Silver tone science themed charms, perfect to add to my pendant necklaces, and even bracelets and key chains! I have several neurotransmitters, DNA, chemistry atoms, a few laboratory tools, an astronaut and a planet, and a robot thrown in for fun. Each charm will be added to your jewellery purchase using 1 or 2 sterling silver jump rings, as shown in the 5th and 6th photos. If you buy a charm without jewellery, 1 sterling jump ring 6 mm in diameter will be added; a sterling silver split ring can be used on request instead. The charms are nickel & lead free, made of a silver-tone metal alloy. The available charms are as follows, with measurements: A. Beaker/Flask, 26 mm long (1 inch)

B. Chemistry Atom, 33 mm long (1 1/4 inches)

C. Ringed Planet (like Saturn), 13 mm long (1/2 inch) by 20 mm wide (4/5 of an inch)

D. Robot, 19 mm long (3/4 of an inch)
