Anchor charm pendants in solid 14K gold and .925 sterling silver. Many are engravable on the back — the product page says which.
What the anchor means. Hope and steadfastness, from Hebrews: an anchor of the soul, sure and steadfast. Early Christians used it as a disguised cross, which is why it still turns up in devotional jewelry as well as nautical.
Styles. Plain anchors, anchors with rope worked around the shank, and anchor-and-cross combinations. Some carry a small heart at the crown for the faith-hope-charity set.
Who buys them. Sailors and boat owners, but also as a steadiness gift — someone who held firm through something.
