Emerald is a gem quality green "beryl," the same family of stones as blue aquamarine and pink morganite. It is estimated that Colombia produces 70-90% of emeralds on the world market, though in addition, extra-fine grade stones are known to come from Zambia and Brazil. Inclusions are common and expected to be seen in emerald; it is widely accepted practice for gem cutters to conceal inclusions by soaking stones in cedarwood or grapeseed oil. Most stones available on the market have been treated this way.
Though emerald is a hard, scratch resistant 7.5 to 8 on the Mohs hardness scale, we strongly advise to wear emerald rings with care. Stones can be brittle and subject to chipping or breaking on sharp impact. Do not clean emerald jewelry in an ultrasonic cleaning machine or with a steam cleaner. Clean with mild soap, water, and a soft bristled toothbrush. Avoid soaking emerald for long periods of time to preserve any assumed oil treatments in the stone. Should these treatments be compromised, most jewelers can fix them.
Tourmaline is a gemstone well-known for naturally occurring in any shade and saturation of color on the color spectrum. Special terms are assigned to stones of certain colors, such as "rubellite" (red), "indicolite" (blue), "schorl" (black), "dravite" (brown), and "Paraiba" (highly rare electric blue only from Brazil). Occasionally, multiple vivid colors can be present in a single stone, completely independent from one another. These stones are referred to as "bicolor" and "tricolor."
Tourmaline is a hard stone coming in at 7 to 7.5 on the Mohs hardness scale. While stones are safe to use with chemical jewelry cleaner, it is very important to note that tourmaline cannot be put into an ultrasonic cleaner machine. Many tourmalines contain natural liquid-filled inclusions that can burst from ultrasonic vibrations created by such a machine, causing a stone to break. Soap, water, and a soft bristled toothbrush are safe and effective for cleaning tourmaline jewelry.
