Lab grown diamond necklaces have become a popular choice for people who want genuine diamond jewelry at a more accessible price. These necklaces feature real diamonds that share the same physical, chemical, and optical properties as mined diamonds. The main difference lies in how the diamonds are created. Modern technology produces these gemstones in controlled laboratory environments rather than extracting them from the earth.
This guide explains how lab grown diamonds are made, how they compare with natural diamonds, and what to consider before buying a necklace.

What Are Lab Created Diamonds?
Lab created diamonds are genuine diamonds formed by replicating the natural conditions that create diamonds beneath the Earth’s surface. Manufacturers typically use one of two methods.
The High Pressure High Temperature, or HPHT, process recreates the intense heat and pressure found deep underground. The Chemical Vapor Deposition, or CVD, method grows a diamond crystal layer by layer from carbon-rich gases.
Both methods produce diamonds with the same crystal structure as natural diamonds. Professional gemological laboratories can identify their origin using specialized equipment. To the naked eye, they appear identical.
Why Lab Grown Diamond Necklaces Are Becoming Popular
One of the biggest reasons buyers choose lab grown diamond necklaces is value. Since laboratory production avoids mining costs, these diamonds usually sell for significantly less than comparable natural diamonds.
Many buyers use the savings to purchase a larger center stone or a higher quality diamond. Others simply enjoy owning genuine diamond jewelry while staying within their budget.
The lower cost does not mean lower quality. Certified lab grown diamonds are graded using the same standards applied to natural diamonds.
Lab Grown Diamonds vs Natural Diamonds
Many shoppers compare lab grown diamonds vs natural diamonds before making a purchase.
Natural diamonds form underground over billions of years through geological processes. Lab grown diamonds form within weeks using advanced technology.
Aside from their origin, both types have nearly identical properties.
| Feature | Lab Grown Diamonds | Natural Diamonds |
|---|---|---|
| Origin | Laboratory | Earth |
| Chemical Composition | Pure carbon | Pure carbon |
| Hardness | 10 on Mohs scale | 10 on Mohs scale |
| Appearance | Identical | Identical |
| Certification | Available | Available |
| Typical Price | Lower | Higher |
Jewelry experts evaluate both using the Four Cs.
- Cut
- Color
- Clarity
- Carat weight
These factors determine beauty and value regardless of origin.
What Is the Difference Between Lab Grown and Natural Diamonds?
People often ask, what is the difference between lab grown and natural diamonds?
The biggest difference is origin.
Natural diamonds developed naturally beneath the Earth’s surface over an extremely long period. Lab grown diamonds are produced in laboratories using advanced equipment that recreates those conditions.
Another difference is rarity. Natural diamonds have limited geological supply. Lab grown diamonds can be produced according to market demand.
Resale value may also differ. Natural diamonds have traditionally retained stronger resale demand, although resale prices vary widely for all diamonds based on quality, market conditions, and certification.
In terms of sparkle, hardness, durability, and everyday wear, both perform the same.
Are Lab Grown Diamonds Cheaper?
A common question is, are lab grown diamonds cheaper?
Yes. In most cases, lab grown diamonds cost substantially less than natural diamonds with the same specifications.
Several factors contribute to the lower price.
- Laboratory production is more predictable.
- Mining and large-scale extraction costs are eliminated.
- Supply can increase as production technology improves.
Price differences vary by size and quality. A buyer may find a one-carat lab grown diamond priced well below an equivalent natural diamond. Exact savings depend on market conditions and the diamond’s grading report.
Choosing the Right Lab Grown Diamond Necklace
Selecting the right necklace involves more than choosing a beautiful stone.
First, review the diamond grading report. Independent certification from respected gemological laboratories provides confidence in the diamond’s quality.
Next, consider the necklace style.
Popular choices include:
- Solitaire pendants
- Halo necklaces
- Three-stone designs
- Tennis necklaces
- Station necklaces
Metal choice also affects appearance. White gold enhances colorless diamonds with a modern look. Yellow gold creates a warm contrast. Rose gold offers a softer appearance, while platinum provides excellent durability.
Chain length also matters. A shorter chain highlights the neckline, while longer chains create a layered look.
Diamond Certification Matters
Reliable certification helps buyers understand exactly what they are purchasing.
Leading gemological laboratories evaluate lab grown diamonds using grading standards similar to those for natural diamonds. A grading report includes details about cut, clarity, color, carat weight, proportions, and any treatments.
Always verify that the certificate matches the engraved identification number on the diamond if one is provided.
Caring for Lab Grown Diamond Necklaces
Lab grown diamonds require the same care as natural diamonds.
Clean the necklace with warm water, mild soap, and a soft brush. Rinse thoroughly and dry it with a lint-free cloth.
Store each necklace separately to prevent scratches on other jewelry. Although diamonds are extremely hard, they can scratch one another.
Inspect the setting regularly. Loose prongs can increase the risk of losing the diamond during daily wear.
Professional cleaning and inspection once or twice a year helps maintain both appearance and security.
Are Lab Grown Diamond Necklaces Durable?
Yes. Lab grown diamonds rank 10 on the Mohs hardness scale, just like natural diamonds.
This exceptional hardness makes them suitable for daily wear. They resist scratching under normal use and maintain their brilliance for many years.
The durability of the necklace also depends on the setting and metal quality. Strong craftsmanship protects the diamond during regular use.
Who Should Choose a Lab Grown Diamond Necklace?
Lab grown diamond necklaces appeal to many types of buyers.
Someone purchasing a first piece of diamond jewelry may appreciate the lower price without sacrificing quality.
Gift buyers often choose larger diamonds while staying within a planned budget.
People who value technological innovation also find lab created diamonds appealing because they represent a modern approach to diamond production.
The right choice depends on personal priorities, budget, and preferences rather than appearance alone.
Final Thoughts
Lab grown diamond necklaces combine genuine diamond beauty with a different production method than mined diamonds. They offer the same brilliance, hardness, and everyday durability as natural diamonds while often costing less.
Understanding lab grown diamonds vs natural diamonds helps buyers make informed decisions. Knowing what is the difference between lab grown and natural diamonds also removes common misconceptions. Since lab created diamonds are real diamonds, buyers can focus on quality, certification, design, and craftsmanship instead of assuming they are imitation stones.
Whether you prefer a classic solitaire pendant or an elaborate necklace, choosing a certified lab grown diamond allows you to select a piece that matches your style, budget, and long-term expectations.
