Forty years of marriage — the ruby anniversary — celebrates four decades of love that has weathered everything. Both the traditional and modern themes are ruby, marking the same celebration. Ruby symbolizes the deep, enduring fire of long-term love.
Why these symbols?
Ruby was chosen because of its color (the deep red of the heart), its rarity, and its hardness — second only to diamond among gemstones. The unified traditional/modern theme reflects how universally significant the 40th anniversary has become. Many couples celebrate with a ruby renewal of their wedding bands.

Connecting Beyond the Gift
Anniversary gifts mark the year — but the work of building a marriage worth celebrating is daily. Many couples use anniversary milestones as a moment to recommit to small daily rituals: a weekly check-in, a daily question, expressing one specific appreciation.
Connected was built specifically to support these daily rituals. Our relationship check-in questions include several specifically designed for anniversaries — to help couples have the conversations they often skip.
Frequently Asked Questions
What's a meaningful gift for the 40th anniversary?
A meaningful 40th anniversary gift typically reflects either the traditional (ruby) or modern (ruby) theme — but the most meaningful gifts go beyond the theme to reflect something specific about the relationship. A handwritten letter, a custom photo book, or a recreated date often outrank expensive items in long-term memory.
What is the traditional 40th anniversary gift?
Ruby. Both the traditional and modern themes are ruby, making the 40th anniversary universally a 'ruby anniversary.' Common gifts include ruby jewelry, ruby-themed décor, and ruby-tinted experiences.
Why is the 40th anniversary the ruby anniversary?
Ruby was chosen for its red color (the heart's stone), its rarity, and its hardness — second only to diamond among precious stones. The 40th anniversary marks four decades of love that has demonstrably endured, the same qualities ruby represents.
How much should you spend on a 40th anniversary gift?
The 40th is a major milestone — many couples invest $500–$5,000+, often combining ruby jewelry with a major celebration like a vow renewal or significant trip. The exact amount matters far less than the intentionality of the celebration.
The Bottom Line
The 40th anniversary's traditional theme of ruby and modern theme of ruby give you a starting point — but the meaning comes from how you adapt them. Whether you go classic, get personal, or invent something new, the most important thing is that you marked the year intentionally.
