An anniversary gift made from a stone she already owns.

The gift that lands most often is her own stone, remade into something she will wear again.

What people give.

From what people come back and tell us afterwards.

Her original engagement stone, reset: A milestone anniversary, the same diamond, a setting chosen for the person she is now. This is the one that gets the reaction.
A piece from a relative, made wearable: Something inherited that has never left its box.
A colored stone that means something: A birth month, or the color of somewhere you went together. See colored stones.
Something simple, worn daily: Not every gift needs to be an event. Plenty of the best ones are small.

Anniversaries and birthdays do not move, so say the date first and we will tell you what fits inside it.

A remount needs the piece: Which means getting it off her hand for a while. Most people manage this over a work trip.
Bring a photograph if you cannot bring the piece: Enough to talk about what is possible.
We will say no to a date we cannot meet: At the first meeting, while there is still time to change course.
