Want to really impress a Gemini? Ultimately, the sign of the Twins is not materialistic, so you need to spend much to make them feel special. But if you have the means and really want to knock their socks off, here are a few suggestions:
1. Front-row seats to a concert or other live performance. Find out their favorites and score those highly-coveted tickets as soon as they go on sale.
2. A first-edition copy of their favorite book, or a hardbound copy signed by the author.
3. A vacation. Airfare to a destination they're dying to visit... add accommodations and a car (they will want to explore) and you're beyond golden.
4. A membership to their favorite museum, organization, or cultural attraction. Even better? VIP status and a donation to it made in their name.
