Howlite and Moonstone: Are They the Same? Why Does My Moonstone Look Exactly Like Howlite?

Howlite and moonstone are not the same thing. These two minerals belong to different families and possess distinct properties and appearances. This article will explore the differences between Howlite and moonstone, why they might appear similar, and how to distinguish between them.

Composition and Appearance

Howlite:

Composition: Howlite is a borate mineral primarily composed of calcium and aluminum. Appearance: It typically appears white or gray with black or gray veining, often resembling marble. Howlite is often dyed to imitate other stones such as turquoise. Properties: Known for its calming properties, Howlite is popular in jewelry and as a decorative stone.

Moonstone:

Composition: Moonstone is a feldspar mineral, specifically a type of orthoclase or plagioclase. Appearance: It usually appears translucent with a white, blue, or rainbow sheen known as adularescence. The surface can be milky or clear. An alternative name for moonstone is hecatolite, which may cause confusion. Properties: Associated with intuition and emotional balance, moonstone is often used in spiritual practices.

Why They May Look Similar

The similarity between Howlite and moonstone can be attributed to several factors:

Color and Texture

If your moonstone is milky or has a pale color, it can resemble Howlite, especially if it lacks the characteristic sheen of moonstone. A high-quality moonstone should display the beautiful adularescence, which is a unique feature that distinguishes it from Howlite.

Lighting

The appearance of these stones can change under different lighting conditions, making it difficult to distinguish between them. This effect is particularly noticeable with moonstone, which may appear less vibrant under certain lights.

Quality of the Stones

Low-quality moonstone may not exhibit the typical adularescence, leading to confusion with Howlite. Quality and visual characteristics are crucial in identifying the differences between these two minerals.

If You Cannot Distinguish Between Them

If you are unsure about the authenticity of your stone, consider consulting a gemologist or a reputable jeweler for verification. They can provide accurate identification and ensure you have the correct stone.
