Various industrial sectors have formally turned to Green Development, practicing eco-design with the goal of saving the environment. Such trend can also be applied to jewelry design and production. Jewelry, which emerged with the birth of humankind, has been a contributing factor to environmental pollution and depletion of resources due to mass production and reckless consuming patterns of the 20th century. With the arrival of the World economic crises, however, the consumption of jewelry has dropped and now the industry desperately needs a boost for revival. In this paper, we propose a way to recycle waste materials and turn them into a new kind of jewelry. We introduce various junk materials that can be reused, and how to reuse them. The new type of jewelry we aim for is environment-friendly, low-cost, and unique as opposed to identical mass production of the past. The eco-design product will likely add new value to jewelry industry. The product targets sophisticated modern consumers with conscientious, environmentally aware consuming patterns. To fulfill the needs of these consumers, we propose methods of upcycling from junk to jewelry, by combining precious stones with waste materials.

Except for traditional industrial art and history of design development, Korea jewelry industry before 1980's, had little meaning in the aspect of marketing and business. Domestic jewelry market which have changed from the value of goods to value of ornaments, faced important transition point for jewelry industry by the chance of in Asian Game held in 1986, and money of overseas traveler after 1980s. The rapidly-grown Jewelry field by the introduction of detail casting method to make it possible mass-production of the products before 1990's, began to change into new system, with introducing CAD/CAM after 1990's. Jewelry industry has changed from manual work called handmade to the detail casting industry based on master for mass-production. For this, the development of master, with the design development, have been suggested as important task to jewelry industry firms, and by the introduction of CAD/CAM, the diversification of design and master development has been made up. In this study, we would try to find out current status of domestic jewelry field and to understand CAD/CAM, and advantage of CAD/CAM, and through this, suggest good solution to precipitate domestic jewelry market.

The master pattern manufacturing process is one of the most important processes in jewelry industry because the process takes 20% of total jewelry manufacturing costs. The previous jewelry manufacturing process has many steps of "rough design${\leftrightarro}$ detailed drawing${\leftrightarro}$ wax pattern manufacturing ${\leftrightarro}$ lime soda flask mold manufacturing ${\leftrightarro}$ silver master pattern manufacturing ${\leftrightarro}$ mass production of wax pattern ${\leftrightarro}$ investment casting process ${\leftrightarro}$ final jewelry product." A novel process that reduces processing steps by using a rapid prototyping system (RP) has been suggested. The process is "3D CAD design ${\leftrightarro}$ DuraForm mold manufacturing by RP ${\leftrightarro}$ manufacturing master pattern by low melting alloy ${\leftrightarro}$ mass production of wax pattern ${\leftrightarro}$ investment casting process${\leftrightarro}$ final jewelry product." Molds are made with DuraForm powder, of which melting temperature is 19$0^{\circ}C$, by a selective laster sintering type RP. An alloy of Pb-Sn-Bi-Cd, of which melting temperature is $70^{\circ}C$, is casted in the DuraForm molds. Spheres and rings of diameter 20 mm are made by this process. The dimension deformation rate is less than 2%, and the post processing of the castings is convenient. The casting made by the suggested process can be used as a master pattern of jewelry products.of jewelry products.

There are many restrictions in conventional ways of Jewelry mass production which are Mokume Gane, Inlaid Technology based on a joining work of dissimilar metals. To overcome this, Multi-Casting using both Jewelry-Casting and CAD/CAM has presented. In experiment on Muti-Casting, second original sample which was produced by CAD/CAM is 5 % smaller than first one. The first and second castings are brass and silver, respectively. When making second sample, the temperature of flask was about $150{\sim}200^{\circ}C$ higher than the standard temperature of flask when making castings. Through the Multi-Casting, it was found that there was no trouble making dissimilar metals Jewelry which can be mass produced.

