Step 3: Position the Crystals for Success. Focus Stone. The focus stone is the center stone of the grid. While it's common to see lofty pyramids and towers, we chose a 3-inch crystal quartz sphere. Crystal quartz can be programmed with any intention or positive affirmation, and the round shape encourages a gentle flow of energy.

Find a wand made from selenite, quartz, or copper. Or, if you're limited on tools, use your pointer finger or the palm chakra to energize the grid. Rest the wand above the focus stone. Let it hover a couple of inches over the center crystal before moving to …

Selenite has been a top favourite for many crystal lovers dating back to the Ancient Greeks who named the translucent crystal Selenite which means "moon" in Greek. They even constructed windows out of Selenite to allow light into darker rooms. Selenite is commonly found in the deep caves of Mexico, Morocco and Madagascar and the raw crystal formations …

We studied selenate and selenite sorption by amorphous Fe oxide [am-Fe(OH) 3] and goethite (α-FeOOH) as a function of time (25 min–96 h), pH (3–12), ionic strength (0.01–1.0 M NaCl), and total Se concentration (0.0001–1.0 M).We examined sorbed selenate and selenite by in situ attenuated total reflectance Fourier transform infrared (ATR–FTIR) spectroscopy, …
