Amber is a natural substance known for thousands of years. Besides its beauty and use in jewelry and adornments, amber has been (and still is) used in perfumes and folk remedies (teething, for example). Colors range from pale yellow through deep red and even greens and blues. The warmth of amber has been a fascination of mine and I love wearing it.
Natural amber with inclusion of plants and insects is quite expensive. A less rare form is shown in these two pieces where amber was heated and pressed into a form. Even so, it still retains its beauty and warmth.
