Silver, Curious Victorian pendant in solid silver with a moss agate cabochon. - Pendant

It is a Victorian pendant from the mid-1800s made of solid silver with an oval moss agate cabochon set in it.
Moss agate is a semi-precious gemstone, a variety of chalcedony with mineral inclusions (often manganese or iron) that create patterns resembling moss or ferns.
It is not a true agate in the scientific sense because it does not display the typical concentric bands of that mineral.
The stone is very durable, with a Mohs hardness of 6.5-7, making it suitable for jewelry.
This type of agate has been used for ornamental purposes for centuries and is often cut into flat shapes or cabochons like the one shown.
