The Monet necklace is silver tone color.  It has a snap lock clasp.  The length is 16".  Swirl type design sections of 12.  Unique and an older Monet necklace.

There's three gold tone necklaces - one has links that look like hearts with a snap lock clasp.  It is 17".  Next one is gold tone with five leaves at the end of the necklace with the one leaf dangling.  It has a lobster type clasp.  Length is 16" with a 3" extender.  There is some mark on this one!  The last gold tone necklace is 54" with no clasp.  You can style the way you wish to wear.  Small chain link with 4 inserts of 2 1/2" long that has three squares with an Asian look design to me.  

Next, is a unique beaded necklace with teeth like adornments on it not sure if these are real (could be maybe?) or faux.  Has a barrel clasp.  It is 18".  The 15 teeth on the necklace have a pastel orange color look.  

There's another necklace that looks to have glass beads.  Amethyst color.  Lobster clasp.  It is 19" long.  

There's a necklace with partial suede and chain link that has lots of dangling stones.  Lobster clasp.  It is 18".  There are 25 dangling colorful stones on this necklace.  

Last, gold and silver tone color large and small circle necklace.  Has a toggle closure.  It is 35" long.  Adjust it any size you want.  

Nice lot.  I did only see the one necklace marked Monet, but there is another one that has some sort of mark on it.  All are in very good condition.  Clasps working great.  Great to keep or give as a gift.  Shipping is $8.65.  Thanks for looking.
