18 Karat Yellow Gold
18k (75%) gold is the purest form of gold used for jewelry (pure 100% gold is 24 karats by definition). 18k means that 18 out of the 24 parts that make up the gold are pure gold. The most common hallmark stamps for 18 karat gold are 18K or 750 that indicate 75% gold purity. 18k yellow gold is an alloy made up of 75% pure gold and 25% alloy (12.5% copper, 12.5% silver).
Tourmalines come in a wide variety of exciting colors. In fact, tourmaline has one of the widest color ranges of any gem species, occurring in various shades of virtually every hue. Single color tourmalines are rare as most crystals have more than one shade. Tourmaline can be dichroic, meaning some stones appear to change color when angled. Tourmaline is durable, rating a 7 to 7.5 on the Mohs Scale. Rubellite is a name for pink, red, purplish red, orangy red, or brownish red tourmaline, although some in the trade argue that the term shouldn’t apply to pink tourmaline.
