Cute Solar System themed necklace.  
both styles are of similar design, only, on one the planets make up a section of the chain of a single strand necklace, and on the other, they hang as a pendant off a similar chain.

both necklaces adjust between 20 to 23" around.
the planets are about 5" total length, 
so that's a 5" section and 18" of chain for the "Strand" version, 
and a 23" chain with a 5" pendant on the "Pendant" version

both styles are mixed media, made of various natural and manmade beads: 

Sun: crackled glass
Mercury:opaque glass
Venus: gold acrylic
Moon: opalite
Earth: beige/turquoise mix howlite
Mars: red glass
Jupiter: striated agate or tiger's eye
Saturn: opaque, slightly peachy glass
Uranus: pale blue dyed quartz
Neptune: manmade lapis
Pluto? nope, not a planet. you don't get Pluto.

you do get a star shaped charm at the end of the chain, at the nape, though. 

if buying more than one, add to cart first and pay all at once to get the best combined shipping rate.
