow-green.
- Mint green.
- Emerald-like green.
- Medium green with visible color zoning.
Hiddenite is traditionally associated with:
- Emotional renewal.
- Growth.
- Hope.
- Compassion.
- Beginning again after disappointment.
The stone has distinct cleavage and can fracture if struck. Some green material may also fade after prolonged exposure to strong light or heat.
Fine natural hiddenite is uncommon, and some similarly colored stones may be sold under the name incorrectly. The hiddenite price guide explains the factors that affect value.
Hollandite Quartz
Hollandite quartz is clear or translucent quartz containing dark hollandite inclusions.
The inclusions may form:
- Tiny stars.
- Bursts.
- Crosses.
- Radiating clusters.
- Dark suspended dots.
These distinctive patterns make hollandite quartz popular among inclusion-quartz collectors.
It is traditionally associated with:
- Perspective.
- Inner organization.
- Recognizing patterns.
- Mental focus.
- Understanding interconnected ideas.
Natural internal fractures and exposed inclusions can make some specimens more vulnerable than ordinary solid quartz.
Honey Calcite
Honey calcite is a yellow, golden or amber-colored variety of calcite.
It may appear:

- Cloudy.
- Banded.
- Waxy when polished.
Honey calcite is traditionally associated with:
- Motivation.

- Decision-making.
- Learning.
- Turning ideas into manageable actions.
Calcite is soft and acid-sensitive. Keep honey calcite away from vinegar, citrus juice, harsh cleaners and harder stones.
Explore related varieties in the calcite guide.
Because dyed or mislabeled stones may resemble honey calcite, review the guide to buying real honey calcite before purchasing.
Howlite
Howlite is usually white or cream with gray, brown or black web-like veining.
It is traditionally associated with:
- Patience.
- Calm communication.
- Self-awareness.
- Slowing impulsive reactions.

Hyalite is a transparent, translucent or milky variety of common opal with a glassy appearance.
It often forms:
- Rounded coatings.
- Botryoidal surfaces.

Some hyalite fluoresces bright green under ultraviolet light because of trace elements within the material.
Hyalite opal is traditionally associated with:
- Openness.
- Creativity.
- Curiosity.
- Fresh perspective.
- Recognizing subtle possibilities.
Natural hyalite can be delicate and may develop cracks when exposed to sudden environmental changes.
Explore its broader mineral family in the opal guide.

- Herkimer diamond.
- Hessonite garnet.
- Hiddenite.
- Honey calcite.
- Howlite.
- Hypersthene.
Durability differs considerably.
Hessonite garnet and heliodor are generally better suited to regular jewelry than soft halite, heulandite or honey calcite.
Hiddenite and hypersthene require protection from impact because of cleavage or brittleness. Howlite can scratch, absorb dyes and react to chemicals.

Care and Safety for H Crystals
H crystals require material-specific care:
- Halite: Keep completely dry because it dissolves in water.
- Hackmanite: Protect from prolonged intense light when preserving its current color matters.
- Heliodor: Avoid hard impacts and professional cleaning methods that have not been approved for the stone.
- Hematite: Dry it after cleaning and check whether the piece is natural, coated or manufactured.
- Herkimer diamond: Protect exposed points and internal fractures.
- Heulandite: Avoid soaking, abrasion and rough handling.
- Hiddenite: Limit strong light, heat and sudden impact.
- Honey calcite: Keep away from acids and harder stones.
- Howlite: Avoid dyes, oils and aggressive cleaners that may enter its pores.
- Hyalite opal: Protect from rapid temperature and humidity changes.
- Hypersthene: Avoid ultrasonic cleaners and strong blows.
Store fragile specimens in padded compartments rather than loose bags where harder stones can strike them.
