Few things can measure the value of a relationship to a woman like the gift that you decide to give her for her birthday.

Diamonds are a girl's best friend, as the old cliche goes, but nice jewelry isn't always in the budget. So if you're shopping for a woman, any woman -- wife, daughter, girlfriend, grandmother -- it's going to be thought that counts, not necessarily the price tag.

Here are a few ideas that will score you points with your favorite woman on her birthday without blowing a hole in your bank account.

Flowers

If you have $50 to spend, you can buy you a very nice foral display for your woman. At first glance, it seems very easy, but flowers can be screwed up.

One thing to consider is the meaning of the blooms. You should consider the depth of the relationship with the woman before you purchase them. Different flowers have different meanings.

"Many of the romantic sentiments conveyed by flowers seem old-fashioned and out of date by today's fast, cheap and easy standards, but women still like this stuff," suggests the Single Guy Advisor blog.

Also, don't overplay your hand with flowers. If you bought them for her on Valentine's Day and on her birthday last year, it could appear that you are getting lazy.

Candles

Scented candles can also be a successful gift. They can help strike a variety of moods. from sensual to celebratory.

"No other gift can be enjoyed extensively and can provide the light, scent, color, and warmth quite the way a candle can," according to the Hot Candle Home Gift blog.

Look closely at details when purchasing candles, such as color, aroma and size. These details could make or break the gift.

Arranging a variety of candles in a gift basket could be the added touch that really makes the gift sing in the eyes of the woman you're buying them for.

Wine

A fine wine can have a lot of sentimental meaning to a woman. But, be sure to spend your entire $50 budget on the bottle. You can by bottles of wine in some places for as little as $6 and an assertive woman can easily sniff out a cheap bottle of wine.

One option to make the gift even more meaningful is to add a personalized label. There are dozens of sites around the web that allow you to add your own photo to a bottle of wine. Some will sell you the wine and the bottle label together, others will allow you to simply buy personalized labels and you can add them to a bottle you purchase.

Either way, it's a great way to show the woman in your life that you put time, thought and effort into her gift.

Personalized Book

Heading to a bookstore and buying a book by your woman's favorite author is nice, but wouldn't it be nicer if she was the star of the book?

Businesses that give you the ability to produce a personalized picture book have skyrocketed over the last few years. You likely have plenty of photos of your women, so put them on the page to show her off and score big points.

Most offer the ability to upload photos and design the book right online.

Gifts For Under $20

It could be hard to impress some women with a birthday gift under $20, so your best bet is to go hyper-personal with a gift that truly shows how you feel about her.

Greeting Card

Cards are cheap, but it's what's in the card that counts. Think long and hard about the sentiment you are trying to convey with the card and what you write inside.
