Create Your Own Custom Lab-Grown Diamond: A Diamond Made to Your Requirements

Finding the right diamond is not always about choosing from what is already available. Sometimes, you already know exactly what you want—a particular shape, carat weight, color, clarity or overall appearance.

That is where a custom lab-grown diamond service can make the experience different.

At Cherish Diams, we help customers turn specific diamond requirements into a personalized sourcing and creation experience. Instead of limiting your choice to available stones, you can share your requirements and explore a lab-grown diamond created or sourced according to your specifications.

Your Diamond. Your Requirements.

Every buyer has a different idea of the perfect diamond.

You may be looking for a specific:

Diamond shape
Carat weight
Color
Clarity
Cut
Proportions
Certification requirement
Fancy color
Overall appearance

Rather than compromising on the details, a custom diamond service allows you to communicate what you actually want.

The goal is simple: help you find a diamond that matches your requirements.

What Is a Custom Lab-Grown Diamond?

A custom lab-grown diamond is a diamond selected or produced according to specific customer requirements rather than simply choosing from a standard available inventory.

Depending on your requirements, you can specify important characteristics such as the diamond's shape, carat, color and clarity.

For buyers who have a particular diamond in mind, this approach can make the search more focused and personalized.

Choose Your Diamond Shape

Shape is one of the first details to consider when creating your custom diamond requirement.

You can request popular shapes such as:

Round – Classic and highly versatile.

Oval – Elegant with an elongated appearance.

Pear – Distinctive with a graceful pointed end.

Emerald – Sophisticated with clean step-cut facets.

Radiant – Brilliant and contemporary.

Cushion – Soft, romantic and classic.

Marquise – Elongated and distinctive.

You can also discuss other specialized or modified diamond shapes depending on your requirement.

Choose Your Carat Weight

Whether you are looking for a smaller diamond for a delicate design or a larger stone with strong visual presence, carat weight is an important part of the specification.

You can share your preferred carat range rather than searching through diamonds that do not match your requirements.

For example, your requirement could be:

2.00–2.20 CT | Oval | F Color | VS1 Clarity

This gives the diamond search a clear direction from the beginning.

Select Your Color & Clarity

Color and clarity can significantly influence a diamond's appearance.

You may have a preference for a bright, near-colorless diamond or a specific clarity range based on your needs.

For example, you could request:

D–F color
G–H color
VS1–VS2 clarity
VVS clarity

Your requirements can be adjusted depending on your desired appearance and budget.

Cut & Proportions Matter

Two diamonds with the same shape and carat weight can look different because of their proportions and cut characteristics.

For this reason, a custom diamond search should not focus only on carat.

Depending on the shape, factors such as proportions, symmetry and overall cut quality can help determine how the diamond looks and performs.

At Cherish Diams, your requirements can be discussed in detail so the search focuses on the complete diamond specification rather than just one number.

What Makes the Cherish Diams Custom Diamond Service Different?

Our approach is built around your requirement first.

Instead of simply asking you to choose from a fixed list, you can tell us what you are looking for.

You can share:

“I need a 3 CT radiant lab-grown diamond, F color, VS1 clarity.”

Or perhaps your requirement is more specific:

“I want a 1.50 CT pear diamond with excellent proportions and a clean appearance.”

We can use your specifications as the starting point for finding the right diamond options.

From Your Requirement to Your Diamond

The custom diamond journey can be simple:

1. Share Your Requirement

Tell us the shape, carat, color, clarity and other specifications you need.

2. Discuss Your Preferences

If you are unsure about certain specifications, you can discuss your priorities and budget.

3. Explore Suitable Options

We help identify diamond options that match your requested specifications as closely as possible.

4. Review the Diamond Details

You can review the relevant diamond characteristics and certification information when applicable.

5. Select Your Diamond

Once you find the diamond that meets your requirements, you can move forward with your chosen stone.

Custom Diamonds for Different Needs

A custom lab-grown diamond can be useful for many types of buyers.

Engagement Diamonds

Looking for a particular center stone for an engagement ring? Start with the diamond specifications you want.

Special Gifts

A specific diamond shape or size can make a gift more personal.

Unique Diamond Requirements

If you are searching for an unusual shape, specific carat range or particular color and clarity combination, a custom search can give you more flexibility.

Jewelry Manufacturers & Designers

Jewelry professionals may also require diamonds with specific specifications for their designs and production requirements.

You Don't Always Need to Know Everything

Not sure whether you need VS1 or VS2? Unsure between oval and pear? Don't know what carat size will work best?

That's okay.

A custom diamond service is not only about giving us a list of specifications. It is also about helping you understand your options so you can make a more informed decision.

You can start with what you know—such as your preferred shape and approximate carat—and refine the other details from there.

Create Your Diamond Requirement

The best part of a custom diamond experience is that you start with your idea.

Instead of saying:

“Show me what you have.”

You can say:

“This is the diamond I am looking for.”

That difference gives your diamond search a much more personalized direction.
