Beryls can range from colourless to black, and crystals can range in size from single carats to extremely large and flawless examples displayed in museums. Transparent specimens are referred to as ‘precious beryl’. These include the popular emerald and aquamarine and the rarest – red beryl, as well as morganite, golden beryl and heliodor.
Golden beryl had a hardness o 7.5 to 8 on Moh’s scale. Golden beryl gemstones are an excellent choice for jewelry due to their hardness, toughness, and resistance to corrosive substances. Golden beryl is almost always untreated. The finest Golden Beryl come from Asia, Africa and South America.
Golden beryl can range in colour from pale yellow, orange-yellow and deep golden orange. Sometimes also called Heliodor which is the correct term for greenish-yellow beryls.
Golden beryl occurs from transparent to opaque and top values go to clarity first, with colour a close second. When cut and polished, golden beryl has an attractive vitreous to waxy luster.
Golden beryl is usually faceted to display its brilliance. Golden beryl is available in a variety of shapes and cutting styles. Traditional shapes are most common, including ovals, pears, rounds and cushions, and fancy shapes are also readily available, such as trillions, hearts and briolettes. Golden beryl is an excellent material used frequently for gemstone carvings and ornamental designs. It is rarely cut as a cabochon unless it possesses asterism (star effect) or chatoyancy (cat’s eye effect).
Since beryls are available in large sizes, there is usually no incremental price increase for large beryls. All beryls hold the same value above about three carats. (Red beryl is an exception).
Precious beryl is sensitive to pressure and vulnerable to household chemicals. Beryl is one of the more durable gemstone types, but it does still require some careful handling. Avoid wearing beryl jewelry when working with harsh chemicals or household cleaners, such as bleach or acid. When cleaning beryl gemstones, warm soapy water and tissue or a soft cloth can be used. Be sure to rinse the stones well to remove all soapy residue. It is best to avoid the use of ultrasonic cleaners.
Remove precious beryl jewelry when exercising, cleaning, playing sports or engaging in vigorous physical activities. Beryl can easily scratch other gems, such as common quartz and feldspar, so avoid direct contact with other gem types. To prevent scratches, store beryl separately and away from gemstones and gemstone jewelry, such as topaz, sapphire and diamond. You can store your gemstones or gemstone jewelry by wrapping them in soft cloth and placing them into a fabric-lined box.
