This means the bracelet's base is sterling silver, but it also features a layer of 10 karat gold that makes up 1/20th of its weight, providing a more durable gold finish than simple plating.  Here's a breakdown of each marking: 925: This is the mark for sterling silver, meaning the metal is 92.5% pure silver alloyed with other metals, typically copper, for strength.  1/20 10K: This signifies a "gold-filled" item, which has a thicker, more durable layer of gold bonded to a base metal compared to gold plating. 1/20 means that the gold layer constitutes 1/20th (or 5%) of the item's total weight. 10K indicates that the gold layer is 10 karat gold, which is 41.7% pure gold.  AU: This is the chemical symbol for gold, appearing on the piece to confirm the presence of gold.
