Danburite Gemstone Information
About Danburite - History and Introduction
By composition, danburite is a calcium boric silicate and although it is a relatively commonly occurring mineral, large and facetable gemstone quality material is considered especially rare. Today, danburite is one of the lesser-known gemstones and is primarily classified as a collector's gem. It was officially named after the place in which it was first discovered in 1839 - Danbury, Connecticut (USA). Although Danbury is where the mineral was first found, the original mining deposit is now buried deep below the city, and surprisingly, the Danbury mineral deposit never actually yielded any gem quality specimens. The discovery of danburite is credited to Mr. Charles Upham Shephard (1804-1866), an eminent American mineralogist.
High quality danburite occurs with excellent transparency and clarity, and its hardness surpasses that of quartz. Its brilliance can rival that of the finest topaz, but owing to its modest ability to split light into spectral colors (dispersion), it lacks the fire required for most mainstream jewelry, which is the reason why danburite is sought-after by connoisseurs rather than jewelers.
Identifying DanburiteBack to Top
Danburite can sometimes occur encrusted with quartz druzy, and in many cases, quartz may pseudomorph and replace danburite altogether. Danburite can be identified by its unique prismatic crystal structure and through its distinct chemical composition. In most cases, danburite can be easily distinguished from similar materials through its very specific gemological properties, particularly hardness, fluorescence, cleavage and specific gravity (density). Danburite has very little cleavage and a specific gravity roughly the same as jadeite. Danburite tends to be available in large sizes, which is rare with many other colorless gemstones. Colorless rock quartz and topaz are most often mistaken for danburite. However, but topaz is considerably harder than danburite, whilst quartz is slightly softer.
Danburite Origin and Gemstone SourcesBack to Top
Danburite was first discovered in Danbury, Connecticut (USA), but most of the danburite gemstones today originate from Mexico, specifically from Charcas, San Luis Potosi. Other notable gemstone quality deposits of danburite have been found in Bolivia, Burma, Japan, Madagascar and Russia.

Danburite Gemstone and Jewelry Design IdeasBack to Top
With a hardness that surpasses that of quartz, danburite gemstones are perfectly suitable for any type of jewelry application. Due to its brilliance, well-cut danburite is often used as an alternative for diamond or white sapphire. Despite its poor pinacoidal cleavage, it is still an easy material for most lapidaries to work with. Additionally, because of its excellent clarity and the availability of very large sizes, danburite is ideal for creating bold fashion jewelry designs and accessories.
Large pendants, pins, brooches and everyday rings are all excellent ideas for fine quality danburite. Best of all, danburite is rather affordable, especially when compared to other types of colorless stones, but like most large 'white' gemstones, anything over 10 carats is quite rare and will typically be very expensive.
Note: Buy colored gemstones by size and not by carat weight. Colored stones vary in size-to-weight ratio. Some stones are larger and others are smaller than diamond by weight in comparison.
Danburite Gemstone and Jewelry Care and CleaningBack to Top
Although danburite is an exceptionally hard and durable gemstone, it can be easily scratched by many of the other harder jewelry gemstones, such as topaz, spinel and sapphire. Danburite is sensitive to heat and should not be exposed to extreme temperature fluctuations. Avoid the use of steam cleaners as they can permanently damage danburite. Ultrasonic cleaners are typically considered safe, but caution should be taken when cleaning danburite in this manner.
It is best to simply wipe down your stones using a plain soft cloth and warm to room-temperature water. A mild soap or detergent can be used, but be sure to rinse well to remove soapy residue. Avoid wearing danburite with other gems, and always remove jewelry before playing sports, exercising or performing any harsh household chores. When storing your danburite gemstones, store them separately and away from other gems and jewelry. If possible, wrap them in a soft cloth or place them inside a fabric-lined box for extra protection.
