How to Identify Real Crystal: A Comprehensive Guide

Introduction

Crystals, with their captivating beauty and alleged therapeutic properties, have garnered immense popularity in recent years. However, the proliferation of fake crystals has made it challenging for consumers to discern genuine ones. This guide equips you with the knowledge and techniques to confidently identify real crystals.

Physical Properties

1. Hardness:

Crystals exhibit varying levels of hardness on the Mohs scale, ranging from 1 (softest) to 10 (hardest). For instance, diamond (10) is the hardest known substance, while talc (1) is the softest. Identifying a crystal’s hardness can provide valuable insights into its composition.

2. Refraction:

Crystal’s refractive index measures the extent to which light bends when passing through it. Different crystals have distinct refractive indices, affecting their appearance and luster. When light enters a highly refractive crystal like diamond, it undergoes significant bending, creating the characteristic sparkle and brilliance associated with the gem.

3. Crystal Structure:

Crystals possess defined crystal structures, with atoms arranged in specific geometric patterns. This structure determines their external shape, cleavage planes (where they break along), and other characteristics. For instance, quartz crystallizes in a hexagonal prism shape, while calcite forms scalenohedral crystals.

4. Specific Gravity:

Specific gravity measures a crystal’s density relative to water. Different crystals have varying specific gravities, which can be used for identification purposes. For example, pyrrhotite, an iron sulfide mineral, has a specific gravity of 4.6, while quartz has a specific gravity of 2.6.

Optical Properties

1. Color:

The color of a crystal stems from the absorption and reflection of light within its structure. While some crystals display pure, vibrant colors, others appear colorless or have a pale hue. Color can be an indicative but not definitive characteristic, as some synthetic crystals may be treated to mimic the colors of natural ones.

2. Luster:

Luster refers to the surface appearance of a crystal when it reflects light. Terms used to describe luster include metallic, vitreous, pearly, and greasy. For example, pyrite exhibits a metallic luster, while fluorite has a vitreous luster.

3. Transparency:

Transparency measures the degree to which light can pass through a crystal. Crystals can be transparent (clear), translucent (slightly cloudy), or opaque (does not transmit light). Determining a crystal’s transparency can aid in identifying the mineral’s composition.

4. Optical Effects:

Certain crystals exhibit optical effects such as chatoyancy (cat’s eye effect), asterism (star effect), and fluorescence (glowing under ultraviolet light). These effects arise from the crystal’s internal structure and impurities and are valuable for identification purposes.

Other Identification Methods

1. Scratch Test:

The scratch test involves gently scratching the surface of the crystal with a material of known hardness, such as a piece of glass or metal. If the crystal scratches, it is likely not genuine.

2. Thermal Conductivity:

Crystals vary in thermal conductivity, which refers to their ability to conduct heat. Real crystals tend to have a lower thermal conductivity than synthetic ones, resulting in a noticeably cooler feeling to the touch when handled.

3. Electrical Conductivity:

Some crystals, such as quartz and calcite, exhibit piezoelectric properties, meaning they generate an electrical charge when subjected to mechanical stress. Real crystals with these properties can be identified using a simple multimeter.

Comparison of Real and Fake Crystals

Tips and Tricks

• Purchase crystals from reputable dealers or certified gemologists.
• Avoid crystals with perfect shapes or overly vibrant colors, as these may be signs of synthetic or treated crystals.
• Conduct the scratch test and thermal conductivity test to verify the authenticity of the crystal.
• Consider using a polariscope to examine the crystal’s optical properties.
• Consult with a professional gemologist for definitive identification.
