You have discovered your girlfriend’s ring size. You have shopped around for affordable engagement ring sets. You have picked out the perfect diamond cluster engagement ring. Now it is time to plan the perfect proposal. Here are a few ideas to get you started.

1. Give her the best gift of her life.

Collect square boxes of all sizes, from very large to very small. Put the diamond cluster engagement ring into the smallest box and wrap it. Tape a note on the outside that says one of your favorite things about your girlfriend. Put the wrapped box inside of the next largest box and wrap it. Write another note. Continue to nest the box into larger boxes and wrap with pretty wrapping paper topped with a sweet note. Once you have wrapped the largest box, tie it with a big bow and give it to her for her birthday. Or slip the engagement ring into the toe of her Christmas stocking and cover it with other gifts before hanging it back on the mantel.

2. Plan a picnic.

Ask your girlfriend to meet you for a picnic at your favorite park. Pack a picnic basket with your girlfriend’s favorite foods. Fill a cooler with ice and a bottle of champagne or sparkling cider. Bring a big picnic blanket to sit on. Don’t forget to bring her diamond cluster engagement ring in your pocket. Make a toast to your future together and pull out the ring to propose before you eat. Or have a local bakery create a cake or cookie with your proposal written in icing, and present it at the end of your meal.

3. Make memories at the movies.

Plan a dinner-and-a-movie date. Take your girlfriend to her favorite restaurant and go all out. Order an appetizer, wine, and dessert in addition to the meal itself. Next, take her to see a romantic movie at the theater. Be sure to sit on her left. Hold her hand during the movie, and at one of the most romantic moments of the movie, use your other hand to slip her diamond cluster engagement ring out of your pocket and onto her finger.

4. Put it in writing.

Based on your girlfriend’s interests, think of a creative way to put your proposal in writing. If she loves the ocean, plan a day at the beach when you will write the proposal in the sand. Does she spend a lot of time at the computer? Write one word on each post-it note to spell out “Will you marry me?” Stick the notes along the top of her computer monitor. Is your girlfriend a word lover? Create your own crossword puzzle with a proposal hidden in the clues to slip inside the morning newspaper. Or write a proposal with a magnetic poetry set on the refrigerator.
