Featured Graduated Coral Necklace- do you recognize the age and type?

Sigh. Somebody please recommend me a book on coral jewelry identification. I bought a two dollar bag of jewelry, and the lady just gave me this. It is 18" long, brass findings, strung on doubled white thread. Most pics are in the shade, one in bright sunlight, no filters/edits used. Shade first, second bright sun, rest shade:

 

See if you can open the attached. Probably easier to read if you download it to your own computer.

 

Yes, thank you! From your link, I found this link, too.

Bronwen, check out this site. It's an entire online PDF that shows corals in the rough and in beads and jewelry.

From all the sites and photos, I am guessing Coralllium Elatius or Satsuma coral.

 

All I know is @Any Jewelry 's antennae just went up! I'd be busily restringing those on proper cording with knots between the beads and adding sterling findings. (LOL) But I'm weird like that.

 

Looks like a great resource. I've downloaded it. Will have to browse it later: cats are calling; I've just finished reading a paper on what the stone called 'jacinth' really is.

 

I need all the help I can get with coral and jade. Those two constantly stump me.

 

I've been wanting to restring my coral beads for safety's sake. The current stringing seems old and fragile. (I discussed my strand HERE.)
Can you recommend any videos and supplies to show me how?

 

Not a clue. I pretty much taught myself. Wheel: reinvented. Check! What you string on depends on the size of the holes, but they sell beading cord with the needle already on it. Larger holes can take larger diameter strings; I often use button thread and just use craft glue on the end. It gets "squished" with my fingers to make it a hair narrower and the glue makes it stiffer and easier to get through a bead hole.

 

It's the knotting (I'm assuming you want knots) that takes practice & a pair of knotting tweezers. You just use the ordinary simple knot, then use the tweezers to get the knot to snug up to the bead as you pull it tight. There are different ways to finish off the ends.

I have a booklet that I found & sometimes still find really useful: "The Basics of Bead Stringing", Debbie Kanan

 

I always used a pin instead of the tweezers, and for waxed cording just bare fingers. They were plain glass beads and it was bone simple stuff.

 

This was helpful... now to buy silk, cement, french wire, and tweezers!

 

One of the great things about bead stringing is that there are infinite do-overs with little loss of materials, mainly the bead cord that has to be cut apart.

 

I some times use a needle inserted into the knot and use that to "guide" the knot close to the bead. Keeping the needle in the knot keeps it from getting tight before I want it to.

 

I use a real needle for that. Beading needles are flexible and tend not to do what I tell them.
