Rare Georgian Dendritic Agate Riviere
This stunning set of circular agates has been designed to be worn either as a pair of bracelets, or as a single riviere. The dendritic agate stones are beautiful shades, of creams, beiges and browns, set in 15 carat cut down collet settings, modelled in 15 carat gold.
The two tongue clasps are concealed behind matching agate circular sections.
They are presented in their original leather box, lined in cream silk and black velvet, with the company details printed on the silk inside the lid -
'At the blue boar within Aldgate. 1720. Harvey & Gore, 1 Vigo Street, London.'
Dendritic agate is a type of chalcedony from the agate stone family, along with Botswana agate, fire agate, and blue lace agate, among others! While most dendritic agates have a milky body tone, they can also appear translucent to opaque. The milky base creates a beautiful contrast between the dark brown to black inclusions.
The stone’s inclusions, called “dendrites,” are a mixture of manganese or iron oxide minerals that were trapped inside the gemstone when the agate formed.
When a white agate features black dendrite inclusions, the effect emulates a striking wintery scene of snow blanketing tree branches. Who knew that these minerals interacting would create such a picturesque stone?
Chalcedony is a type of quartz that comes in many varieties, including black onyx, carnelian, and sardonyx.
On the Mohs scale of mineral hardness, dendritic agate ranks at a dependable 6.5-7, making it durable enough for everyday wear.
In astrology, dendritic agate is the zodiac stone presiding over Gemini. If you were born between May 21 to June 20, this black and white gem may be the perfect stone to match the dual nature of the Gemini twins.
Geminis are known for being quick thinking and diplomatic, always seeing both sides of a situation. What better gem is there than the “Stone of Plentitude” to accompany compromise?
