Where Are the Best Diamond Stores?

Diamonds are some of the most beautiful items on earth. Whether it's from the highly volcanic journey with the pressure to create them, the effort gone into mining them, or the skill that goes into cutting them into gorgeous faceted designs, there's something about diamonds that sets them apart from other gemstones. Choosing a diamond can be something special.

You might be looking for a gemstone to set into an engagement ring (congrats on popping the question), or maybe you're just looking for a piece that will stand out: a diamond necklace or a pair of earrings will turn heads like nothing else. No matter your need, finding a trustworthy store to get your diamonds or diamond jewelry is a must.

Selecting the right diamond store can be a lot like finding the right jewelry piece. You want to pick a store that's a perfect fit for you, specifically.

Whether you're looking for a round, oval, cushion, emerald, or princess cut diamond, your chosen diamond store should have every glittering gemstone your heart desires.

But overall, it's easier than ever to get diamonds or other fine jewelry from a diamond store right from the comfort of your home.

Online diamond shopping is so modern these days that you feel like you're almost in the store. Diamonds, rings, necklaces, and all sorts of other jewelry items are displayed in 3D and rotating images (sometimes even full videos) to show you every angle of the diamond you might want to buy. Plus, you'll get access to more exclusive stones since you'll be able to see the entire diamond store inventory rather than the pieces and loose stones that are on offer at a specific brick-and-mortar location. With other benefits like price match guarantees, wholesale prices, and lifetime guarantees, online diamond stores promise you the pinnacle experience for jewelry buying (so, you can make your special moments, gifts, and celebrations even better).

If you're searching for that perfect fit and need the top diamond store out there to meet your needs, we get it.

Diamond Store FAQ

What is a diamond?
One of the most sought-after gemstones in the world, diamonds are one of the hardest substances known to man. Diamonds form from carbon under high pressure and temperature.
Why are diamonds so popular?
Fun backstory: diamonds weren't commonly used in engagement rings until 1947, when the British mining company De Beers featured them in an advertising campaign! The rest, as they say, is history. Diamonds now represent financial success, long-term commitment, and status.
What are the "4Cs" when shopping for a diamond?
Cut, carat, color, clarity. Cut is the only human "influence" on a gemstone: round, princess, cushion, marquise and oval are some of the more common shapes given to diamonds. Carat represents the weight of the diamond, with 1 carat equal to 200 milligrams. Color evaluates the stone using letters of the alphabet; the closer to "A", the whiter the stone, though most people find stones in the G-H rating to still be icy-white in appearance. Clarity is a little more difficult for the average consumer to see, especially without magnification: the categories measure inclusions, or irregularities that happen during the formation of the diamonds but are hard to see without magnification, as well as blemishes like scratches or chips.
What's the difference between natural and lab-created diamonds?
The names say it all: natural diamonds come from the earth, while lab-created or synthetic diamonds come from scientists! But, other than their origins, these two types of diamonds are exactly the same chemically and optically: even expert gemologists have a hard time telling them apart without using a jeweler's loupe! And, as you might imagine, synthetic diamonds are usually much more affordable.
What are GIA, AGS, EGL and IGI?
These acronyms all refer to gemological societies and institutes with diamond grading scales used throughout the industry: Gemological Institute of America, American Gemological Society, European Gemological Laboratory, and International Gemological Institute. Generally speaking, GIA and AGS are seen as the most accurate and scientific, so if you're buying a higher-priced stone you may want to ensure that it's been graded by one (or both!) of those two systems.
Why would I buy a loose diamond instead of an already-made engagement ring or other piece of jewelry?
If you're looking for a one-of-a-kind piece, you're not going to find it by buying the first pretty ring or solitaires you see at your local jewelry store. Many customers want something with a story that can be handed down as an heirloom: the shape of the stone chosen to match her eyes, the setting selected to complement his personality, and so on. Buying loose diamonds is the first step in a truly unique piece of jewelry.
Are diamonds a good investment?
While you'll find no shortage of companies wanting to sell you diamonds as an investment, most experts say that the average consumer isn't likely to profit from them. Unless you're buying extremely large diamonds (e.g. 20 carats or more) or ones with a noteworthy history (like being owned by a celebrity), you may have a hard time selling the diamonds you buy for more than you paid. If you're planning on spending a significant amount of money for a diamond, do it because you appreciate the beauty or want to own (or give) something precious - but save your investments for more reliable means of generating profits!
Is it safe to buy loose diamonds online?
Absolutely. Of course, you shouldn't buy a diamond from an online retailer without doing your research: choose a business with a well-established history, preferably with a high rating from the BBB, and be sure that the diamond you buy has been rated and certified by one of the independent institutes or laboratories mentioned above. You can rest assured that the diamond retailer will take every measure to get your stone delivered safely, including tracking and insurance.

What are the benefits of buying loose diamonds?

When many people think about diamonds, buying diamond jewelry from a local store immediately comes to mind. However, buying loose diamonds is an option as well. At first glance, it may seem easier to simply walk into a jewelry store and buy a diamond ring or necklace, but the reality is that there are several exciting benefits associated with buying loose diamonds. In fact, with a closer look at the benefits of buying loose diamonds, you may decide that this is the best option for you. What can you expect when you buy loose diamonds?

