Cloisonné is an ancient technique for decorating metalwork objects, but in recent centuries using vitreous enamels, and also inlays of cut gemstones, glass, and even linen. and other cloth materials, has become common place, especially in jewelry beads and pendants.
Prehnite is a phyllosilicate of calcium and aluminium with limited iron substitutes for aluminium in the structure. Prehnite crystallizes in the orthorhombic crystal system, and most oftens forms as stalactitic or botryoidal aggregates, with only just the crests of small crystals showing any faces, which are almost always curved or composite. Very rarely will it form distinct, well individualized crystals showing a square-like cross-section, like those found at the Jeffrey Mine in Asbestos, Quebec, Canada. It is brittle with an uneven fracture and a vitreous to pearly lustre. Prehnites color varies from light green to yellow, but also colorless, blue or white. In April 2000, a rare orange Prehnite was discovered at the famous Kalahari Manganese Fields in South Africa. It is mostly translucent, and rarely transparent. It was the first mineral to be named after a specific person, Colonel Hendrick VonPrehn, and was first described in 1789 for an occurrence in Haslach, Harzburg and Oberstein, Germany. Extensive deposits of gem quality Prehnite occur in the basalt tableland surrounding Wave Hill Station in the central Northern Territory, of Australia.
Amber - The Baltic region is home to the largest known deposit of Amber, called Baltic amber, with about 80% of the world's known amber found there. It dates back some 44 million years ago. It has been estimated that these forests created over 105 tons of amber. Because Baltic amber contains about 8% succinic acid, it is also termed succinite. It was thought since the 1850s that the resin that became Amber was produced by the tree Pinites succinifer, but research in the 1980's came to the conclusion that the resin originates from several species. Numerous extinct genera and species of plants and animals have been discovered and scientifically described from inclusions in Baltic Amber. Do NOT confuse Amber with Copal. Copal is not the fossilized, but rather an immature recent resin. Increasingly, Copal is being offered for sale, via the online auction services, gem shows, and shops, misrepresented as "Amber." The commercial value of Amber is related to its scarcity, age, inclusions of extinct species, and durability. Unfortunately, some dealers are more preoccupied with high economic returns, rather than whether or not their resin is fossil or recent. The age of Copal can vary from 50 years to 1.6 million years in age. It can be considered a semi-fossilized resin or an immature amber.
