On a recent gemstone sourcing shopping trip, I found this amazing Herkimer Diamond at one of my favorite vendors. After doing some research on the gemstone and wearing it a few days, the stone's healing abilities really came through to me. Its called the Attunement Stone and because it's a double terminated quartz it's master healing properties are very strong.
Unusually transparent with a brilliant sparkle, they manifest pure, solid Light and are powerful amplifiers of spiritual energy. As perfect conduits of the universal Life Force, they are exceptional healing crystals, and are used in meditations, dream and vision work, and advanced spiritualization applications.

Herkimer Diamonds are ascension stones, and they will take you to the highest spiritual vibration possible while still being in your physical body. These crystals have powerful metaphysical properties and are strong stones to aid astral travel, as they help to connect the astral plane to the physical plane. They are beautiful and powerful high vibration crystals, that boost clairvoyant and clairaudient abilities. They act as powerful amplifiers when you are using them with a small stone.
