All Jewelry. Our Creative Director. Since , under Helen's creative direction, Reflective Jewelry has crafted jewelry that brings benefit and beauty to the world. Ethically Sourced Gemstones. Our Ethical Diamond Sources. Let's create a handmade, custom ring together! Browse our Diamond databases, or call us at with your ideas.
Diamond Education. Our Tradition as Makers. The energy of the artisan, the love of craft and long-honed skill, is transferred into the piece itself, making it more beautiful, enduring and talismanic.
Custom Designs. Why Reflective Jewelry. My partner and I both had custom engagement rings designed here, and they were absolutely perfect! The materials are top-quality and ethically sourced, and our rings are everything we dreamed of! The Ethical Jewelry Manifesto. Martin Luther King Jr. Educational Videos. Our Activist Company.
See the Mine. Our Fairtrade Gold comes from Macdesa a small mining operation in Peru. Fairtrade Gold. Overview of Total Materia database 3 rd and 4 th November Overview of Total Materia database 12 th and 13 th January Total Materia has allowed us to solve in a definite way all problems we had for the search of alternate materials in foreign countries. Thanks to Total Materia we have issued real "international" specs for purchase of steels in foreign countries.
Our mission is simple; to make Total Materia the one-stop place and first choice of engineers world wide. The metal gold is extremely malleable. Gold is also ductile and one ounce can be drawn into 80 km of thin gold wire 5 microns diameter to make electrical contacts and bonding wire. Gold has a Young's modulus of 79 GPa which is very similar to silver, but significantly lower than iron or steel. The purity or fineness of gold in the jewelry is indicated by its karat number.
Gold, symbol Au has an atomic number of 79 i. The atomic mass of the gold atom is Interestingly this is smaller than would be predicted by theory. The arrangement of outer electrons around the gold nucleus is related to gold's characteristic yellow color. The color of a metal is based on transitions of electrons between energy bands. The conditions for the intense absorption of light at the wavelengths necessary to produce the typical gold color are fulfilled by a transition from the d band to unoccupied positions in the conduction band.
Whilst the number of protons in a gold nucleus is fixed at 79, the number of neutrons can vary from one atom to another giving a number of isotopes of gold. However, there is only one stable non-radioactive isotope accounting for all naturally found gold.
Gold is also ductile and one ounce can be drawn into 80 km 50 miles of thin gold wire 5 microns diameter to make electrical contacts and bonding wire. The Young's modulus of elasticity of a material is related to rigidity or stiffness and is defined as the ratio between the stress applied and the elastic strain it produces. Proof gold is even finer, with over Colored gold alloys are just as "real" as their golden colored counterparts. Pure gold is generally too soft to be used for jewelry, so other metals are nearly always added to it, no matter which color of gold is being prepped for jewelry making.
The designations 18 kt, 14 kt, or 10 kt indicate how much pure gold is present in the mix. The K stands for karat, the system used to state how much pure gold is found in an item: 24 kt gold is pure gold. Even 18 kt gold, with its 6 parts of another metal, gives jewelers the opportunity to play around with color.
In Table 1 are shown chemical compositions of different colored golds. Monel metal, 67 percent nickel and the balance essentially copper , is stronger than nickel and has broad corrosion-resisting applications. Gold Au in its bulk form, like the metal in a wedding ring, is not considered a magnetic material. In its purest form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal.
Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. The most common gold purity levels are 10k karat , 14k, 18k and 24k.
Each level of gold purity offers its own range of advantages and disadvantages, from hardness and durability to the risk of certain levels of gold purity contributing to skin irritation. Wearing solid gold jewelry, white gold or yellow gold, in the shower will not harm the metal itself, however it can reduce the shine therefore it is not recommended. Showering with gold plated jewelry can eventually cause the gold layer to wear off completely, therefore you should definitely refrain from doing so.
Gold is NOT attracted to a magnet. One way of telling if your jewelry is actually gold is by using a magnet. If your gold is magnetic , then there is iron or nickel inside of it.
If it is pure 10k gold , it will never fade. So even though your necklace is 10k , it is still mixed with other metals likely silver and bronze to add weight. So, since 10K gold is harder , jewelry made with it is more durable and less prone to bending than 14K gold.
Rose gold is made of pure gold mixed with copper and silver alloys. Rose gold is real but it's not made entirely of gold. The more copper used, the redder the gold appears. So, which one is the best? Its current popularity in jewellery is due to the comeback of colour in fashion at the start of the 21st century — rose gold complements the frilly shades and neutral colours. Additionally, rose gold jewellery is more rare, says Duvall O'Steen, the director of jewellery promotion for the World Gold Council.
