Mother's Day, sixtieth birthday, the day she retires.
Her Tenderness is the piece I make most often for mothers. Rose quartz and strawberry quartz are warm without being sweet — they look like the inside of a peach. There's one moonstone hidden near the clasp; it does more work than its size suggests.
If your mother is the kind who doesn't wear pink, Slow Sunday is the alternative — pearl and moonstone, quieter, more contemplative. Best for the mother who reads on Sunday mornings.
