During a visual inspection, several characteristics can help identify chrysocolla. The color of Chrysocolla typically falls within the blue to green spectrum, with shades ranging from light sky blue to deep turquoise. However, it's important to note that other Minerals can exhibit similar colors. Additionally, chrysocolla often displays characteristic patterns, including a mottled or uneven color distribution. It may also be mixed with other Copper minerals such as malachite, azurite, or turquoise. Lastly, evaluating the luster of the Stone is essential. Chrysocolla usually exhibits a vitreous (glassy) to dull luster.

Physical property testing involves assessing specific properties of chrysocolla. One crucial property is hardness, which is measured on the Mohs scale. Chrysocolla has a hardness of 2.5 to 3.5, which means it can be scratched by a copper coin (hardness of 3) but not by a fingernail (hardness of 2.5). It's important to exercise caution during this test to prevent any damage to the stone. Another property to consider is specific gravity, which for chrysocolla ranges from approximately 2.0 to 2.4. Specific gravity tests can be conducted using specialized equipment. Lastly, the streak test involves rubbing the mineral on an unglazed porcelain tile to observe the color of its powdered form. In the case of chrysocolla, the streak is typically white to light blue-green.

Chrysocolla can be difficult to detect by its Chemical composition because it does not have a definite and ‎uniform chemical composition‏.‏‎ Its chemical formula can vary depending on different impurities‏.‏ Basically, any silicate containing copper in a spherical shape, blue to green, cannot be a Rock except ‎chrysocolla‏.‏‎ Chrysocolla can often be identified by its hardness, unique color, and interesting patterns‏.‏ However, depending on the exact composition, the hardness can also vary, but in most cases, chrysocolla ‎stones can be detected by scratch testing‏.‏ Due to its visual similarities in color and luster, Chrysocolla is often confused with Turquoise and azurite‏.‏

Chrysocolla is slightly softer than turquoise‏.‏ Smithsonian is similar in appearance, but its color is slightly lighter and harder‏.‏ Varicose veins are very similar, but they are usually much greener in color and usually much harder than ‎Chrysocolla‏. The most important mines of Chrysocolla ‎are Israel, Congo (Zaire), Chile, United Kingdom, Cluj, Katanga (Shaba), Mexico‏,‏Peru, Russia and the United States (Arizona, Utah, Idaho, New Mexico, Michigan and Pennsylvania).‎ Arizona is now recognized as the best producer of Chrysocolla‏.‏‎ The Timna copper mine was famous in ‎ancient Israel for producing mixed Chrysocolla‏.‏‎ Western Australia is also known for producing chrysocolla ‎azurite quasi-minerals‏.‏ Other notable chrysocolla locations in the world include; Mexico, Peru, Chile, Democratic Republic of Congo (Zaire), Australia, Russia, Cornwall in England, France, and Israel..‏

Advanced analytical techniques can provide further insight into the identification of chrysocolla. Spectroscopic analysis helps identify the specific wavelengths of light absorbed by the mineral, aiding in confirming its identity. X-ray diffraction (XRD) is another technique used to examine the crystal structure of the mineral, providing valuable information for positive identification. Infrared spectroscopy (FTIR) analyzes the specific vibrational modes of the mineral's molecules, creating a unique fingerprint for chrysocolla.

For a definitive identification, it is recommended to consult a professional gemologist. These experts possess advanced tools and expertise, enabling them to accurately identify chrysocolla and differentiate it from minerals that bear a resemblance. When purchasing chrysocolla, especially valuable pieces, there are a few tips to keep in mind. Look for certification from reputable gemological laboratories, as this ensures the authenticity and quality of the gemstone. It is also advisable to buy from trusted dealers or jewelers who can provide provenance information, verifying the source and authenticity of the chrysocolla.