Online Research

When people initially start shopping for a diamond, they focus on carat weight. While this is an important factor to consider, there are other factors that impact a diamond's true value. In addition to the carat weight, the stone's cut, clarity, and color play a role. These are referred to as the 4Cs of diamonds, and they are reviewed during the diamond certification process. One of the easiest ways to buy loose diamonds is online, and you can conveniently complete online research on all of these important factors before you make your purchase. Some diamonds used in preset jewelry are not certified, so you may not be able to determine the true value of that jewelry.

Not all loose diamonds are certified, but some sources exclusively sell certified diamonds. These are diamonds have been analyzed by a reputable lab, such as GIA, EGL, AGS or a few others. Through the certification process, a diamond's characteristics are mapped. This includes its flaws, dimensions and other key features. In fact, the certification process covers the 4Cs of diamonds. The lab certification report for a specific certified diamond is usually readily available for you to view online when you buy loose diamonds, and this makes it easy for you to understand fully what you are buying before you finalize your purchase. Many jewelry retailers, however, may not provide the certification documents to you unless you specifically request them.

Be aware, however, that you should not assume that the gemstone that you purchase online is the same diamond that you will receive in the mail. You should always obtain an appraisal from a certified professional as soon as you receive your loose diamonds. This holds true if you buy a diamond in a setting. The good news is that it is much easier for an appraiser to inspect and appraise loose diamonds versus those that are in a setting.

Comparison Shopping

Are you concerned about overpaying for diamonds or diamond jewelry? Because of the wealth of online information that is available on certified diamonds for sale, it is easy to comparison shop for the best value within your price range regardless of whether you buy a loose stone or a diamond in a setting.

However, when you purchase a diamond in a setting, there may be a question about how the setting's design and materials impact the total cost of the jewelry. When you purchase a loose diamond that is certified, on the other hand, you will know exactly how much that specific diamond is worth. This gives you some control over both value and cost. Whether you intend to hold loose gemstones or to place a diamond in a setting at a later date, the ability to easily comparison shop will help you to avoid overpaying.

A Financial Investment

The value of both loose diamonds and diamond jewelry will fluctuate over time, but you can expect them to share an upward trajectory over a long period of time. You may assume that loose diamonds will hold their value just as well as diamond jewelry would, but this is not always the case. In fact, loose diamonds generally hold their value better than diamonds that are set in earrings, necklaces, earrings and other settings. This is particularly true when you purchase certified loose diamonds.

Why is this the case? Some of the diamonds used in earrings, necklaces and other pieces have not been certified, so you cannot truly know the value of the gemstones when you buy these prepared pieces. This means that you also cannot truly determine the value of the jewelry, and you risk the possibility of paying more than the item is actually worth. When you buy a certified loose diamond, on the other hand, you will have a record of its value before it is placed in a setting. You will be less likely to overpay for that piece of jewelry, and the value of that jewelry will be partially secured by the diamond certification paperwork.

Keep in mind that many people purchase loose diamonds to hold securely for a period of time. For example, they may store diamonds in a bank's security deposit box or in a locked safe in their own home. The value of diamonds has maintained an upward path over the years, so this could be a smart way for an investor to diversify his or her portfolio.

Access to a Large Selection

Generally, when you shop for diamond jewelry at a local store, you are purchasing the stone and the setting together. You do not usually have the option to change out the diamond. However, the ability to select the specific diamond for your setting gives you greater control over the quality of the finished piece as well as its cost and value. More than that, with the ability to mix and match diamonds and settings, you have access to a greater overall range of possibilities.

Are you wondering how significant this benefit is? A single diamond wholesaler may offer hundreds or even thousands of certified loose diamonds at any given time. With multiple reputable wholesalers available for you to shop with, you will have a huge selection to choose from when you shop for loose diamonds. Some online wholesalers offer a convenient search function so that you can easily narrow down the options specifically to those that meet your requirements for cost and price.

Your Choice of Settings

While many people choose to keep loose diamonds as a financial investment, others shop for a loose diamond with a more specific purpose in mind. For example, you may want to select the exact diamond that will be placed in a custom-made engagement ring or necklace. When you buy a loose diamond for this purpose, the possibilities are endless. A private jeweler may have some predesigned settings for you to choose from, and your selection of a specific diamond for that setting ensures that the jewelry is tailored to your budget and expectations.

Another exciting option is to work with a private jeweler to create a one-of-a-kind piece. Everything from the jewelry's metal and size to its style will be created to your exact specifications. In comparison, if you choose to buy a diamond that is already in a setting, you are truly limited to the possibilities available from that store at the time of your visit.

Diamonds are often used in jewelry that has special meaning, such as a wedding ring, an engagement ring, an anniversary ring and more. These are important pieces that you understandably want to be perfect for the individual and for the occasion. With this in mind, the ability to choose both the loose diamond and the setting is a true benefit.

Get to Know the Possibilities Today

Before you settle for diamond jewelry purchased from a retail store, you owe it to yourself to explore the exciting possibilities available to you with the purchase of loose diamonds. With gemstones available at a wide range of prices and qualities, you could potentially find exactly what you are looking for when you shop for a loose diamond today.
