You will be getting 5 single (1) earrings.  These are for pierced ears.  

Please read the descriptions underneath as I give more details. 

Please check the pictures to see measurements. 

1.  RS 925 Stamped Sterling Silver Cubic Zirconia Single Pierced Hoop Earring 2.5 Grams
It is marked "RS 925" and "925".  Please look at the pictures. The sparkly gems are not diamonds.  They are likely cubic zirconia or crystal.

It is in overall good condition.  It would have been considered in very good condition, but I see 2 gems that are missing (see pictures).  The colors are clean and crisp.  The shape is strong.  This comes from a dry, pet and smoke free environment.

2.  Single Earring 925 Sterling Silver Hook Pierce Dangling Polished Gray Bead Stone

                                                      

The bead is made of some kind of polished stone that has beautiful gradients.  The pierced hook is marked 925 for sterling silver (see picture.  I tried to get a close up of the 925 marking, but the pictures were not very clear as the etching on the hook is small).
It is in overall good condition.  I did not polish the silver as some people like the vintage patina versus shined. The shape is strong.    

3.  925 Sterling Silver Hoop Rhinestone Crystal Pierced Single Earring 
It weighs 3 grams (see picture).  There is some kind of stone that looks like a rhinestone, crystal or cubic zirconia.  

It is stamped/marked inside 925. It is in overall good condition.  The silver is tarnished.  At one point it also had gold plating which is now blackened/tarnished.  I have not polished it as there are some that like the tarnish and older patina.  

4.  925 Sterling Silver Single Stud Earring Pierced Cubic Zirconia

The earring is marked S925.  The earring back is also marked 925.  The gem is unmarked, but it looks like a cubic zirconia.  I don't have a diamond tester so I am calling this a crystal cubic zirconia.  It is in overall good condition.  The stem is a little bent.  There is some tarnish on the bent.  

5.  Pearl stud 14K Gold Filled  Single Earring.
The earring back is stamped 14K GF.  The post is stamped too, but I can't read it fully.   I can see 14K and letters or a symbol after.  It maybe real gold, not gold filled, but since I can't read what is stamped after 14K I'll just call it gold filled like the earring back.   Originally the earring back was paired with another earring so this may actually be real gold.
