Antique Georgian Friendship Fede Memorial Memento Mori ring gold engraved (7439)

Antique friendship  fede Memento Mori  Memorial ring band.  Gold. See below for date (preceding 1846). Unisex - can be worn by a man or a woman. 

Measurements: Weight is 3.8 grams. US size 9.75. 

Description : A large band. The Bezel of the ring is formed by a pair of clasping hands. One hand is a woman's and one a man's. The man is clasping the hand of the woman - her hand is on top, while his hand is 'upside down', below. The wrist of the woman has a raised cuff behind a bracelet. Her ring finger wears a ring. The man's wrist also has a raised cuff, from which protrudes a wavy raised adornment, probably describing a lace frill. 
Behind each raised cuff is a gold sphere/button. Gently pulling this button, levers the entire side up and open, revealing a compartment, still containing hair. The edges can be gently tucked back in to close the ring. 

Inside the shank is engraved Zum Andenken von A. Tarecki d. 28/2 46. Zum Andenken translates to 'In Memory of' from German to English.
Back of ring, on outside of shank is a red gold section of the band that forms a plaque reading Julie with a little scrolling squiggel next to it. The gold of this section conforms to the gold on the inner band.  

Age: Often, we know the age of a ring via a hallmark, or a specific style. In this case, we have a tantalising partial date, but it does not tell us the century. At latest 1846, the style of the ring dates it to an earlier century, but which one? Any year from the Renaissance onwards is a possibility and open to your judgement until further evidence or academic opinions weigh in. We are calling the ring "Georgian" as it is most likely at least from that era. 

Marks and Metal:  As is to be expected, there are no hallmarks on the gold/metal. The engraved inscriptions are described above.   As is common in very old, antique jewelry, the metal is not homogenous. It tests at different purity of gold, depending on where you test it: The hand tests as 14k; In general, the outer band tests as 10k with the inner band testing at 8k. 

Condition: Minor wear commensurate with age and use.  Please see enlarged pictures and don't hesitate to ask questions which we will do our best to answer.   

THE STORY: 
Until modern times, it was much more common to give jewelry as gifts, marking all and every occasion during the course of life. Two meaningful types of jewelry were Momento or memorial rings and friendship or Fede rings:
Long ago, it was customary to earmark money in one's will for making into memorial jewelry to be given to family and close friends as a remembrance of the one who had passed away.  Usually this jewelry was in the form of a ring, engraved with the name and dates of the deceased. The inscription which tranlsates to 'in memory of' and then the name and date, make this clear that it was a memorial ring of this type.
Since Ancient Roman times, thousands of years ago, it was customary to give friendship rings - marking either romantic or platonic friendship. Known as Fede rings, they were in the form a pair of clasped hands.
This ring combines all of the above romantic and friendly customs, sadly no longer much practised in our age of relative isolation. We know the name of the deceased, but we do not know who the ring was given to. Was it a man - as evidenced by the large size? Was it Julie or did Julie come later?  Obviously someone close to the deceased and beloved, as evidenced by the clasped hands. 
What we don't know is who the recipient was, nor who owned the ring in the hundreds of years since it was given. Please see discussion of the dates and age above.
