How Much Does an Engagement Ring Cost?


When you hear the words diamond engagement ring, you may immediately think: what will it cost? It’s no wonder, because prices for everything seem to be rising, especially in the current economic climate. The price of a quality 2ct diamond can be $30kif it’s a mined diamond. A similarly-graded lab diamond will be about a quarter of that priceor less.

So, how much do engagement rings cost? The answer depends on a variety of factors, including the size and quality of the gemstone, the metal used in the ring's construction, the quality and design of the setting, any warranties included, and even where you live.

Let's dive in.


There are over a dozen “data points” on a diamond certificate that contribute to the price, and it’s true that carat weight is a major factor in the price of lab and mined diamonds. This is because it’s more of a challenge to create larger diamonds, whether in the lab or in the earth. The higher priced the diamond engagement ring, often the higher the diamond carat weight. But not always. 

By now you’re probably familiar with other quality factors that go into diamond pricing. Cut grade, color, and clarity round out the 4Cs. If you need a refresher, here’s a summary of the 4Cs and how to choose the perfect diamond.

The higher the diamond is graded on any of these 4C scales, the higher the price. Just remember that you don’t need to be at the top of the scale to get a stunning, high quality diamond. For example, you may not want to shell out for a diamond graded “Flawless” because it’s like paying extra for minuscule clarity improvements that are invisible to the naked eye. Most couples prefer to drop slightly down the clarity scale to get a better value. Learn more about clarity with our helpful diamond clarity chart 

Did you know that some engagement rings are sold with fake diamonds or gemstones?

They're often called cubic zirconia or diamond simulant engagement rings, but don't be fooled into thinking that they're real diamond engagement rings or anywhere near the quality you’ll want for a lifetime. They cost much less for a reason: cubic zirconia and similar simulants lack sparkle, durability, fire, brilliance, longevity, value... they just don't compare to lab grown diamonds or mined diamonds.

These diamond imposters cost way less than the real deal, but as the old adage goes, you get what you pay for. As jewelers and people who appreciate quality, we don't recommend simulants because they don't wear well and get scratched and cloudy. Forget about passing them down to the next generation.

So what do you do if you want a real diamond, but don't want to pay upwards of $20-30k or more? It's definitely time to consider lab grown diamonds.

Lab created diamonds are real diamonds that have been created in a laboratory. They look, feel, and wear the way mined diamonds do - but are much friendlier to the planet (and your wallet). And the beauty of lab grown diamonds is that you get the same type of unique diamond found in nature, but better - lab pricing is so much more attractive that most couples go for a much higher carat weight, higher quality lab diamond. For a much better price.


Engagement rings can be made from a number of different metals, but if you want lifetime quality, there are two metals to consider: platinum and gold. We don't recommend or offer silver because it's too soft and light for a lifetime of wear. Gold and platinum are valuable precious metals suitable for wedding and engagement jewelry. With regular maintenance, they will last a lifetime and beyond. 

Precious metal pricing is determined by global metal markets. Platinum tends to be the most valuable engagement ring metal, in part because it’s so rare. It’s also hypoallergenic and is not mixed with other metals, so this pure metal is safe for wearers with sensitive skin. Platinum engagement rings are extremely durable and won't tarnish over time. The metal is notably dense, which makes platinum engagement rings slightly heavier and more durable than gold engagement rings.

A cool fact: when platinum is polished, metal never wears away, it's only pushed around a bit. So your ring won't lose weight over time with wear or maintenance.

Gold engagement rings, on the other hand, are less dense and slightly lighter than platinum, which also makes them lower priced. This is one of the reasons why gold engagement rings are so popular. Another reason is because gold can be mixed with other metals to make white and rose colored gold.

If you have a gold engagement ring with platinum prongs (a “two-toned engagement ring”), the price could be closer to the cost of a completely platinum ring. Why? Because there are labor and material costs involved in creating two-toned rings, adding to their beauty and value. 

As for silver engagement rings, they're less dense than both platinum engagement rings and gold engagement rings. This makes them less expensive, but also less durable. Diamonds can more easily pop out of silver settings, because silver prongs are so soft. Stay away from silver if you want something that doesn't tarnish, will last forever, and has higher value.


It’s true that quality is partially determined by metal type. However, there’s more to setting quality than metal selection; a high quality engagement ring will be designed for durability and beauty.

On the durability side, the ring should be crafted to width and weight tolerances to make it strong enough for a lifetime of wear. Featherweight settings may cost less in the short term, but tend to cause trouble down the road when they bend or break. 

As far as beauty goes, this is obviously a more subjective question. However, cheaply made engagement rings are usually mass-produced - and they actually look like they’ve been mass-produced. For example, the center diamond might be set in way where it doesn’t fit properly or looks clunky. Or the ring might have unintended sharp edges or boxy angles. 

A high quality ring will hold the center diamond in a setting that looks integrated with the overall ring design and fits properly and safely. Same goes for any accent diamonds: the settings should be attractive and secure, set by an expert jeweler. Inexperienced jewelers might charge less, but you could eventually pay for the cost of loose diamonds and repairs, which bring us to…


This is an important part of ring-buying that many couples forget to consider: “what happens after I buy the engagement ring and need ring maintenance?” Maintenance might involve ring sizing, polishing or cleaning, replating white gold, or checking prongs. Engagement rings and fine jewery do require care post-purchase that can add up. Depending on where you live, resizing for example can run into the hundreds of dollars.

So when you’re looking at the cost of engagement rings, check to see whether you’ll need to add a warranty package or budget for future maintenance (Plum Diamonds provides free sizing and maintenance for life).


It's true that the cost of engagement rings varies depending on where you live, especially if you're shopping in-person.

For example, engagement ring prices in New York City may be much higher than engagement ring prices in other parts of the United States. This is because New York City has a higher cost of living, and therefore jewelers may price their items accordingly.

Beware of promises of “wholesale prices,” however, as these merchants may not be trustworthy. We recommend doing your homework, working with a reputable jeweler who plans to be in business for the long haul, and questioning anything that sounds too good to be true.

The beauty of shopping online versus in-person means that outside of tax, the cost of goods can be the same regardless of where you live. You can shop engagement rings from anywhere and still receive the same level of engagement ring value.
