Malachite
Malachite is an opaque gemstone with a unique beauty, its dark green tone with varying shades of stripes, reminiscent of vibrant nature. Van Cleef & Arpels selects malachites with a pure, uniform texture. Malachite is used by the family to create many masterpieces, and in the Alhambra® Four-leaf Lucky series and Perlee ™ series, malachite shines in yellow gold.
“malachite” is said to come from the Greek mol, which refers to the mallow plant known for its dark green leaves, or from the word malakh, which means “soft”. Because of its beautiful appearance, malachite became popular in the 19th century, especially in Russia, where it was used to decorate churches and palaces. Malachite was once considered a good luck talisman to protect children and travelers.
Malachite in the passage of time, will gradually tend to natural fade. In order to preserve the unique beauty of the work, the family would like to share with you the following special precautions.
Because malachite is a delicate gemstone by nature, small scratches may appear on its surface. To maintain its luster, malachite must be kept separate from other jewelry and stored separately in a jewelry box with dry lining. Contact with water should be avoided, otherwise it will destroy the protective surface of the gem and weaken its luster.
Repeated contact with water, damp heat, sweat or any corrosive product will damage the malachite surface and make the gemstone white. Van Cleef & Arpel reminds you not to wear the best products in hot and humid environments (bath, SPA, spa, etc.) and to avoid direct contact with products such as perfumes, lotions and alcohol gels (such as hand sanitizer).
External impact may damage the gem, it is recommended that you do not wear the family best in sports activities.
In order to maintain the color and shine of malachite, soft and dry jewelry cloth can be gently wiped.
