The right necklace or pendant will complement whatever she wears. A necklace, in addition to being a fashionable gift, allows you to perform the classically romantic gesture of putting it around her neck for the first time. A necklace, in general, is any type of chain or length of precious metal or gems. They are also available in pendant styles, which typically feature a single diamond, gemstone or fine metal design.

Metal Chain

Chains are appropriate for any occasion. A Gold choker chain will add a touch of radiance. Consider giving her an 18-inch white gold, yellow gold or rose gold chain to add visual interest to her outfit.
When choosing a necklace or pendant, keep in mind that the length will dictate where it will sit on her chest.
16 inches: The length of the choker is just above the collarbones. Her neckline is highlighted.
18 inches : falls below the collarbones. The most commonly used length.
24 inches: opera length wear over a blouse or dress.

Solitaire Diamond Pendant

A solitaire pendant's simple design allows all attention to be drawn to a stunning diamond, pearl, or gemstone. These classic pieces can be worn with either a dress or jeans. You can choose a diamond and setting to create a one-of-a-kind piece of jewelry.

Prong Setting Solitaire Diamond Pendant.

The prong setting is the most common type of setting for a solitaire diamond. The prongs that hold the diamond in place are open, allowing the most light to enter of any of the settings. It is suitable for most diamond shapes and is available in a variety of finishes.

Bezel Setting Solitaire Diamond Pendant

A bezel setting, as opposed to a prong setting, is one in which a metal band completely or partially surrounds the diamond, securely holding it in place. If you value safety, a bezel setting is the way to go. Bezel settings have a more traditional appearance and are frequently seen on vintage diamond necklaces because they are a more secure way of setting a diamond.

Halo Setting Pendant

A halo ring is a setting that surrounds a stone with a pendant of round pavé or micro-pavé diamonds. A halo setting can also help you save money by making the center stone appear up to a half-carat larger. With halo pendant, you have a lot of options. The halo that encircles the center stone can be round, squarish, or diamond-shaped. The metal can be white, yellow, or rose gold.

Choose Diamonds For Pendant

When choosing a diamond pendant, make sure to select a high-quality, well-cut stone. A diamond with a high level of fire and brilliance will sparkle far more than a diamond that has been poorly cut.
Cut:
A well-cut diamond maximizes the amount of light that strikes each pavilion, reflecting it back to your eye through the diamond's table and crown. Excellent and Ideal diamonds are the best cut stones, depending on the diamond's shape and the certifying body—though you'll still need to examine the diamond closely using high resolution imagery.
Color:
Most pressingly, make certain that the diamond appears white in comparison to its setting.
Clarity:
Clarity is even more important in pendant diamonds than in rings because they are worn directly in the line of sight. When looking at the diamond with your naked eye, check for blemishes and inclusions.
Certification:
Look for a diamond that has been certified by the GIA, AGS, or IGI.