To satisfy consumers' desire to enjoy their own individuality and cultural trends, the discovery of various materials and the expression of materials embodying their characteristics are increasingly important in the fashion jewelry industry. This study examines, paper mulberry fiber, a raw material of hanji that has been excavated as a new material for fashion jewelry, is durable as wall as, soft and easy to form, has a unique texture along with, excellent aesthetic quality, and expresses various colors, thereby differentiating itself from traditional fashion jewelry materials. The material itself also has symbolic significance as an approach to discovering new sustainable materials for fashion jewelry to ensure increased specificity of the product based on the premise of freedom of expression. The weight and optimal drying time of chicken fiber were derived for the study of fashion jewelry expression using the characteristics of paper mulberry fiber. The techniques of casting, deflection, packing and winding (winding beads with fibers and straps) were derived and four brooches were produced in total. This study is meaningful for the future of, the fashion jewelry industry as it presents the uses of new materials such as paper mulberry fiber to induce multidisciplinary consumption and to suggest a direction for the creation of new value-added products. Further, in order to expand the realm of fashion jewelry industry with our own competitive products that have secured our cultural identity and uniqueness in the global market, there must be continued follow-up research on mass production methods for industrialization.

Since the Industrial Revolution, which made the mass production and mass distribution of standardized goods possible, machine-made (manufactured) products have accounted for the majority of the market. However, in recent years, the phenomenon of purchasing even more expensive handmade products has become a noticeable trend as consumers have started to acknowledge the value of handmade products, such as the craftsman's commitment, belief in their quality and scarcity, and the sense of self-esteem from having them,. Consumer interest in these handmade products has shown explosive growth and has been coupled with the recent development of three-dimensional (3D) printing technologies. Etsy.com is the world's largest online handmade platform. It is no different from any other online platform; it provides an online market where buyers and sellers virtually meet to share information and transact business. However, Etsy.com is different in that shops within this platform only deal with handmade products in a variety of categories, ranging from jewelry to toys. Since its establishment in 2005, despite being limited to handmade products, Etsy.com has enjoyed rapid growth in membership, transaction volume, and revenue. Most recently in April 2015, it raised funds through an initial public offering (IPO) of more than 1.8 billion USD, which demonstrates the huge potential of online handmade platforms. After the success of Etsy.com, various types of online handmade platforms such as Handmade at Amazon, ArtFire, DaWanda, and Craft is ART have emerged and are now competing with each other, at the same time, which has increased the size of the market. According to Deloitte's 2015 holiday survey on which types of gifts the respondents plan to buy during the holiday season, about 16% of U.S. consumers chose "homemade or craft items (e.g., Etsy purchase)," which was the same rate as those for the computer game and shoes categories. This indicates that consumer interests in online handmade platforms will continue to rise in the future. However, this high interest in the market for handmade products and their platforms has not yet led to academic research. Most extant studies have only focused on machine-made products and intelligent services for them. This indicates a lack of studies on handmade products and their intelligent services on virtual platforms. Therefore, this study used signaling theory and prior research on the effects of sellers' characteristics on their performance (e.g., total sales and price premiums) in the buyer-seller relationship to identify the key influencing e-Image factors (e.g., reputation, size, information sharing, and length of relationship). Then, their impacts on the performance of shops within the online handmade platform were empirically examined; the dataset was collected from Etsy.com through the application of web harvesting technology. The results from the structural equation modeling revealed that the reputation, size, and information sharing have significant effects on the total sales, while the reputation and length of relationship influence price premiums. This study extended the online platform research into online handmade platform research by identifying key influencing e-Image factors on within-platform shop's total sales and price premiums based on signaling theory and then performed a statistical investigation. These findings are expected to be a stepping stone for future studies on intelligent online handmade services as well as handmade products themselves. Furthermore, the findings of the study provide online handmade platform operators with practical guidelines on how to implement intelligent online handmade services. They should also help shop managers build their marketing strategies in a more specific and effective manner by suggesting key influencing e-Image factors. The results of this study should contribute to the vitalization of intelligent online handmade services by providing clues on how to maximize within-platform shops' total sales and price premiums.
