via @Charmaine Zoe - Rare cave pearls fill dried-out terrace pools in Hang Son Doong, Vietnam. This unusually large collection of stone spheres formed drip by drip over the centuries as calcite crystals left behind by water, layered themselves around grains of sand, enlarging over time.
Himalayan Soap Nuts - For centuries, soapnuts have been used by people in northern Asia to wash their laundry and finest textiles (e.g. wool, silk, cashmere). They have also been used to make cleaning solutions for washing dishes, floors and hair. Sustainably produced, biodegradable and compostable, soapnut shells are economical and leave your laundry fresh, clean and soft. Soapnuts are gentle on skin and clothes and suitable for sensitive skin, allergy and eczema sufferers.
