The bottom bead is a 18x10mm flat teardrop the color of turquoise, but I don't know if it's actually turquoise or not. Center charm is a 1/2" (12mm) pewter knot with no beginning or end, symbolizing eternity and infinity in Celtic folk lore. The four simple loops are called a quaternary design, which variously can mean the four seasons, four directions, or four elements (Earth, Air, Fire, and Water.) Top bead is brown, teal-green, and gray-white loosely striped African sand-cast. Accents are dark green and mauve agate. 21" (67cm) long lead-free nickel-free chain with a 2-5/8" (63mm) center drop. Gift-ready in either an organza bag (default) or gift box upon request. Packaging styles change with availability.
