Metals
Brass: Brass is an alloy mixture of copper and zinc. It is known for bringing out one’s natural inner truth and good. The saying "getting down to brass tacks" tells of clearing the old and stepping into the new, natural truth.
Copper: Is one of the most conductive metals. This metal sits on the periodic table at number 29 with the symbol CU. Since it is one of the most conductive metals, it clears one’s energy and puts you in the flow to one’s psychic ability. Because of these elements, we used copper for our sacred geometry sculptures.
Gold: Gold has been said to be the sweat of the sun. Worshiped for its brilliance and highly valued since before recorded history. It has an electrical conductivity and provides warm sun-energy to the heart chakra and is known for its healing properties. This precious metal sits on the periodic table at number 79 with the symbol AU. Pure gold (24 karat) is very soft but we use 18k for all our pieces and 22k gold plating for the gold vermeil jewelry. Pure gold is usually alloyed with a mixture of other metals to give it strength, durability, and add to its golden color.
Platinum: Platinum has long been associated with rarity, endurance, and prestige. It is an enduring metal, valued for its natural white luster and exceptional durability. Used since ancient times and prized in fine jewelry, it is highly resistant to tarnish and corrosion and offers stable electrical conductivity. Platinum appears on the periodic table as element 78 with the symbol Pt. It is typically used in high purity, most commonly 950 platinum (95% pure), and is alloyed with metals like iridium or ruthenium to enhance strength while maintaining its natural silvery-white color.
Sterling Silver: Silver has been said to be the tears of the moon, bringing clarity and healing as it reflects the soul. We use sterling silver, which is an alloy of 92.5% silver mass and 7.5% of other metals. The 7.5% aids in the strength and durability of the metal when used in jewelry. Silver sits on the periodic table at number 47 with the symbol Ag. It is a natural antimicrobial, and when ingested can prevent illness. In ancient times, goblets were made in silver for just these reasons. In ancient times, it would prevent illness. can be woven into clothes to prevent bacterial growth, or even ingested as a colloid to treat and prevent illness.
Caratage is the measurement of the purity of gold alloyed with other metals. 24 carat is pure gold with no other metals. We use 18k gold in all our jewelry, which is 75% gold 25% other metals. The other metal is usually copper or silver, which at different amounts, can give you a white gold or a yellow gold, depending on the amount.
Caring for your gold and silver
Each piece of jewelry you are about to purchase will arrive in a custom pouch to preserve the integrity of your investment. We have taken into consideration oxidation and have placed each piece on a padded bed with ribbon hooks and inserted this into a sealed bag, which includes a tarnish-resistant tab. This bag is then enfolded into an envelope pouch with our custom logo ribbon tie. This custom jewelry bag is our gift to you so you may store your jewelry with the utmost care.
