Nassarius whelks in the aquarium

Other than the algivororous snail species, such as ceriths and trochoids, probably the most commonly traded gastropods are the nassas, Nassarius sp., a genus of dog whelks. Especially in the USA, it is the Caribbean Nassarius vibex that is most widely sold in aquarium stores, though sadly, coldwater species are mistraded either explicitly or implicitly, as N. vibex itself, or as sharing a similar tropical habit. Other species from locations such as Tonga are regularly encountered, although a formal species identification, is rarely if ever attempted. If a whelk is traded as 'super nassarius' or similar, these nassas can be expected to outsize the diminutive N. vibex, which grows to only 2 centimeters, or 3/4 of an inch, at the most.

Nassas are burrowing snails requiring a fine substrate to dig themselves through. Also as members of the whelks or buccinoids, they have a carnivorous nature, although their utilitarian appeal to aquarists, is that unlike most whelks, nassa feeding behavior is stimulated by the decomposition of animal tissues. They are thus obligate scavengers, consuming the leftovers of the meaty foods, that are relished by most reef fish. Seemingly lacking a raptorial nature, or inclination to rasp sessile animals, nassas are thus regarded as reef safe neogastropods.

Paleolithic eyed needles and the evolution of dress (Science Advances 28 June 2024)

This article uses the spread of bone awls and needles to trace the evolution of clothing from simple, minimally protective coverings to finely tailored, insulating garments across the geography of the Last Glacial Maximum. Not surprisingly, needle use is associated with cold climates and the need for warm, fitted clothing. But the wide variation in needle size, including very small ones for fine, delicate work, along with frequent discovery of shell and bone beads showing use wear consistent with rubbing against clothing, shows the evolution of clothing into dress. Bodily adornment transitioned to clothing to mark identity and status.

Timeless Elegance: The Allure and Craftsmanship of Exquisite Jewelry

In a world where trends come and go, one element of style remains perpetually captivating: exquisite jewelry. These dazzling pieces are more than mere accessories; they are works of art that tell stories, evoke emotions, and serve as symbols of love, power, and status. The allure of fine jewelry transcends time and culture, capturing the hearts and imaginations of people across the globe. From ancient civilizations to modern fashion runways, jewelry has played a pivotal role in human history, reflecting the artistry and craftsmanship of its makers.

The History and Evolution of Jewelry

Jewelry has been an integral part of human adornment for thousands of years. The earliest known jewelry dates back to around 100,000 years ago, with the discovery of beads made from Nassarius shells. Ancient civilizations such as the Egyptians, Greeks, and Romans adorned themselves with intricate pieces made from gold, silver, and precious gemstones. Each culture had its own unique styles and techniques, often using jewelry to signify status, religious beliefs, and personal identity.

The Egyptians, for example, were known for their elaborate necklaces, bracelets, and rings made from gold and adorned with colorful gemstones like turquoise, lapis lazuli, and carnelian. These pieces were not only decorative but also believed to have protective and magical properties. Similarly, the Greeks and Romans used jewelry to showcase their wealth and social standing, often incorporating mythological motifs and intricate designs.

During the Middle Ages, jewelry became more symbolic, with religious themes dominating the designs. The Renaissance period marked a revival of classical art and culture, leading to an explosion of creativity and innovation in jewelry making. This era saw the introduction of new techniques such as enamel work and the use of gemstones to create intricate and realistic floral designs.

The 19th and 20th centuries brought about significant advancements in jewelry design and manufacturing. The Victorian era, named after Queen Victoria, was characterized by sentimental and romantic pieces, often featuring motifs like hearts, flowers, and lockets. The Art Nouveau movement, which emerged in the late 19th century, embraced flowing lines, natural forms, and a sense of organic beauty. This was followed by the Art Deco period, which introduced bold geometric shapes, vibrant colors, and a sense of modernity that continues to influence contemporary jewelry design.

The Art of Craftsmanship

The creation of exquisite jewelry is a meticulous process that requires a high level of skill, precision, and artistry. Each piece begins with a concept or design, which is often inspired by nature, history, or personal experiences. Jewelry designers use a combination of traditional techniques and modern technology to bring their visions to life.

