Vintage

Vintage jewelry is jewelry which is not old enough to be considered antique (100 years old or older), yet not modern or contemporary, it includes jewelry that were constructed and worn during the Art Deco, Retro, and Mid-Century periods.

Rose Cut Diamond

The rose cut features a flat bottom with a dome-shaped crown, rising to a single apex. With anywhere from 3 to 24 facets, a rose cut diamond resembles the shape of a rose bud. The rose cut dates to the 1500s and remained common during the Georgian and Victorian eras.

Lolite (water sapphire)

Iolite is the name used for gem quality specimens of the mineral cordierite. Gem iolite is typically light to dark blue or violet blue in color, with excellent transparency and strong pleochroism. It is quite a hard material, about the same as tourmaline, so it is suitable for all kinds of jewelry. Iolite is also a fairly inexpensive stone, especially when compared to other violet-blue gems such as tanzanite. Cordierite is a magnesium iron aluminum cyclosilicate that was first discovered in 1813 and was named after the French geologist Lousi Cordier (1777-1861). Cordier was professor of geology at the Muséum national d’histoire naturelle in Paris from 1819 to 1861 and developed the geological gallery in the museum. Cordierite is typically found in metamorphic rocks along with sillimanite, spinel, plagioclase feldspar and garnet. Gem quality material is rare and clean stones with good color can be quite beautiful. The violet-blue color is considered ideal, but iolite may also occur in ilght yellow, green, gray or brown. Iolite is strongly trichroic, meaning that it shows three colors when viewed from different angles. Iolite’s strong pleochroism earned it the nickname water sapphire, since from one direction iolite can appear sapphire-like blue and from another, it can appear as clear as water. From yet another angle it can appear a light golden color. The video below shows this pleochroism quite well.

Gold

Because of the softness of pure (24k) gold, it is usually alloyed with base metals for use in jewelry, altering its hardness and ductility, melting point, color and other properties. Alloys with lower carat rating, typically 22k, 18k, 14k or 9k, contain higher percentages of copper or other base metals or silver or palladium in the alloy. Copper is the most commonly used base metal, yielding a redder color.

Silver

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.
