Tools Needed for Identification
Before beginning the identification process, it's essential to gather the necessary tools. These tools include a magnifying glass or jeweler's loupe, a bright light source, and a black cloth or backdrop to enhance color visibility.
Step-by-Step Guide to Spotting Genuine Black Onyx
Step 1: Examine the color - Hold the black onyx under a bright light source and observe its color. Genuine black onyx should appear uniformly black, without any grays, browns, or other colors.
Step 2: Check for banding - Look for thin bands or layers on the surface of the black onyx. These bands should be parallel and evenly spaced.
Step 3: Evaluate the texture - Feel the surface of the gemstone. Genuine black onyx should have a smooth and glossy texture, free from any roughness or pitting.
Step 4: Assess the transparency - Hold the black onyx against a light source and look for a slight glow. This glow indicates transparency and confirms the authenticity of the gemstone.
By following these steps and making the necessary observations, you can confidently determine whether your black onyx is genuine or an imitation.
Differentiating Between Real and Fake Black Onyx
Although the process described above helps in spotting genuine black onyx, it is equally essential to be aware of common imitations and the key differences they present. Let's explore some popular imitations and the telltale signs that set them apart from genuine black onyx.
Common Imitations of Black Onyx
One of the most common imitations of black onyx is dyed chalcedony. This type of imitation is created by enhancing the color of white or light-colored chalcedony using dyes or other coloring agents. The result is a stone that resembles genuine black onyx but lacks its natural coloration.
Another imitation to be aware of is glass. Black glass stones are often used as a substitute for black onyx due to their similar appearance. However, glass lacks the natural composition and physical properties of genuine black onyx.
Key Differences Between Genuine and Fake Black Onyx
To differentiate between genuine black onyx and imitations, consider the following key differences:
- Genuine black onyx will exhibit banding or layers, while imitations may lack this characteristic.
- Black onyx should be relatively heavy compared to imitations made from lighter materials like glass.
- Imitations may have a grayish or brownish undertone when held under a light source, compared to the uniform black color of genuine black onyx.
- Imitations may lack the faint glow when viewed against a light source, indicating a lack of transparency.
Being aware of these differences will help you make an informed decision when purchasing black onyx and avoid being deceived by imitations.
