Paraiba is a type of tourmaline of a particular turquoise-blue color, originally found in Paraiba, Brazil. Since it was discovered, tourmaline of a similar color has been found elsewhere and also called Paraiba tourmaline. Since it is rare, Paraiba tourmaline is expensive. Soon, people began selling other blue stone of a similar color as “paraiba apatite” or “paraiba topaz”. This is creative marketing and has nothing to do with the original deposit of tourmaline found in Brazil.
Refers specifically to oxidation or corrosion on metal surfaces like copper, but also generally to a sheen on any surface that makes it look old and used (the “antique” look). You can create patinas on metal jewelry with chemical solutions and corrosive materials like ammonia or vinegar. Be sure to understand the safety concerns before trying this, both in terms of ventilation and not damaging your jewelry. photo credit
A heavy, malleable, corrosion resistant, grey-white precious metal. Platinum is more precious than gold. Though platinum beads can be purchased through specialty dealers, platinum is rarely used in typical beading applications and is found mostly in fine jewelry. For example, the frame of the Crown of Queen Elizabeth, the Queen Mother, is made of platinum. But like all metal names, it is sometimes used in color descriptions rather than literally. photo credit
