Ultimate Diamond Pendant Buying Guide

A diamond pendant is a piece of jewelry that features a diamond or diamonds set into a metal frame that hangs from a chain, usually made of gold, platinum, or silver. Often worn as a statement of elegance and sophistication, diamond pendants make for timeless gifts and can suit various occasions, from anniversaries to birthdays. When purchasing a diamond pendant, there are essential factors to consider, such as the 4Cs—cut, color, clarity, and carat weight—to ensure you get the best quality diamond for your budget. Additionally, the setting and style of the pendant are vital considerations; whether you prefer a classic solitaire design or something more intricate, the setting should securely hold the diamond while complementing its brilliance.

Bottom Line Recommendation

A diamond pendant makes for a stunning and meaningful gift for any special occasion. To ensure you purchase the most beautiful necklace, review the diamond closely. Look for a diamond that is clean of blemishes and inclusions—and one that offers plenty of brilliance (also known as sparkle). Most importantly, choose a diamond from a reputable and reliable vendor like James Allen or Blue Nile. When it comes to style, consider the preferences of your loved one. Diamond pendant designs range from solitaire pendants set in 14K white gold like this one from James Allen to those in yellow gold settings like this example from Blue Nile.

    Here are some curated Diamond Pendants from our favorite jewelry retailers:

What is a Diamond Pendant?

A diamond pendant is a necklace with a central diamond that’s attached by a small loop to a jewelry chain made of precious metal (usually gold or platinum). The word ‘pendant’ comes from the Old French “pendre” and Latin word “pedere”—both meaning “to hang down.” Diamond pendant necklaces are often given as a symbol of love, specifically eternal love.

What is a Solitaire Pendant?

A solitaire pendant is a necklace with one gemstone—usually a diamond. The gemstone stands alone on a jewelry chain, typically made of white gold, yellow gold, or platinum. Solitaire pendant necklaces range in style from a 0.3 carat solitaire pendant in platinum like this one from James Allen to this1.5 Carat solitaire pendant in white gold from Blue Nile.

Where to Buy a Diamond Pendant

Similar to buying a diamond ring, it’s critical that you purchase a diamond pendant from a reputable vendor. From our extensive experience, we’ve learned that the following vendors are the most trustworthy and reliable in the industry.

Diamond Pendant Settings and Designs

Several precious metals are available for your chain and pendant. You can select 14K or 18K gold as both are durable enough for everyday wear. Gold colors include yellow, rose and white—and the decision should be made with the wearer’s preferences in mind. Pendant chains also come in platinum, though the price is higher and often not necessary.

Popular setting styles for pendants usually include prongs (typically four) because prongs allow the most light to enter the diamond and reflect back to the eye. 

Other designs include halo settings, and bezel settings. Metal surrounds the stone in a bezel setting like in this 14K white gold pendant.

Most importantly, be sure to purchase your diamond pendant from a reliable vendor. We strongly recommend choosing a vendor you can trust, like Blue Nile or James Allen.

Best Diamond Pendant Designs for Inspiration

Diamond pendants come in a variety of styles and settings. Here we offer inspiration on everything from solitaire designs to halo pendants.

Diamond Cross Necklaces

Diamond cross necklaces feature a cross shape made out of diamonds that’s attached to a chain. Diamond crosses range in style, size and color, though this 14K white gold diamond cross necklace from James Allen is a prime of a classic diamond cross pendant. There are women’s and men’s diamond crosses, ranging from petite designs to signature styles totalling 2 carats like this one from Blue Nile. 

For diamond cross pendants, we recommend 14K or 18K gold chains because they’re durable but not as expensive as platinum. A gold diamond cross is timeless and will last for many years of everyday wear.

Dancing Diamond Necklaces

Dancing diamonds are a unique design with a setting that allows the center diamonds to move or “dance.” As the diamond continually moves, it catches light from various angles, allowing it to showcase its brilliance and fire. Dancing diamond pendants range in size and style, from classic yellow gold designs to modern white gold settings. 

