Turquoise, azurite, malachite and chrysocolla are all copper bearing minerals that form in the oxidized, upper zones of copper ore deposits. While variscite is not a copper-based mineral like the others, it is closely related to them in mineral families and frequently occurs in similar environments. Eilat stone is not a single mineral, but rather a naturally occurring, heterogeneous mixture of chrysocolla, malachite, azurite, and turquoise.

Copper Siblings

Turquoise is a copper aluminum phosphate. It shares the same copper genesis as azurite, malachite, and chrysocolla, which is why it often features similar bright blue and green tones. Inclusions of azurite, malachite, and chrysocolla are not uncommon in turquoise pieces.

Azurite, a deep, royal blue copper carbonate, absorbs water over time which naturally alters it into malachite, a vibrant green copper carbonate. They can often be found growing together in a swirling pattern.

Chrysocolla is a vibrant blue-green copper silicate. Because it forms in the same copper-rich environments, it is often found weaved together with malachite and azurite.

The Look-Alike

Variscite forms in similar sedimentary and phosphate-rich environments, however it is an aluminum phosphate mineral rather than a copper-based mineral. Visually similar to turquoise, variscite is often opaque, bright green or blue-green. It is commonly compared or confused with turquoise.

Durability and Uses

Turquoise naturally ranks 5 to 6 on the Mohs scale of hardness. In order to make it more durable, most turquoise on the market is hardened (or "stabilized") with electricity and/or polymer. Stabilization of turquoise is viewed as an accepted, regular practice in the lapidary industry and is not to be confused with "dying" material. Dyed (or artificially colored) material is not viewed as favorably among dealers and collectors. Stabilized turquoise can be worn in everyday jewelry.

With azurite and malachite ranking 3.5 to 4 on the Mohs scale of hardness and variscite ranking 4 to 5, all are recommended for use in earrings or pendants. If set in a ring, wear variscite rings with care, and azurite and malachite rings only delicately for special occasions.

Chrysocolla is known to vary in durability, ranging from 2 to 7 on the Mohs hardness scale,based entirely on the amount of silica (or quartz) in the stone's makeup. Generally, dark navy blue pieces are softer, while cyan, green, and blue-green pieces are harder.  For this reason, pendants and earrings are always safe, while some pieces can be worn in every day rings.

Eliat stone, also, varies in hardness from 2 to 7 on the Mohs hardness scale depending entirely on the combination of minerals in a stone's makeup. Earrings and pendants are, always a safe option when considering Eilat stone jewelry.

Stone Cleaning

Avoid all chemical jewelry cleaners when cleaning any of these stones.

Chrysocolla with a high silica content (referred to as agatized) may withstand chemical silver cleaner, but do not use if you are not 100% certain your stone is agatized.

Clean azurite only with mild to cool water and a soft bristled toothbrush.  A jeweler's rouge cloth on only the metal is the ideal method.

Turquoise is a porous stone that can absorb any harsh chemical used. For this reason, focus only on cleaning the metal around your stone.

Clean Eilat stone jewelry with a simple polishing cloth or mild soap and water if necessary. 

Clean variscite jewelry with a silver polishing cloth while avoiding the stone in order to preserve the stone's polish.
