According to InStyle Weddings, here are 10 top tips for buying the engagement ring:
1. Skip the Solitaire
There’s more than one way to wear a carat of diamonds on your finger.
A ring with a classic solitaire at this weight (right) will generally cost thousands. But a band covered with tiny pavé diamonds that add up to just under 1 carat (left) sparkles plenty and can cost up to 90 percent less than a ring with a big center stone.

2. Compare Settings
The way a diamond is framed can have a major impact on how big it looks. For example, a bezel—a thin band of metal that wraps around a gem—gives the illusion of a larger stone. These two rings both hold .25-carat diamonds, but the solitaire on the left seems more substantial than the prong-set one on the right.

3. Know Your Metals
Platinum and gold are the top choices for engagement rings. The former will cost you—a simple platinum band can cost nearly $600 more than a comparable one in gold—but many brides feel the price is worth it. Platinum is a far more durable metal. It will show fewer nicks and scratches, and platinum prongs will hold a stone more securely. As for color, some people believe that yellow gold casts an unflattering light on the diamond, while others prefer the hue’s warmth and traditional look.

4. Invest in Insurance
The cost of protecting yourself against loss or theft depends on several factors—including the value of your ring, of course, as well as where you live (major city dwellers will pay more). According to Donna Syverson, a spokeswoman for the national insurance firm Jewelers Mutual, your annual premium will be about 1 to 2.7 percent of the jewelry’s appraised value, even for rings that cost six figures.

5. Have Your Ring NumberedYour diamond’s certificate number (or jeweler’s designation) can be laser-inscribed on the side of the stone, allowing it to be positively identified in case of theft or after cleaning or repair. Such inscriptions, which are visible under magnification (shown at right for the ring below) don’t affect the gem’s value. They cost from $40 to $200 and offer more than mere peace of mind: Some insurance carriers will give policy discounts on inscribed diamonds.
6. Save Big with a Smaller Stone
Most couples look for diamonds in whole carat weights, but what you may not realize is that jewelers charge a premium for such stones. If you opt instead for a gem just under a carat (or under 2 or 3 carats, for that matter), the savings can add up to 30 percent. And the difference in size is so insignificant, you won’t be able to tell. Of the rings shown here, the top one features a 1.03-carat solitaire and costs $14,000; the solitaire at the bottom weighs .93 carats and will run you $11,000.
7. Dream Up a Custom Piece
Believe it or not, many reputable jewelers offer one-of-a-kind rings without charging exorbitant fees. Some companies require a minimum purchase or bill clients a small amount for preliminary work, such as drawings.

According to The Wedding Report, white gold and platinum wedding bands have now outpaced yellow gold by two to one in popularity. Platinum is especially popular because of its purity, rarity and durability. In addition, men’s rings are getting bigger and more intricate, with a rise in demand for engraved patterns, such as scrollwork or filigree. Men are also choosing rings that incorporate diamonds into the bands, particularly burnished-set stones that are set flush with the band instead of raised.
Ring designers are seeing colored gems and engagement rings with extra diamonds surrounding the larger stone as popular styles. Settings with elaborate and raised stones, and twisted wedding bands are also trendy. Colored stones and stacked wedding bands are alternatives to the traditional engagement and wedding band combination. Piling wedding bands on top of one another creates a striking look and paves the way for future anniversary additions, as well.
Recycling wedding rings is another growing trend, whether it be passing down family heirlooms or melting the metal of older rings and using it in a newly designed creation. Vintage-style bands and antique rings are also quite trendy for 2008. Detailed designs include scroll-like engraving, microset (tiny half-point) diamonds, delicate milgrain work, raised beaded edges, and filigree.
Antique rings with cushion and Asscher-cut diamonds, which were very stylish in the 1920s, are currently popular among brides. These diamonds are square-shaped and designed to reflect candlelight while drawing the eye into the stone. These cuts also complement pavé-set bands, which are currently trendy, as well.
Big, bold jewelry is also quite popular on the fashion runways this year, including wide bracelets, chandelier and long, thin shoulder-skimming earrings, as well as larger-than-life necklaces, such as chokers with six strings of pearls.
