4th Anniversary
gemstone: Blue Topaz.
Four years — blue topaz, the ordinary year made luminous
Quick answer
The 4th anniversary gemstone is Blue Topaz. The 4th anniversary gemstone is blue topaz, and year four is exactly the year for it: the jubilees are decades away, nothing round or famous happens — it is the ordinary year, the one marriages are actually made of. Blue topaz takes that year and turns it sky-colored. One honest fact worth knowing before you buy: nearly all blue topaz is colorless topaz given its blue by irradiation in a lab — a standard, stable, fully disclosed treatment the entire industry runs on, and the reason a large vivid blue gem can cost less than dinner.

4th anniversary FAQ
What is the gemstone for the 4th anniversary?
The 4th anniversary gemstone is blue topaz. Fruit and flowers are the traditional fourth-year gifts; blue topaz is the assigned stone — the December-born blue that delivers the largest, most vivid carats per dollar of any mainstream gem.
Is treated blue topaz still a real gemstone?
Yes. The stone is genuine topaz; its blue comes from safe irradiation followed by heating, a permanent industry-standard treatment — natural blue topaz barely exists, which is exactly why untreated deep-blue stones command collector prices. What you should never accept is glass or coated simulant sold as topaz: buy from sellers who state the treatment plainly.
