A lab-grown diamond is a diamond created in a controlled laboratory environment using advanced technology that replicates the conditions in which diamonds naturally form.

Rather than being mined from the earth, lab-grown diamonds are grown from a small diamond seed using one of two methods: Chemical Vapor Deposition (CVD) or High Pressure High Temperature (HPHT).

The result is the same chemical, physical, and optical properties as a natural diamond, with a different origin.

At ZM Fine Jewelry, we love lab-grown diamonds for their beauty, quality, and the flexibility they offer when creating a piece that feels truly yours.

Yes. Lab-grown diamonds are real diamonds.

They are made of crystallized carbon and have the same chemical, physical, and optical properties as natural diamonds. They offer the brilliance, sparkle, durability, and timeless beauty you expect from a diamond.

The main difference is their origin: natural diamonds form within the earth over an extremely long period of time, while lab-grown diamonds are created in a controlled laboratory environment using advanced technology.

Lab-grown diamonds should not be confused with diamond alternatives such as moissanite or cubic zirconia. While these stones can have a diamond-like appearance, they are different gemstones with different chemical and physical properties.

Choosing the right diamond is about finding the balance between beauty, quality, size, and budget that matters most to you.

A great place to start is with the 4Cs: Cut, Color, Clarity, and Carat Weight.

Cut: Influences how beautifully your diamond reflects light and sparkles.

Color: Refers to how colourless a diamond appears. The less noticeable colour, the higher the colour grade.

Clarity: Evaluates the natural characteristics and inclusions found within a diamond. Many inclusions are microscopic and cannot be seen without magnification.

Carat Weight: Measures the weight of the diamond and is one of the factors that influences its overall size and price.

Beyond the 4Cs, consider the diamond's shape, proportions, setting, and how it looks to your eye. Two diamonds with similar specifications can still have their own unique appearance.

There is no single “perfect” diamond, the right one is the diamond that gives you the look you love while staying within your priorities and budget.

On top of everything you’ve read above, we wanted to share a little more about our lab-grown diamonds and custom jewelry process.

Our lab-grown diamonds are carefully selected with quality, beauty, and value in mind. Unless otherwise specified, we focus on high-quality, colourless diamonds with excellent clarity and cut characteristics. Each diamond is individually sourced based on the specifications of your order, allowing us to find the best combination of quality and value rather than limiting you to a small selection of pre-selected stones.

Looking for a particular carat weight, shape, colour, clarity, or diamond specification that you don’t see listed on our website? Simply reach out to us. Our team can source a lab-grown diamond specifically for you and help guide you through the different options available within your preferences and budget.

Customization is also at the heart of what we do. If you don’t see the exact ring or piece of fine jewelry you have in mind, we can create it for you. From modifying one of our existing designs to creating something completely custom, our team will work with you throughout the design process to bring your vision to life.

Because each piece is made to order and many of our diamonds are individually sourced for your order, our typical production timeframe for fine jewelry is approximately 6–8 weeks. Custom designs may require additional time depending on the complexity of the piece and the approval process. Production timelines may also increase during peak seasons or due to circumstances outside of our control.

We offer cancellations up until the item is ready to ship. Once fulfilled, the items cannot be returned for a refund. In the event you would like to modify something, our team can assist in transforming your piece as needed.

To avoid any confusion or miscommunication, each client received a CAD (computer design) of the ring for their review and approval before we proceed with our work (cutting the gems and casting the ring). That way, you get to see exactly what the final ring will look like. If the product has a defect upon shipping to the client that was missed, we will repair it or offer an exchange (our discretion). These exchanges can only be done within 7 days of receiving the piece and the piece must be returned in new condition (no damage).

As gold is a malleable metal, this is the reason why we can make jewelry with it, it can be bent out of shape on impact (doesn't have to be a big impact like we might think) or due to repeat movements. As such, yearly inspections and repairs is recommended.

At that point, the jeweler will inspect all the prongs to make sure they are securing the stone in place. We offer repairs and maintenance on rings at a fee (at cost of labor/materials).

In this case, the customer is responsible to ship the ring to us, and also cover the return shipping fee, plus any repair costs. We recommend shipping return orders via a trusted and trackable service as ZM Fine Jewelry is not responsible for any lost, damaged, or stolen parcels.

Any and all damage should be covered by an independent insurance (buyer's responsibility) and is not covered by the moissanite gemstone's warranty. Repairs take about 5-6 weeks.

Each purchase of a ZM Fine Jewelry gemstone comes with a Certificate of Authenticity & Limited Lifetime Warranty card. The Warranty guarantees that the moissanite stone will maintain its optical properties for as long as you own it. This includes the stone’s clarity, color, fire, luster and brilliance.

Here are the terms of the warranty:

As we create each piece to order, please allow the following timeframes for the production. Our loose stone turnaround time is 3-4 weeks from the order date. Our jewelry turnaround time is 6-8 weeks from order date.

Please note that CAD revisions are not taken into account in this production timeframe. As such, please expect an extended production timeframe if revisions are requested by the customer. Timeframes may increase without notice during peak seasons or due to other circumstances.

In most cases, if the ring you purchased is slightly too small or large, a simple resize can be done. There are limitations to rings that require a significant increase or decrease in size, and in this scenario, remanufacturing may be necessary to maintain the structural integrity of your piece.

Clients can either ship the ring back to us for the resizing or get it done locally at a jewelry shop. In the event that a simple resize is possible, resizings costs 75 CAD (approx. 60 USD) and the client is also responsible for the shipping costs (to ship here, and then the return shipping as well).

We recommend shipping return orders via a trusted and trackable service as ZM Fine Jewelry is not responsible for any lost, damaged, or stolen parcels. Resizings requiring remanufacturing entirely will be quoted by our team. Resizings take about 5 weeks.
