From completed designs to custom engagement rings, we have the perfect ring to help you pop the question. Explore some of our most popular styles below. What Makes a Diamond Unique? Every diamond is graded based on the 4 Cs:
Cut – The cut determines a diamond’s brilliance. A well-cut diamond reflects light beautifully, making it sparkle.
Color – Diamonds come in a range of shades. The less color, the more valuable the diamond—though fancy colored diamonds are uniquely prized too.
Clarity – This refers to the presence of natural inclusions. The fewer the inclusions, the clearer and more rare the diamond.
Carat – This is the weight of the diamond. While larger diamonds are rarer, beauty lies in the perfect balance of all 4 Cs.

How many carats should an engagement ring be?
Diamond carat refers to the weight of a diamond, though there is a widely understood link between a diamond’s carat weight and its size. You can refer to our diamond carat size chart to learn more about the general carat weight and size correlations for the most popular diamond shapes. .
A classic diamond engagement ring with one elegant center stone often weighs about one carat, while a slightly larger, two-carat diamond is also a popular weight. But there is no “right” size for a diamond or gemstone engagement ring. The best engagement ring carat size depends on your budget and the wearer’s unique personal style.
We offer a wide variety of natural and lab created diamond rings, making it easy to find the perfect fit for your special someone.
How much should I spend on an engagement ring?
The amount you spend on an engagement ring is a personal choice that should take your finances and priorities into account. Beautiful men’s and women’s engagement rings are available for a range of budgets, and our experts are happy to help you find the best value at a price you’re comfortable with.
What should I know before buying an engagement ring?
When shopping for a gemstone or diamond engagement ring, keep in mind that the shape and cut of a stone are more important than its size. Understanding the 4Cs of diamonds and the details about gemstone qualities can help you create the perfect ring for your partner.
Even more important is the wearer’s personal style and lifestyle. Choose a gemstone or diamond ring that fits the wearer’s personality, whether that’s a pink cushion diamond in a vintage gold setting, a lab-grown diamond ring or a classic round diamond in a sleek and modern platinum setting. And if the wearer is very active, choose an engagement ring with a low profile.
How quickly can I get an engagement ring?
We offer fast shipping on our engagement rings. Should you need your ring in a hurry, consider our ready to ship engagement rings.
How can I make a ring more affordable?
Whether you’re choosing earth created or lab-grown diamond rings, there are many ways to stay within your budget. Options such as white gold, fancy-shaped diamonds or lab created gems are popular choices for creating a stunning ring that’s more budget-friendly.
What kinds of engagement ring styles are popular today?
Popular styles include engagement rings for women that feature a prominent center stone such as solitaire and halo rings. Pavé, twist band and milgrain designs are also in-demand styles. Lab-created diamond engagement rings are also growing in popularity.
Many of today’s emerging women’s engagement ring trends feature non-traditional takes on this symbolic jewelry style. This includes two stone engagement rings, hidden halo rings and creative unique engagement ring settings.
What metals are used in engagement rings?
A popular engagement ring metal among Blue Nile customers is definitely platinum (or white gold for people who want a platinum-look at a lower cost). Over the last few years, however, rose gold engagement rings are a fast-rising trend. Rose gold was often used in settings in the late nineteenth century, and is appreciated today for its naturally romantic appeal that particularly suits rings with vintage-inspired styles. Most recently, yellow gold engagement rings are capturing the attention of people who appreciate the way this metal’s beautiful warm glow complements engagement ring settings with colored gemstones.
What are the 4Cs?
The 4Cs are the four main quality factors that determine the value of a diamond: color, cut, clarity and carat. The sparkle of a diamond comes from its cut and symmetry, while the carat size determines how big it will look on the wearer’s finger. Use the 4Cs to help guide your engagement ring choice, but—as always—the “right” ring is the one that reaches out to you, whether or not it’s deemed a “perfect” stone by experts.