In addition to dancing diamond pendants, you can find dancing diamond earrings, dancing diamond heart necklaces and dancing diamond rings.

Diamond pendants make for beautiful and memorable gifts. Because of their classic design and popular appeal, diamond pendants are often kept as family heirlooms and passed down for generations.

Consider gifting a diamond pendant for any of these special occasions:

  • Wedding anniversary (i.e. 5th, 10th, 15th)
  • Birthday
  • Valentine’s Day
  • Celebration of an exciting milestone
  • Graduation (high school, college, graduate school, medical school)
  • Birth of a child (push present)
  • Retirement
  • Job promotion
  • Christmas, Hanukkah and other holidays
  • Wedding day gift (for bride, mother, mother-in-law, grandmother)

How to Choose a Diamond for Your Pendant

When it comes to selecting a diamond pendant, be sure to choose a high quality, well cut stone. A diamond with a high level of fire and brilliance will sparkle far more than a poorly cut diamond (which will end up looking dull).

For pendants, use the following parameters to assess a diamond:

Certification: Look for a diamond with a GIA certification. This is the most reliable grading entity, helping to ensure you get the quality you’re promised.

Diamond cut: A diamond that is cut well maximizes the light that strikes each pavilion—reflecting it back through the diamond’s table and crown to your eye. Depending on the diamond’s shape and the certifying body, Excellent and Ideal diamonds are the best cut stones—though you’ll still need to review the diamond closely through high resolution imagery. You can also ask for .

Diamond color: A diamond’s color grade refers to its lack of color. As the AGS explains, diamonds that are colorless command the highest value, with brown or yellow diamonds less expensive. Most importantly, ensure the diamond looks white in relation to its setting.

Diamond clarity: Because pendants are worn directly in the line of sight, Clarity is even more important in pendant diamonds than in rings. Inclusions in a diamond can reduce its clarity and beauty. As this GIA guide notes, inclusions develop when small crystals become trapped in a diamond as it forms inside the earth.

Review each diamond carefully to ensure no blemishes and inclusions are present when looking at the stone with the naked eye. Use a vendor with incredible video technology like James Allen or Blue Nile to have a strong advantage when assessing a diamond’s Clarity. If you’d like an expert evaluation, and we’ll review the diamond for you.

Diamond shape: The shape you choose for your diamond pendant—whether it’s round, oval or heart-shaped—is primarily based on personal preference. Look at a variety of shapes to see what matches the wearer’s style the best. The most popular and timeless shape for a pendant is a round diamond.

How Much is a Diamond Necklace Worth?

Diamond necklaces range in value depending on the number of diamonds, the diamond carat weight, diamond cut quality, and type of setting. For instance, this three-stone diamond pendant in white gold from Blue Nile might cost $6,500, while a might cost $2,900. A can cost $40,000.

If you were to resell your diamond necklace, it would be worth much less than what you paid for it. Just like selling diamond rings, a diamond necklace shouldn’t be viewed as a financial investment.

How Big is a 1 Carat Diamond?

A 1 carat diamond isn’t a certain size, but a certain weight. A 1 carat diamond is equal 200 milligrams, or 0.2 grams—roughly the same as a quarter of a raisin. Depending on the shape of the diamond and the cut, the size appearance will differ slightly. For instance, this 1 carat oval diamond from James Allen may appear slightly larger than this 1 carat round cut diamond also from James Allen.

How Much is a 1 Carat Diamond?

1 Carat Diamonds can range dramatically in price, depending on cut quality, color, shape, and clarity. For instance, a dull 1 carat round diamond like this from James Allen might only cost $4,590 while a stunning 1 carat round diamond from James Allen’s True Hearts collection might cost $7,540.

Above all, we recommend looking for a well-cut diamond that offers brilliance and sparkle. It’s more important to find a beautiful stone than achieve a certain carat weight. For help in selecting the most stunning diamond for your budget, reach out to our experts.

Best Chain and Clasp for Diamond Pendants

The best chain type for pendants is a cable chain because it’s strong, elegant and versatile. That’s why most people choose a cable chain for their pendant. 

