I'd never seen anything like this! Per the maker's mark / signature on the clasp, this a Carolee creation. Brass with enamel and glass, I believe. The beaded necklace it's on is a unique pairing.
This shows how the light plays in this piece! 
Everything is in really pristine condition. The Carolee mark / signature is along the edge of the heart closest to the pendant. In the photo I can see it's there but it's difficult to make out. But that's what it says.
Price, including shipping* is $50 .
Above ^, what I created to use, in person, in my home city that's able to be read if people have low vision, and a fun graphic of a telephone very similar to what I had "growing up".

Grate ~ Fully, Mardy
Live and Learn. Learn and Live Better! is my motto. I'm Mardy Ross, and I founded Lumigrate in 2008 after a career as an occupational therapist with a background in health education and environmental research program administration. Today I function as the desk clerk for short questions people have, as well as 'concierge' services offered for those who want a thorough exploration of their health history and direction to resources likely to progress their health according to their goals. Contact Us comes to me, so please do if you have questions or comments. Lumigrate is "Lighting the Path to Health and Well-Being" for increasing numbers of people. Follow us on social networking sites such as: Twitter: http://twitter.com/lumigrate [2] and Facebook. (There is my personal page and several Lumigrate pages. For those interested in "groovy" local education and networking for those uniquely talented LumiGRATE experts located in my own back yard, "LumiGRATE Groove of the Grand Valley" is a Facebook page to join. (Many who have joined are beyond our area but like to see the Groovy information! We not only have FUN, we are learning about other providers we can be referring patients to and 'wearing a groove' to each other's doors -- or websites/home offices!) By covering some of the things we do, including case examples, it reinforces the concepts at Lumigrate.com as well as making YOU feel that you're part of a community. Which you ARE at Lumigrate!