One of the most important aspects of jewelry making is the selection of materials. Precious metals such as gold, platinum, and silver are commonly used as the foundation for fine jewelry. These metals are prized for their durability, malleability, and timeless appeal. Gemstones, on the other hand, add color, brilliance, and value to a piece. Diamonds, sapphires, rubies, and emeralds are some of the most sought-after gemstones, each with its own unique characteristics and allure.

Once the materials are selected, the process of creating a piece of jewelry involves several steps, including:

Designing: The designer sketches the initial concept, taking into consideration the aesthetics, functionality, and wearability of the piece. This stage often involves collaboration with the client or other artisans to refine the design and ensure it meets their vision.

Wax Modeling: A wax model of the piece is created to serve as a prototype. This model allows the designer to visualize the final product and make any necessary adjustments before moving forward.

Casting: The wax model is encased in a plaster mold and heated until the wax melts away, leaving a cavity in the shape of the jewelry. Molten metal is then poured into the mold to create the basic structure of the piece.

Setting Gemstones: Skilled gem setters carefully place each gemstone into its designated setting. This requires precision and expertise to ensure the stones are securely held in place while maximizing their brilliance and beauty.

Polishing and Finishing: The final steps involve polishing the metal to a high shine and adding any additional details, such as engravings or enamel work. The piece is then inspected for quality and perfection before being presented to the client.

The Emotional and Cultural Significance of Jewelry

Exquisite jewelry holds a special place in the hearts of people around the world. It is often associated with significant life events, such as engagements, weddings, anniversaries, and graduations. These pieces serve as tangible reminders of cherished moments and milestones, passed down through generations as family heirlooms.

In addition to its personal significance, jewelry also plays a crucial role in cultural and religious traditions. In many cultures, jewelry is used to symbolize wealth, status, and social identity. For example, in India, elaborate gold jewelry is an essential part of bridal attire, representing prosperity and marital bliss. In West Africa, traditional beadwork and gold jewelry are worn during ceremonies and celebrations to honor ancestors and signify cultural heritage.

Jewelry also serves as a form of self-expression, allowing individuals to showcase their unique style and personality. Whether it's a statement necklace, a pair of elegant earrings, or a timeless bracelet, each piece of jewelry tells a story and reflects the wearer's identity and taste.

Mystical Beads and Stones

Getting information about the power of opal stones and beads has never been easier when this article was written. Read on to know more--

You go to a small, hard-to-find store. Once there, the owner will ask you to write your name and address - he won't deliver anything to you, but to decide which stone beads are "right" for you. Strings of specially selected beads are created here in Okinawa by reinosha or shamans. These rubber band bracelets with beads of aventurine, turquoise, topaz, rose quartz and many other minerals and materials are meant to change your mood, or at least bring you luck.

Mystical Beads and Stones

Functionally, the opal necklace can be useful as an amulet or talisman. The terms are often confused. The amulet repels danger, misfortune or evil. A talisman has the power to attract something beneficial on behalf of its wearer, bestow virtues or blessings.

WIKIPEDIA SAYS- A pair of beads made from Nassarius shells, which are approximately 100,000 years old, are believed to be the first known examples of jewelry.

Both stones and beads have a long history in magic and belief.

Since the Middle Ages, the knowledge of the healing or protective properties of stones has been considered an essential factor in alchemical medicine and occultism, three branches of knowledge which at that time were almost one and together formed the whole of modern science.

The following list contains bead materials and their associations.

Moonstone: Luck for lovers

Opal: Gives hope

Carnelian: PMS relief

Wood: Simplicity

Topaz: Power over wild animals

Eye of the Tiger: Courage

Apatite - Increases creativity

Citrine - Increases self-confidence

Garnet - Generates health

Labradorite - supports digestion and metabolism

Pearl - means faith

Peridot - Overcomes anger and jealousy

Quartz (clear) – Stimulates brain function

Based on the theory that stones, especially crystals, vibrate at a certain frequency; the energy of the stone can be used to balance the electromagnetic waves of the body. Others believe that wearing certain stones can affect your chakras or energy centers.

