Emeralds require more delicate care than most gemstones, as they have a hardness of only 7.5 to 8 on the Mohs scale and almost always contain natural micro-fissures that are filled with oil during processing. It’s a beautiful but sensitive stone: just a moment of inattention while washing dishes or cleaning can cause it to permanently lose some of its brilliance. At BELLER, an emerald and diamond ring starts from PLN 9,500, and proper care ensures that this investment retains its character for decades.
Why emerald is different from other stones
Almost every natural emerald contains tiny, natural fissures within the stone, a result of how it formed deep within the earth's crust under immense pressure. For centuries, jewelers have used delicate oiling, filling these micro-fissures with natural cedar oil, to improve the stone's clarity and brilliance. This is a standard, fully accepted practice in the industry, but it also means that an emerald must be treated differently than a harder, more homogeneous diamond or sapphire.
What to absolutely avoid
The most important rule: never clean an emerald in an ultrasonic or steam cleaner. Vibrations and high temperatures can widen existing micro-fissures or wash out the oil used to fill them, causing the stone to immediately lose clarity, sometimes irreversibly. It's also advisable to avoid sudden changes in temperature, such as taking off a ring just before entering a hot bath after a cool walk, and contact with household chemicals, alcohol, or perfumes applied directly to the hand.
How to clean an emerald safely
The only safe way is to gently clean it with lukewarm water and a little mild soap, without a brush, using only a soft, damp cloth wiped around the stone. After washing, it's worth drying the ring immediately with a soft cloth to avoid leaving streaks on the setting. This is a ritual that takes literally a minute, but makes a huge difference over years of wear.
Storage and daily wear
It’s best to store emeralds separately, away from harder stones like diamonds or sapphires, which can easily scratch them if they accidentally come into contact in the same jewelry box. For daily activities like cleaning, gardening, or working out, it's advisable to remove the ring, as well as in any situation where your hand might strike a hard surface. This stone is meant to dazzle on special occasions and in a calmer rhythm day-to-day, not necessarily at the gym.
