Ivory is a hard, white material from the tusks (traditionally elephant’s) and teeth of animals, that can be used in art or manufacturing. It consists mainly of dentine (inorganic formula Ca10(PO4)6(CO3)·H2O)), one of the physical structures of teeth and tusks. The chemical structure of the teeth and tusks of mammals is the same, regardless of the species of origin. The trade in certain teeth and tusks other than elephant is well established and widespread; therefore, “ivory” can correctly be used to describe any mammalian teeth or tusks of commercial interest which are large enough to be carved or scrimshawed.[1] It has been valued since ancient times for making a range of items, from ivory carvings to false teeth, fans, dominoes and joint tubes. Elephant ivory is the most important source, but ivory from mammoth, walrus, hippopotamus, sperm whale, killer whale, narwhal and wart hog are used as well. Elk also have two ivory teeth, which are believed to be the remnants of tusks from their ancestors. The national and international trade in ivory of threatened species such as African and Asian elephants is illegal. The word ivory ultimately derives from the ancient Egyptian âb, âbu (“elephant”), through the Latin ebor- or ebur.

Silver is a white metallic element, harder than gold, softer than copper and second only to gold in malleability and ductility. Represented on the Periodic Table of the Elements by the symbol Ag, silver is an excellent conductor of heat and electricity. Silver is considered one of the noble metals because of it is excellent resistance to oxidation. Historically, silver has played a prominent role in the production of jewelry an objets d’art and is usually alloyed with another metal to harden it enough to maintain the desired shape and details imparted to it.

Authenticity, antiquity, decorative periods, vintages and or circa dating are determined to the best of our ability based on materials incorporated, methods of manufacture, design, hallmarks and signatures, lapidary techniques, technological developments and consultation of our extensive reference library and materials. Dating and period attributions are not an exact science as decorative periods frequently overlap and borrow influences from one another.
​ Some of our pieces are mounted in a way that makes it difficult to determine a precise stone’s grading. Diamonds and colored gemstones that cannot be removed from their vintage settings without harm to the piece are evaluated in their mountings using industry-standard measurements and formulas. Jewelry descriptions and all carat weights stated represent approximates. Mounted stone(s) is/are graded only insofar as mounting permits observation. All diamonds shown on our website are natural, untreated diamonds.
Most colored gemstones (i.e. rubies, sapphires, and emeralds) are commonly treated to enhance colour or clarity. This has not been researched for this specific item.
We cannot guarantee that the color you see matches the item color, as the display of color depends, in part, upon the type of computer monitor used to observe the image.
