Amethyst, Citrine and Topaz all belong to the commonly known gemstone family - Quartz. These stones tend to form in larger crystals and are known to be slightly more translucent than the other gemstone families. Amethyst and citrine both sit at a durable 7 on Mohs scale, and topaz sits at an 8. This means that these gemstones have good durability and are appropriate for everyday wear.


Chemicals that are commonly found in household cleaners or detergents should be kept away from these gemstones. When cleaning an amethyst, ultrasonic cleaners should be avoided if your amethyst has had fracture fillings or been dyed. Similar to an amethyst,  ultrasonic cleaners are usually safe except in the rare instances where a citrine  has been dyed or treated by fracture filling. When caring for your topaz one should completely avoid the use of ultrasonic cleaners as they are particularly sensitive to temperature changes. 


All three of these quartz gemstones do not fare well in extreme fluctuation of temperature, it is for this reason that steam cleaning should be avoided if you want to retain the gemstones quality. Amethyst is less porous than citrine and topaz and can therefore be soaked in a gentle solution while cleaning. However, excessive exposure to moisture or saltwater can lead to the development of cracks and is to be carefully avoided when cleaning your more porous topaz or citrine. It is of the utmost importance that you use gentle soap  and a lint free cloth to properly clean and dry your quartz stones. A soft brush is not appropriate to use on these stones because of their rating on the Mohs scale of hardness. 



Chips, Scratches & Cracks

Excessive exposure to bright or direct sunlight will fade the vibrant colour of these gemstones, for this reason it is important to store them in separate, softly lined boxes or pouches that are not in direct light. As is the common procedure, it is immeasurably important to store your gemstones separately as the differing levels of hardness will cause them to scratch each other.  The transparency of a gemstone is directly related to its propensity to crack, so avoid sunny spots to keep the cracks at bay. 


You can polish your quartz gemstones with a hair-free leather cloth. Alternatively, you may want to take them to a jeweller where they will be professionally polished. French cerium or facet grade cerium is the most appropriate polish to use on your quartz gemstone pieces and will be sure to help them retain their sheen and lustre.