The best precious metal for diamond pendant chains is 14K or 18K gold because it’s durable and beautiful, but not as expensive as platinum. You can find 14K and 18K gold chains in yellow gold, white gold and rose gold. This 18K white gold halo diamond pendant from James Allen is a stunning example of a diamond pendant chain. 

The best type of clasp for diamond pendants is a lobster clasp, because it’s secure while opening and closing easily. This three-stone drop pendant from Blue Nile features a lobster clasp in 18K gold. Other clasps for diamond pendants include spring ring clasps, barrel clasps and magnetic clasps.

How to Determine Chain Length

The length of your chain will be based primarily on personal preference and what’s offered by the vendor. Standard chain lengths range from 16 to 24 inches, with 18 inches being the most common.

With a 16 inch chain, the diamond will rest above the sternum (unless the person has a thin neck, then the diamond will hang lower). With an 18 inch chain, the pendant will likely fall right about at the sternum—and a 22 or 24 inch chain usually puts the diamond lower than the sternum.

Consider the person you’re buying for and their style. When in doubt, measure the chain lengths of their favorite necklaces.

How Many Carats Should a Diamond Pendant Be?

How Many Carats Should a Diamond Pendant Be? 

Bringing home the diamond pendant of your dreams is an exciting experience. A diamond pendant is a timeless piece of jewellery and a glamorous addition to any collection, but when you actually decide to pick a diamond pendant, things can get a little tricky. First, they come in various shapes such as oval, pear, and  circle diamond pendants. Once you’ve decided on shape, there are many other aspects to consider, including carat.

Overall, there are four objective measurements that will help you choose a diamond—carat, cut, colour, and clarity—but carat is often the most discussed attribute. 

What is Carat? 

Carat is a measure of the weight of a diamond. It should not be confused as a measure of its size, as a one-carat diamond can vary in dimension. Unless you pay close attention to the measurements of your stone, you can end up paying for diamond weight you don’t see.

Importance of Carat

When picking out jewellery, one of the biggest concerns is what carat diamond to purchase. This requires balancing your budget, style, and expectations carefully. At Holloway Diamonds, we will try to help you navigate the process using the following information about different carat sizes for diamond pendants. 

0.05 to 0.10 Carats 

Very small diamonds at the base of the throat add a little sparkle and a lot of elegance to any outfit. This weight is ideal for those who prefer delicate jewellery. 

0.25 Carats

At 0.25 carats, a round diamond measures about four millimetres in diameter, a great size for a noticeable but modest pendant. This size could be an ideal option as a dress-up to dress-down piece for someone with a petite frame. 

0.5 Carats 

A half-carat diamond will be noticeable and perfect for both everyday wear and special occasions. A half carat round diamond, measuring about five millimetres in diameter, has plenty of sparkle. 

0.75 Carats

With a diameter of about 5.7 millimetres, a diamond of this size is sure to incite compliments. Although this weight of stone still works from dress-up to dress-down, a 0.75-carat diamond has a lot of sparkle and may be too much for certain outfits. 

One Carat 

For those that need an element of glamour, a one-carat diamond might be the ideal size. At about 6.5 millimetres across, this might be the upper limit of what you can pair with jeans and a t-shirt.

1.5 Carats and Larger 

At larger sizes, diamonds become very sparkly and can be too much for a casual outfit. Still, some enjoy the look of a 1.5-carat diamond pendant for formal events. 

Is Carat Everything? 

Definitely not! When it comes to buying the right diamond, carat is just one of many aspects to consider. The size and the final look of the diamond depends on several other factors such as its cut, shape, setting, colour, and clarity. Considering all these details can be a daunting task to the untrained eye, this is where we come in. At Holloway Diamonds, we can guide you through the process of choosing the right diamond pendant for you or your loved one. For any of your diamond-related questions—be it choosing which necklace to buy or how to prevent necklaces from tangling—our team at Holloway is at your disposal.
