Best Places to Buy Custom Lab Diamond Rings

Creating a custom lab diamond ring is an exciting experience, especially when you're not only designing something unique but also creating a piece that represents you, your style, and your preferences. This is especially true when you're designing engagement rings, where every detail matters.

However, once you start looking into where to get a custom lab-grown diamond ring, things can become more complicated than they initially seem. From choosing a quality lab diamond and selecting a setting to deciding on metals and comparing quality, you're suddenly faced with a series of important decisions.

When you're creating a custom ring, where you choose to buy becomes more than just finding a place that offers options. If you're looking for a place that makes the experience enjoyable, smooth, and transparent, Rare Carat is one of the best places to buy custom lab diamond rings.

Let's take a look at some of the things that make us a trusted choice when it comes to custom lab diamond rings.

1. Lab vs. Natural Diamond Rings: Making the Choice Easy

One of the first decisions that one has to take into consideration when looking for a custom-made diamond ring is whether one should go for a natural diamond or a lab-created one. Even though both of these stones have the same level of brilliance and beauty, the different price ranges of these stones sometimes cause buyers to look for lab-created diamonds.

Lab-grown diamonds possess the same physical, chemical, and optical properties as natural diamonds. The only major difference worth mentioning is in their production process. Since lab-grown stones are produced artificially, they are more readily available in terms of price points while maintaining the same level of sparkle as a natural stone.

This is, in fact, one of the key reasons why many people prefer lab diamonds while planning a custom ring. The flexibility in the prices helps them to choose bigger stones, better quality, and even a custom design within their budgets.

Check out the price difference between both types of diamonds (with the same 4Cs specifications) to have a better understanding of the cost savings that lab diamonds offer:

Disclaimer: Diamond prices may vary depending on factors such as cut, color, clarity, certification, and market conditions.

At Rare Carat, we make this decision easier from the very beginning. You can choose lab-grown diamonds right from the start of your search, allowing you to focus only on options that match your preferences.

You can also compare lab and natural diamonds using our advanced diamond search filters. This helps to identify the differences in prices, sizes, and quality based on the same 4Cs, which will help you progress with your custom design in a confident manner.

2. All The Popular Diamond Shapes For Customization

The next step after you've made up your mind to go with a lab-grown diamond is choosing a diamond shape that suits you best. The diamond shape is a significant factor in defining the look of your custom ring. The shape affects not only the brilliance of the diamond but also its size.

While some people might be comfortable with a conventional shape, others might be looking for something unique. When designing a custom ring, choosing a shape early is advisable, as it can help you determine other factors, such as style.

Check out some of the popular lab-created diamond shapes available for seamless customization:

• Round
• Asscher
• Heart
• Marquise
• Oval
• Radiant
• Cushion
• Pear
• Princess
• Emerald

3. All Popular Carat Sizes For The Best Customized Diamond Ring

After you have decided on your preferred shape of a diamond ring, you then have to make a decision on the carat size of your ring. The carat weight is one factor that significantly contributes to the appearance of your custom ring.

One of the biggest benefits associated with lab-grown diamonds is the flexibility it provides in choosing the right carat weight without having to break the bank to purchase a diamond ring. Lab-grown diamonds are affordable compared to natural diamonds.

Some people want to wear something simple and elegant with smaller carat sizes, while others want to wear something visible with larger carat sizes. As you are designing your own ring, choosing the right carat size is important to help you with the other design choices.

4. Certified Lab Diamonds with Two-Step Verification

Before moving into customization, shape, or carat size, one thing most Rare Carat buyers don’t have to worry about is diamond quality. That’s because every mined and lab diamond available on Rare Carat is certified and carefully reviewed before it becomes part of your custom ring.

So, all of our lab-grown diamonds are backed by valid reports from the best gemological labs (GIA, IGI, or GCAL) in the industry. This ensures that you're purchasing a lab-grown diamond with clearly defined cut, color, clarity, and carat weight, which will give you a proper idea of what exactly you are purchasing.

Moreover, Rare Carat also provides an additional two-step verification process.

In the first phase, the laser inscription of the diamond will be examined through a 60x to 110x professional grade magnification. If anything fails to meet our standards, we will then send the diamond back to the source to make the necessary corrections. It will then be re-examined once it reaches us, and only then will we make it available to our customers if we find that the inscription matches and is visible.

The second phase of the two-step verification process includes tests to ensure the authenticity of the diamond, which will be conducted by professional-grade UV fluorescence machines. This will give us the full picture and ensure that the claims made in the certificate of the diamond are indeed true.

We take extra care in this second phase. If our customers choose to purchase a rare diamond, we then make use of the Yehuda machine to test the diamond or send it to GIA New York.

No matter what, you can choose the diamond for personalization with peace of mind, as it will be of the highest quality regardless.

5. All Popular Setting Styles To Reflect Your Style

This is where everything starts to come together.

You can take the same diamond, and it can look completely different depending on the setting. It can be simple and traditional, or it can add even more sparkle and design to your ring to really make it stand out.

It’s not about choosing the most intricate setting. It’s about choosing what feels right after choosing your diamond shape and size.

At Rare Carat, you’ll find many setting styles to make customization easy. Here are some of the most popular styles you can choose from:

You can explore these popular setting styles below:

• Solitaire Ring Setting
• Halo Ring Setting
• Pavé Ring Setting
• Three-Stone Ring Setting
• Hidden Halo Ring Setting
• Cathedral Ring Setting
• Bezel Ring Setting
• Vintage-Inspired Ring Setting
• Diamond with Gemstones Ring Setting
• Unique Ring Setting

Once you've selected your preferred setting style, you can move forward with the remaining customization details to bring your custom lab diamond ring to life.

6. Popular Setting Metal Options for Proper Personalization

Once you've selected the setting style, the next step is choosing the metal. While the metal doesn’t change the diamond itself, it can completely change how the diamond is perceived.

White gold and platinum have a crisp and modern look. The yellow gold color is traditional and classical because of its golden color. The rose gold color provides a subtle contrast that is noticeable but not too bold. The slightest color variation will greatly affect the overall look of your custom-made ring.

8. Popular Diamond Ring Styles For A Little Inspiration

One of the easiest ways to bring your own flair to any ring is by changing the diamond shape to one that feels like you and your aesthetics. Take this bestselling three-stone stunner, for example.