One legendary stone was known as the Black Prince Ruby. [Edward, Prince of Wales (1330-1376) was called the Black Prince because he wore black armour.] The ruby ​​was so called because it was a large red stone. Edward was sixteen when his heroism during the Battle of Crecy won him praise; a later battle earned him a stone, already considered a powerful amulet. Henry V. wore it in his helmet at Agincourt; he was credited with saving his life when the helmet was split by a battle axe. Richard III wore it at Bosworth. It is still the most famous stone among the British Crown Jewels.

Beads also have a rich history of spirituality and ritual use that stems from prayer beads and belief in the healing powers of gemstones. For thousands of years, man has decorated himself with beads and assisted in spiritual and ritual ceremonies. The root word for bead, bede means to pray, and the earliest use of prayer beads is traced to the Hindus. Stringing the beads together allowed the user to keep track of the number of repeated prayers.

According to A History of Prayer Beads by Marcia Jo Mycko, rosary beads were used before the 12th century for talismanic purposes (as a superstitious object to ward off illness or bring good luck). For example, coral was thought to purify the blood and prevent disease in children.

Once the Church decided that rosaries were more suitable for counting devotions than for protection against talismans, persons with the cloth were forbidden to wear "pagan" rosaries made of coral, quartz or amber.

DID YOU KNOW? In the Middle Ages, opal was considered a stone that could provide great luck, as it was believed to have all the virtues of every gemstone whose color was represented in the opal color spectrum.

Whether you believe in the power of stones or beads or not, all jewelry has some magic. Perhaps you inherited a ring that was actually considered a lucky piece worn daily by your great-grandparents? Or a gem in an unusual setting? Or a small string of beads whose original meaning as a christening gift has been largely forgotten? So rather than traveling to Okinawa for a special shaman bracelet, maybe you should just rummage through your jewelry box and get some charms.

Her aggression is really interesting because she is literally the most peaceful creature with literally all of her tankmates. The emerald crab (Posy) can hang out by Socks' cave as can the pom pom crab (Boondoggle), she will dine with the big nassarius snails right outside her home, the conchs can literally just go inside her cave and snoof around. She hasn't even harmed a single coral or the feather duster that lives next door. Shrimp a quarter her size in the same genus though? Fight on sight. I knew fire shrimp could be aggressive with conspecifics and potentially skunk cleaner shrimp but didn't think it would be an issue with tiny peppermint shrimp that don't really share the same niche. Shrimp on shrimp violence.

At least today it seems like she only chases them if they're right near her cave rather than charging them because they're hanging out at the other side of the tank. She also seems to not be going out looking for them any more. If she continues to be too aggressive though I might need to return them. So far she seems mostly interested in running them off her turf rather than murdering them but I'm worried about what would happen if she backed one into a corner where it physically could not escape and her little shrimp brain processed that as "You still ain't leaving my property huh? Guess you'll have to leave it in pieces."

I bought two small peppermint shrimp yesterday and these little guys are so fucking cute. Socks kinda hates them though, but she seems to slowly be getting less aggressive with them

This is my gorgeous nassarius, Shiny Phanpy. She’s pink because her shell is totally overgrown with coralline. But her best accessories are her two little teensy bulbs of some kind of macro algae that grow at the top of her shell. They look like a little green bow or pigtails!

She’s standing waving by the also-pink-and-green coralline covered liverock to match because she’s a diva.

I know they won't last long, but my nassarius laid eggs! That's a happy snail.

My first reef tank! I added the animals yesterday and so far everyone is doing well. The cycling process was accelerated with seachem stabilizer beforehand. The fish is an azure damselfish and the inverts are a camel shrimp, a dwarf zebra hermit crab, and a nassarius snail. I also have fern feather macroalgae planted and ordered some red gracilaria. No corals yet. When I get the time to go to Absolutely Fish I'm going to get a pulsing xenia at the very least, and maybe a Kenya tree. I can't get any leather or mushroom corals because the camel shrimp might eat them.
