This is the Broad Thorn Pendant.
(The ten necessary gemstones are not included.
You can get them for example from this unaffiliated shop:
It has two grommets, one on each end.
So depending on your taste you can wear it upright or sideways.
With 3.9cm length it is quite big and eye catching.
On each of the two twisted sides five 5mm diameter gemstones goes in.
You can even make it multicolored if you'd like,
but single colored designs are definitely more elegant.
Thorns are always assoziated with roses and they have simply to be red
so I've choosen red gemstones for the one depicted above.
It's wonderfully sparkling in bright sunlight.
