I have one that is a pretty Pewter necklace - it's an Angel with Praying hands. I found on it E-Bay - Quantum Jewelry - It opens up into two parts and holds a small pad for a few drops of oil. It also works nicely hanging in the car or truck. Quantum has a bunch of other styles - such as a Rose - a Dragonfly (I think I NEED that one), Praying Hands and more.   They also have some real nice tiny cobalt blue bottles with Pewter workings.

I recently ordered this necklace from an Ebay store:
Metaphysical-Moments.
It's not an aromatherapy shop but is filled with many interesting items.  This necklace is a tiny vial one can fill with aromatherapy oil and wear.  As soon as mine arrived, I filled it with Peace and Calm.   I can smell the soothing scent without even opening the bottle!

  I want one of these interesting items.   It looks sort of like the old fashion Vicks Inhaler but allows one to use their favorite Aromatherapy Oil or blend.  This would be great with Sinus Blend!   This item is available at SomaTherapy Aromatherapy Diffusers .

  I received this nifty and pretty "oil burner" from a friend for my birthday.   It Has a small removable glass bowl and uses a tea light candle.   Add hot water and a few drops of oil - light the candle and inhale!   A friend told me to use Vodka to dissolve the oil when mixing with water in this type appliance or the bath tub!

  My most recently acquired dispenser is called a Scent Ball Aromatherapy Diffusor.   It has a thick pad to drip oil on - plug into an outlet and aroma-ize your space!

I'm not sure what I think of this appliance yet.   I need to try it in a room where I'm NOT mixing oils!

We have one of these cute little clay jars with a tiny cork top.   Essential oils or blends diluted with carrier oil can be added.   The oils soak thru the cork and the unglazed clay at the top to permeate the air.  This style hangs on a cord or can be placed on a table or shelf.   Just be REALLY careful with oil & finished wood.   Aromatherapy oils can strip the finish!!!
Mine is filled with Bergamot Mint Bouquet - sitting on a shelf in the kitchen.   It gently scents the air with a delicate hint of citrus.

  There are also other more expensive "nebulizers" on the market.   These use an aquarium style pump and a glass bulb to dispense oils into the atmosphere.   We had one of these before the fire but didn't get another since.  I'm not sure if it was worth the expense. Although some people swear by them! They don't use heat but dispense the oils into the atmosphere as an invisible mist with air pressure.
