•The name ruby comes from the Latin word ruber, which means “red”. •Ruby is the birthstone for July and the gem for the 15th (in the U.S.) and 40th anniversaries. •Ruby is the most valuable variety of the corundum mineral species. •Chromium is the trace element that causes ruby’s red, which ranges from an orangey red to a purplish red. •The strength of ruby’s red depends on how much chromium is present—the more chromium, the stronger the red. …. The Carmen Lúcia Ruby. The 23.1-carat Burmese ruby, set in a platinum ring with diamonds was donated to the Smithsonian by businessman and philanthropist Peter Buck in memory of his wife Carmen Lúcia. The stone was mined from the famous Mogok region of Burma in the 1930s. While sapphire, emerald and diamond gems weighing hundreds of carats exist, high quality Burmese rubies larger than 20 carats are incredibly rare.

•Feldspars are the most diverse and widespread minerals in the earth’s crust. •Moonstone is the most familiar gem-quality member of the feldspar group. •Moonstone is a part of the feldspar group, and is a variety of the species orthoclase within that group. •Moonstone is a composite of two feldspar minerals, orthoclase and albite. After the orthoclase and albite have come together they cool and separate into alternating layers that are stacked on each other. •Moonstone is known for having an ethereal misty glowing look. This phenomenon is called adularescence.

•Adurlarescence is occurs when light falls between the stacked layers of orthoclase and albite and scatters it.

•Rainbow moonstone has a multicolored adularescence over a light bodycolor. However it is not actually moonstone. It is a variety of labradorite (often from Madagascar) and rainbow moonstone is a trade misnomer.

*The necklace features moonstones and labradorite set in silver. It was made by Danish Designer Georg Jensen between 1915-1927 and currently resides at the Victoria & Albert Museum.*
