Pearls : The Most Common Pearl Makers Are Oysters

Jade Stones “nephrite” are a mineral composed of magnesium, iron, and silicate of calcium. Usually, they are formed through extreme heat and pressure known as metamorphism. Surprisingly, it can be found on every continent in the world, including countries like New Zealand, Brazil, China (Sinkiang), Canada, Zimbabwe, and the United State. It can be found in serpentine rock, by mining, alongside riverbanks, and seashores. Due to its composition these stones are shaped and polished before it is used in massage ("Nephrite Jade Gemstone Information", 2014).

Taking about a week to fully mature into an adult and living for several months, the shrimp do have a surprisingly long life cycle being also able to reproduce up to 300 cysts every 4 days in the right conditions. Other variables such as salinity, temperature, light, pH levels, water levels and predatory presence play a large role in the hatching rate of the crustacean. The brine shrimp are an extremely versatile micro-crustacean as they can survive up to 10x salt concentration of ordinary sea water (Eol.org, 2016) and are able to protect themselves during drought or when conditions are not ideal for survival. This is called highly resistant encysted gastrula embryo (cyst) that is easily able to hatch under conditions that can be replicated at home.

The process of producing the diamonds so they could be sold on the market involved many steps which were illustrated in the movie, Blood Diamond. Smugglers like Archer would supply the RUF with guns. The guns would be used by the RUF to intimidate the people of Sierra Leone into working as laborers for them, we see this with Solomon and his son. These men would be forced to dig in the water mines for hours a day searching for diamonds of all sizes. Then the diamonds are mixed with other diamonds all around the world, mixing the illegal ones with the legal ones; this was explained in the movie by Archer to Maggie. When the diamonds are mixed in with the others, no one can determine for certainty where each originated from. It is then distributed to nations where they are made into necklaces and bracelets, and no questions are asked.

The purpose of this lab was to answer the question, “Of the saline solutions of 0%, 0.5%, 1%, 1.5%, and 2% sodium chloride (NaCl), which solution will yield the highest hatching viability for the brine shrimp?” The hypothesis was that the saline solution most precise to the concentration of NaCl in seawater, which is approximately 3.5%, will yield the highest hatching viability. Therefore, the 2% NaCl solution will yield the highest hatching viability.

Some examples of rocks and minerals found in Louisiana are Agate, Louisiana Opal, Cabochon, and Petrified Wood. Agate is a mineral found in Louisiana. Agate is the official state mineral. This mineral is often found in the gravel. Agate can be classified as a mineral and a rock. It is formed by precipitation of silica-rich solution chemicals in rock cavities. Agate is a classified as a microcrystalline assortment of Silica and Chalcedony, and it is characterized by its fine grains and color brightness. In Vernon Parrish, Louisiana the Louisiana Opal can be found. Small amounts of this has been traced from mining in the Catahoula Formation. Louisiana Opal is a mixture of sandstone and cement clear precious opal. In 2011, Cabochon became the state’s official gemstone. The gemstone is derived from Crassotrea Virginica Mollusk. The most commonly known gem in Louisiana is the Petrified-Wood. Found in the Catahoula Formation, this gem is a sedimentary rock formed in the plains and swamps in the Oligocene Gulf

Close to 49% of diamonds are coming from Central and Southern Africa. Also sources of the mineral have been discovered in Canada, India, Russia, Brazil, and Australia. They are mined from kimberlitic and lamproite volcanic

Their shells are fluted, irregular, chalky-white or gray, new growths this often colored purple, and can be distorted to conform to the shape of the object to which the oysters is attached. Oysters are often found in groups attached to one another or to an object such as a rock or a shell. Oysters have uneven valves, which is also known as the shells. The lower shell is cupped and often attached to a hard object. The upper shell is flattened and smaller than the lower shell. Spawning during the hot summer months temporarily reduces the quality of oysters, making them less

Two of the most famous styles of jewelry produced were the Squash blossom necklace and the Navajo turquoise inlay rings. The Squash blossom was made from silver and turquoise with the Naja symbol on it. Some of the machinery they used that were given to them by traders. Before, they had to use rough tools for manufacturing jewelry because at the time they did not trade. A couple of the tools that they used were hammers and

As per J. Willard Hershey in "The Book of Diamonds," precious stones were initially found in Arkansas in 1906. The state is one of the most elevated designer of the stones in the United States; somewhere around 1972 and 2005, 25,369 jewels were mined in the state, as per the official state website.Often called "Arkansas jewels," quartz gems are minerals found in Arkansas. Quartz precious stone was announced the state mineral in 1967.

Types of Jewelry Diadems Laurel leaves, flowers and small fruits of great finesse were used in these diadems. Necklace Women of this civilization like to wear them in numbers and with different lengths.

October 3rd-4th was Oyster Fest weekend. It was in Shelton WA. On the 3rd it stared at 10am-6pm and on the 4th 10am- 5pm. The ticket price to get in was $5 and food prices were a range of $3-$10. There was live country music on both of the stages. One booth had a mine golf game. Plus there was a train that took kids 3-7 around the park.

Maine’s land is 80 percent of forest. Maine has many different types of trees. They are everywhere. The trees are maple, birch, spruce, and pine. Farmers would use the oyster shells for fertilizer, they

Soapstone is a soft material that is easy to be carved. However the stone breaks very easily due to this soft nature, This week we are learning how to carve soapstone pendants and jewelry, and we have already discovered several problems in the carving process. Thus it is so fascinating to see what the Inuit culture has done with this type of stone.

The main give away that a pacific oyster has contracted POMS is that it will die 8-10 days of infection. (4). However there also visible symptoms of POMS including gaping in adults, the digestive glad will appear pale in spat and older oysters and the termination of feeding and swimming by larvae, suggesting internal tears (3). In addition, severe swelling also occurs and it ranges from being mild and contained through to being severe and widespread. (3)

Now, an ordinary person, who has no knowledge of precious gems, might not be able to tell the difference between the two but a jeweler, with his knowledge and proper apparatus, can easily tell the difference. Hence, Pir Sadarddin asks in one of Ginans:
