Dendritic agate is part of the Quartz family and is recognizable by it's plant like branch style inclusions of iron and magnesium. Moss agate is also form of dendritic agate. This stones hardness is a 7 on the MOHS scale making it a durable stone.  The color can vary from bright white to a lavender color into dark black. I love the drama of the variation in this stone and how it often has a landscape like design. It often feels like nature paintings inside the stone.
 Dendritic agate covers all chakra, is represented as an earth element and known for inner growth and wisdom. Aids in keeping a positive attitude while going through a needed transformation. Brings one out of tier inner thoughts to keep one grounded in the physical world, allowing for reduced stress and quieting harsh inner voices. Purple variations are exceptional at purifying the energy field and working towards spiritual transformation. 
Truly a stone worth having in your collection for the beauty as well as for it's grounding qualities. 
Wishing you a week of inner peace,

Blue lace agate is an agate that is layers of blue chalcedony and white or clear agate with some inclusions of brown sometime occurring within the layers. It has a hardness of 7 on the MOHS scale. The banding can create stripes and or swirling within the stone. It is a soft blue color and is reminiscent of the blue sky and clouds. It can have a light lavender appearance in some lighting. The best quality of Blue lace agate comes from South Africa.
Blue lace agate represents the throat chakra, the element of water and helps with communication, clarity and confidence. Not a protection stone but a healing stone or helper stone. Calms the emotions and helps support confidence. Releases negative habits and helps one communicate one's deepest truth. Helps one to be heard by others, by adding in finding the right words to communicate clearly. 
I love how much it takes me to a time when I would look up at the sky as a child, or with my own child and relaxing in the grass Trying to find the shapes in the clouds and watching them float by. This stone reminds me of calmer days of daydreaming and just simply being.  Blue lace agate is not a bold or brightly colored stone, but that is what gives it it's charm. It is quiet and calm and beautiful.

I hope you enjoyed learning about Blue lace agate. Wishing you a place of calm and confidence.
