Features to Consider When Buying Diamond Rings for Couples (Buyer’s Guide)

Is it about time to start a diamond couple ring shopping? Buying diamond couple rings can be a crazy time to do by yourself or with your partner. It’s easy to get caught up in the romance, but keep in mind that buying any ring is a considerable expense, so you need to make sure you are doing it right.

Budget

Depending on your chosen retailer, a simple platinum band or a plain 14-karat gold ring can cost around $1,000. Engravings or embellishments like diamonds can quickly add up to the cost. As much as possible, factor the features you want for your diamond couple ring into your budget if you plan to customize your matching bands with any of these extras. 

The engraving price is often based on whether it is engraved by machine or hand (pricier option), the number of characters, and the font used.

Lifestyle

Since you’re going to wear a diamond couple ring almost every day, your goal is to pick something that will seamlessly become a part of your day to day life. For those who play musical instruments or sports, a ring with slimmer and rounded edges or appropriately called the “comfort fit,” is the best choice.  

For those who frequently work using their hands, you need a simple, solid metal ring. You have to avoid gemstones as much as possible as it can easily come loose, including carvings, as it acquires dirt on its engravings. Meanwhile, super active folks should go for incredibly durable platinum rings. This way, when the right gets scratched, the metal doesn’t wear away, and it is merely displaced.

Design

When choosing a design for a diamond couple ring set, always pick a design that complements you and your partner’s lifestyle. You can choose a matching couple ring set, especially if both of you share the same tastes.

You may also consider buying complementary couple rings that may differ from each other but have similar features that reflect your union as a couple. Otherwise, you may create a customizable couple ring set according to you and your partner’s style preferences.

Metal

When couples get matching ring sets, they tend to pick the same ring but with different metal colors. Plenty of jewelry retailers do this as it creates a unique look for the couple ring set.

Choosing a different metal for the band ensures a unique appearance for the same ring. Couple rings, even wedding bands are available in different metal colors, such as platinum, yellow gold, white gold, silver, and rose gold. Although platinum resembles silver, platinum is more expensive since it is rarer and has a greater density.

Diamond

When buying a diamond couple ring set, you may also want to look for a precious stone to add sparkle to the rings. Additional stones are the newest trend in the couple ring category, often combining diamond shapes. One great example is an emerald-shaped diamond ring for men, a stunning match with a crossover ring with multiple emerald-shaped diamonds.

Setting

As much as possible, choose your ring’s setting wisely since the setting should represent a harmony between the couple rings. More often, couples choose a channel setting or a classic prong setting for the couple ring set. You may also like to explore other designs with subtle details to add symmetry between the couple rings. 

Placement

Since couples will probably wear the rings most of the time, you have to ensure that both rings are ideal for everyday wear. Traditionally, the ring finger is the ideal placement for all types of rings, including wedding and couple engagement rings. However, with diamond couple rings, you are free to wear it on any of your fingers.  

Maintenance

To keep diamond couple bands clean and sparkling, you have to wash and soak it in warm, sudsy water. Afterward, you can gently brush it using an eyebrow brush or a soft toothbrush. Using a brush with tough bristles or applying too much pressure can loosen the stone from its setting.

Rinse the rings and pat it dry with a soft, lint-free cloth. If it’s too much upkeep for you, you may choose fuss-free platinum or gold couple rings. Maintenance is fairly easy. You can simply rub it with a chamois or a soft, lint-free cloth. 

Size

When you have your ring on, your fingers tend to contract and swell from heat, water retention, cold, or weight gain. However, it is possible to find the correct size that suits well at all-weather changes. When your body is at a calm state with a normal body temperature, you can schedule the final right fitting.  

As much as possible, you should never finalize the right fitting first thing in the morning (you retain water when sleeping), right after your workout or exercise (fingers tend to swell), or when you’re cold or extremely hot (your hands may expand or shrink). 

Certificate

Since you’re buying diamond couple rings, you need to make sure the diamond has a matching certificate. Diamonds should be laser inscribed on its girdle, which you can check with a jeweler’s loupe. Many have inclusions on the diamond, so you have to check if it matches the imperfections stated on the certificate.

Carat Size

Some couples prefer either a larger or a whiter stone, while others want an absolute, clearest possible diamond, despite its carat count. If size matters to you and your partner, you should keep an ideal carat size in mind when looking for diamond couple rings. You should also be more flexible about the available elements that suit your budget.

Quality

Quality control always applies to all types of rings, not just wedding or engagement rings. You have to make sure that the ring you’re going to buy has two marks within the band: the manufacturer’s trademark and the quality mark, PLAT, or 24K, proving the metal quality).


Conclusion

Couple rings have become so ingrained in the dating culture that many have dreamt of wearing a diamond ring, especially those in a committed relationship. As a result, customers tend to become more specific with the ring they are planning to buy since a simple band with a solitary stone tends to be more traditional.

The Petite Twist Diamond Eternity and Lathe Emery Comfort Fit Set in 14k White Gold from Blue Nile take the crown as the best diamond ring for couples. These two rings are the top bestselling couple rings on Blue Nile’s website.

FAQS (Frequently Asked Questions)

What is the difference between a promise ring and a diamond couple ring?

Many get confused with the terms “couple ring” and “promise ring,” as they are often used interchangeably to identify rings exchanged between couples who are not yet engaged.

Promise rings for couples symbolize love and commitment. Although they are available in various metals, promise rings are often made from the most precious metals. On the other hand, diamond couple rings are worn by couples designed to be worn as fashion jewelry or just for fun. They often have artistic patterns with cool designs and unique materials.

However, jewelry retailers have modernized a diamond couple ring’s overall features by producing rings made of diamond and precious metals.

In short, promise rings are worn by couples for a specific purpose, while couple rings tend to be more generic with a less specific form of similar rings for couples.

What makes James Allen different from other fine jewelry lines and retailers?

Whether online or traditional brick-and-mortar, what sets apart James Allen from other jewelry retailers is their proprietary Diamond Display technology. This unique feature allows customers to examine a specific stone in their inventory using a magnified 360° view. 

With the Diamond Display technology, it allows the customers to see for themselves the quality of a diamond ring or any jewelry, rather than relying on a sale associate’s opinion or certificate. 

Since James Allen inspects and photographs thousands of diamonds and jewelry each day, they have an earlier chance to handpick and feature all the very best diamonds on their website. Plus, they can offer a large selection with better value than traditional jewelry stores.

What are the factors that customers are often unaware of when shopping for diamond rings?

When buying diamond rings, customers often start their purchase decision with little to no knowledge about diamond rings. They tend to educate themselves as they go through the buying process, which often spans a few months.

One of the most significant factors that they are unaware of is that the diamond rings they bought from brick-and-mortar retail stores are also the same ones sold on online jewelry vendors with a 30 to 50% discount. 

Although customers cannot see the actual diamond ring on jewelry websites, customers assume that online vendors offer 30 to 50% discounts on their jewelry due to its poor quality. This example is a common misconception among online jewelry vendors.

Online jewelry vendors photograph and keep an inventory of their diamonds to allow their customers to compare jewelry in great detail and choose the best quality diamond that suits their budget.
