How Ferko's Sources, Certifies, and Crafts Its Lab-Grown Diamond Jewelry
Ferko's Fine Jewelry
There is a lot of talk around lab-grown diamonds. And once you start actually shopping, the questions get specific fast: Where does this stone come from? Who certified it? Who made this piece, and how well did they do it?
Those are exactly the right questions to ask and they're the ones we’ll address here, about how we approach every step of the process, from the stone we select to the finished piece that ships to your door.
What Lab-Grown Diamonds Actually Are
Let’s start with the question people still type into search bars: are lab-grown diamonds real?
Yes. They are.
Lab-created diamonds are real diamonds. They have the same essential chemical, physical, and optical properties as natural diamonds. The only difference is origin. One forms in the earth over billions of years. The other is grown in a controlled setting using advanced technology
That is why the conversation around lab-grown vs natural diamonds is really about where the diamond came from, not whether it is real..
So, how are lab-grown diamonds made? There are two primary methods. The first is High Pressure High Temperature, or HPHT, which recreates the intense natural conditions that form diamonds underground. The second is Chemical Vapor Deposition, or CVD, which builds a diamond layer by layer from carbon-rich gas.
Both methods produce real diamonds made of crystallized carbon.
How Ferko's Selects Its Lab-Grown Stones
At Ferko’s, selection matters long before a design reaches the bench. We look closely at cut, color, clarity, and proportions.
We look for bright E-F color, eye-clean VS clarity, and overall consistency from stone to stone. We want the diamond to look beautiful on its own, and even better once it becomes part of a finished piece.
It is not only about what is written on a grading report. It is also about how the stone looks in real life, how it performs in a setting, and how thoughtfully it was selected in the first place.
Third-Party Certification: What It Means and Why It Matters
A lab-grown diamond should look and feel beautiful. But what matters more is knowing exactly what stands behind it.
That is where lab-grown diamond certification comes in. A grading report from an independent gemological laboratory gives you a factual record of the stone’s key characteristics.
At Ferko’s, we use IGI certified diamonds. That matters for a few reasons.
- You know what you are buying because the diamond’s characteristics are documented by a third party.
- You have a clear record of important details such as cut, color, clarity, and carat weight.
- You can verify the report number independently through the certifying laboratory’s website.
- You have a stronger reference point for insurance, future service, and peace of mind.
From Stone to Finished Piece: How Ferko's Makes Its Jewelry
At Ferko’s, mastery from years of experience informs every step of a process that is done in-house, by hand, from the first design file to the final polish. We use technology where it improves precision, and we do not cut corners because details are what make a piece look and feel right.
The process moves through four stages.
Stage 1: 3D Design
Once an order is placed, the piece begins as a 3D CAD rendering. This is where structure is resolved before any metal is touched. Sizing, stone placement, prong geometry, and setting style are all worked out digitally first.
Stage 2: Casting
The digital model is printed as a wax form, then cast. The wax burns away and is replaced by 14k solid gold, which cools into the shape of the piece. After casting, the metal structure is checked for strength before setting begins. A piece that cannot properly support its stones does not move forward.
Stage 3: Stone Setting
This is where each lab-grown diamond is set by hand. Every stone is selected for the specific piece it is going into, then checked again for consistency, fit, and overall harmony within the design.
Stage 4: Final Polishing and Inspection
The last step is polishing the gold to its finished surface, followed by a full inspection. Prong tightness, gold condition, sizing, engraving or personalization, and overall finish are all reviewed before the piece ships. Nothing leaves the bench without that sign-off.
That same care carries across categories, whether we are making lab-grown diamond rings or lab-grown diamond necklaces. It matters just as much in a pair of lab-grown diamond earrings as it does in lab-grown diamond bracelets.
How Ferko’s Compares to the Broader Lab-Grown Market
Not all lab-grown diamond jewelry is made the same way. Some brands compete on scale. Some on speed. Some on price alone. We prefer a more thoughtful balance of quality, transparency, craftsmanship, and value.

What to Look For When Buying Lab-Grown Diamond Jewelry
If you want to know what to look for in lab-grown diamonds, start by asking better questions. A smart purchase has less to do with hype and more to do with what a brand is willing to explain clearly.
Ask about the certificate
- Is this diamond independently certified by a recognized gemological laboratory such as IGI or GIA?
- Can I verify the certificate number directly on the certifying body’s website?
- Is the certificate for this specific stone, or is it a general description applied to a category of stones?
Ask about production
- Is this piece made in-house or outsourced to a third-party manufacturer?
- What metal is being used, and what is the purity?
- Is the piece made to order, or is it mass-produced and pulled from stock?
Ask about the stone itself
- What are the cut, color, clarity, and carat weight of this specific diamond?
- For multi-stone pieces, how are the stones matched and graded for consistency?
- How does the brand define quality beyond the certificate itself?
Ask about policies
- What is the return window, and what condition must the piece be in?
- Does the brand offer resizing, repairs, or post-sale service?
- Is there a warranty or any guarantee of craftsmanship?
In the end, what matters is how carefully it was chosen, how honestly it was documented, and how well it was made. That is the difference between a piece that simply looks good and one that feels right every time you put it on.
