Signet rings are a jewel box staple. Often they have a family crest or symbol on them, but sometimes just an initial, as with this one from Posh Totty Designs.

They note, “Stunning personalised signet ring made from solid 925 sterling silver. Each ring is engraved by our expert jewellers with your initial and a beautiful floral design. For that extra special touch, this engraved signet ring can be plated in 18ct Yellow Gold or 18ct Rose Gold. A unique gift for someone who loves something traditional with a modern twist.”

This is priced at £65 in sterling silver; add £10 for yellow or rose gold plating.
