Ever Popular Ever Beautiful Rose Quartz

Of all the variety of minerals and crystals, perhaps the most beloved and widely collected is quartz. Named from the old Saxon word querklufterz meaning ‘cross vein ore’, it is popular with collectors, healers, artists, craftsmen, and people just looking for beautiful jewelry or items to display in their home. Quartz has something for everyone: a startling variety of colors; beautiful geometrically precise crystals; crystals ranging in size from druzy to monumental; strange and fantastical interior minerals such as hematite. Quartz is also the most abundant mineral on our planet.

Pure quartz is a colorless form of silicon dioxide, but there is a wide variety of both colored quartz and minerals that are not commonly understood to be a variety of quartz, such as amethyst, citrine, praseolite, chalcedony, and herkimer diamonds. Many of these varieties derive their color from impurities. Amethyst, for example owes its purple color to a combination of iron impurities trapped in the crystal along with holes in its structure from missing elections. Gray quartz similarly has missing electrons, but instead of iron impurities, it has aluminum impurities. Aside from color, quartz is usually grouped based on the size of the size of individual crystals or grains. If the individual crystal is too small to see using the naked eye, then the crystal is referred to as being cryptocrystalline quartz. If you can use your unaided eye to see the crystal, then it is classified as macrocrystalline quartz.

Rose quartz is a popular macrocrystalline form of quartz best know for its solid masses, beautiful glassy luster and translucent, even, milky pink color. The source of the color is still not well understood. One theory argues that it is due minor impurities such as titanium, manganese or even colloidal gold. The other theory argues that color comes from microscopic mineral fibers of dumortierite inside the rose quartz. Some examples exhibit asterism – a star effect when looking at the mineral from a particular angle when light is shone upon it. In general, rose quartz does not form crystals like you see with other forms of quartz.

Its delicate color has inspired art in other mediums including this glass vase on at the Chrysler Museum, and has its own color listing in the Pantone color library. Man has worked with the material back into antiquity. Beads made of the material have been discovered in the near east. The Chinese, particularly during the Qing dynasty, used the material for carvings. It was crafted in Latin America, and India as well.

Rose quartz was believed by the Romans, Egyptians and Greeks to be a useful talisman, and the Romans carved it into ownership seals. It was known during medieval times as the love stone, and the Chinese valued it’s properties in the practice of Feng Shui. Given the strong and ancient beliefs that the stone had special properties , it is no surprise that a strong literature has arisen around the material in modern times discussing metaphysical, healing, Reiki, or other spiritual properties of the material.

Rose Quartz continues to inspire people, even in modern times. It’s a name given to a character in the Cartoon Network show Steven Universe. In the show, Steven is half-human and half “gem”, a type of ageless alien warrior that project human like forms from the gemstones in their core. Steven inherits his half “gem” lineage from his full-gem mother, Rose Quartz.

Rose quartz is found today in southern Africa (Madagascar, South Africa, and Namibia) as well as Brazil (Bahia and Minas Gerais) and interestingly, South Dakota.

There is a second variety of quartz sometimes grouped under the name rose quartz, but also referred to as pink crystalline quartz or crystalline rose quartz or even just pink quartz. This variety is much rarer, forms beautiful crystals and the best examples hail from the Minas Gerais region of Brazil.

Electrifying Petrified Wood Discovery on the Island of Lesbos, Greece

Petrified Wood Trunk on the Island of Lesbos

The Greek island of Lesbos is notable for it’s Petrifed Wood forest, a protected national monument. The forest is located on the western portion of the island and was formed from the Late Oligocene to Lower–Middle Miocene and consists of  silicified remnants of a sub-tropical forest that going back 20–15 million years ago.

Recent discoveries in the rich Petrified Forest have been electrifying. First was the rare discovery of a spectacular 19.5 meter long log , with accompanying roots, branches, and trees, the only found to date in over 25 years of excavations. Weeks later, the excavators uncovered over 150 more petrified wood logs and petrified wood stumps including conifers, fruit producing trees, sequoia trees, pine, palm, cinnamon and oak trees. The finds were all discovered in the same pit.

The excavation team has been working since 2013 excavating along a 20km stretch of highway and have made 15 major finds, but these all pale to this most recent discovery, which was actually the result of a lucky accident. One the excavators notices a leaf in a stretch of the highway about to get asphalted, and halted the road work.

The park has been designated a UNESCO Global GeoPark. There is an excellent museum well worth visiting. If you visit the park, remember that the removal and transfer of fossilized material is prohibited by law. The forest includes six parks. The fossilized trees include mainly huge sequoias and primitive pine trees in an ecosystem closest to the coniferous forests of North America.

While we haven’t been to Lesbos we do have some of our own spectacular Petrified Wood finds available for sale in our catalog.

Unstable temperature and relative humidity, different rates of expansion and contraction, salt movement, living plant roots and other factors cause cracking in fossil wood. In order to prevent dirt and contemporary vegetation from accumulating into the cracks, and prevent breakages, solutions of especially prepared consolidants are injected in surface cracks.

(2008) ‘Conserving the Lesvos Petrified Forest’, Studies in Conservation 53 (Supplement-1 – Conservation and Access: Contributions to the 2008 IIC Congress), London, p. 141-145] The beautiful rose colours of the silicified fossil wood in this picture are due to the presence of manganese ions.
