The nocturnal (or nocturlabe) is a very old instrument for telling time at night by measuring the stars. While concept is ancient, this design is all original. It is fully functional (all dials move properly) and meant to be worn as a pendant. This is now available for sale, as it has been tested and works nicely.

How to Use the Nocturnal:

The top of the nocturnal is where you see a bit of a ring around a spike. This ring can be strung with a chain and makes it possible to wear the nocturnal as a pendant. When reading the nocturnal, this end of the piece should always be up.

Your first step is to set the outermost dial on the date. The months are shown as letters, with January and December at the top, and the progression of the months running *counterclockwise*. Note that the exact position of the letter actually marks the middle of that month. Look closer at the piece and you will see the line that separates the months between the letters.

Now, hold your nocturnal up to the starry night sky, making sure that the date is still properly set. Locate the North Star centred in the hole in the middle of the Nocturnal. Then use the central dial (the one that looks like a pointer) to point to the two stars at the end of the bowl of the *big* dipper.

Once you have this all set. Look closer at the pointer and you will see that within the pointer is an eliptical ring and within this is a smaller pointer. This smaller pointer points to a roman numeral, which shows you the time.

Note again, that the roman numeral is centred on the middle of the hour. So, if the little pointer points in the centre of the numeral, it is in fact half past.

So now you can tell time at night without a powered time piece. This is great for night owls, vampires, and those who appreciate a gothic or steampunk look.

Note:
The silver material is very bright and shiny. Some designs look much better when deeper parts are blackened. You can do this easily by yourself by putting the silver jewelry in a small glass with bleach for a few minutes. After it turns dark, you can polish it partial with a sponge or a towel.

Please use this template to order a customized signet ring. I can add in initials to one of the other symbols you see here, or create a new symbol to your specifications. Please note that the ring and the impression that it makes are mirror images of each other - letters that look right in an impression come from a seal engraved backwards. If you are trying to design your own symbol precisely, please constrain the drawing to an 3/4" diameter circle, and all lines for raised wax should be a minimum of 0.040" wide. This is like drawing with a dull pencil.

Caution: remove signet rings from your hand before using to make an impression. The ring will get hot. Please be careful to avoid burns when using hot wax.

Quality sealing wax is available through our main website.

In some rare instances, Shapeways stainless steel rings have caused a reaction called "tea staining." This is a (not permanent) brown mark on the skin caused by a chemical reaction with the bronze binder. So far only one customer has reported this, and research shows that it depends on skin chemistry - some people always get it, most people never do. Some solutions for people concerned with this are coating the skin contact area with clear nail polish, gold plating, or getting the ring made in silver.

New contest: send in photos of our seals and rings "in the wild" and win free wax if we use them! Showing the product clearly and creativity are strongly encouraged. By submitting photos, you grant Lightbringer Designs LLC the non-exclusive right to use it as we see fit, you will get photo credit. Private message for details.

Custom seals are also available

UPDATE02/12: The ring has been redone and should hopefully work with silver. As usual any other metal other than silver will give a more faded less detailed result due to the printing process. Get it in silver for the high detailed look, or in other metals for the antique battle worn look. "An assassin's ring with a gap in the bottom to activate a hidden blade. The ring itself is a 8¼ ring size in the US."
