Therapeutic Properties of Flower Jasper
Flower Jasper is a multi-colored, gemstone whose colors may range from soft pastel pink, gray, cream and burgundy.
Jaspers bring joy into our lives. It is also a protector for travelers. Jasper is said to vibrate strongly with the 4th Chakra, called the Heart Chakra. Thus this gemstone is useful for bringing emotional balance and to sooth heart-aches. Thus this stone is useful for heart problems. It also eases tension between people and helps you to handle situations calmly.
I am getting into Japser too. I just got a Rainforest Jasper Wand. I love Jasper.
I got 3 Poppy Jaspers too, and Mookaite is a Jasper. Then there is a combo stone called Tiger Iron, which is a combo of Jasper, Hematite and Tiger's Eye that makes me feel great when I touch it.
How is your Flower Jasper working for you?
