Did you know that lab grown diamonds are indistinguishable from mined diamonds to the naked eye? These stunning gems, created in a controlled laboratory environment, share the same brilliance, fire, and durability as their natural counterparts. However, with so many questions surrounding this innovative technology, it’s essential to ask the right questions to make an informed decision. Here are 10 crucial questions to ask your jeweller about lab-grown diamonds.
1. Are These Diamonds Certified?
Certification is the foundation of trust when buying any diamond, lab-grown or natural. A certified diamond has been evaluated by a reputable gemological institute, such as the GIA (Gemological Institute of America) or IGI (International Gemological Institute). These certifications detail the diamond’s cut, clarity, colour, and carat weight, ensuring you know exactly what you’re paying for.
Jewellers should willingly provide this documentation. If they hesitate or claim it’s unnecessary, that’s a red flag.

Certification is a non-negotiable step for buyers who value quality and peace of mind.
2. What Is the Difference Between Lab-Grown and Natural Diamonds?
At first glance, lab-grown and natural diamonds might look identical—they share the same chemical composition and physical properties. However, their origins and some key factors set them apart. Natural diamonds have been formed deep within the Earth’s mantle for billions of years. They’re extracted through mining processes.
Lab-grown diamonds, on the other hand, are created in controlled environments using advanced technology. This process mimics natural diamond formation but takes weeks instead of millennia. For a deeper look at these differences, Diamonds On Richmond or a similar expert offers a helpful resource that breaks down the pros and cons of both options.
3. How Are These Diamonds Made?
Lab-grown diamonds are produced using two main methods. These techniques replicate the earth’s natural diamond-forming process but in a controlled laboratory environment.
High-Pressure High Temperature (HPHT)
This method starts with a tiny diamond seed placed under intense heat and pressure—conditions similar to those found deep within the Earth. Over time, carbon atoms attach to the seed, growing it into a larger diamond crystal.
Chemical Vapor Deposition (CVD)
A diamond fragment is introduced into a vacuum chamber filled with carbon-rich gases. As the gases heat, carbon atoms are compelled to attach to the fragment, forming a larger diamond crystal over time.
Both methods produce diamonds that are chemically, physically, and optically identical to natural diamonds. Understanding these processes can provide buyers with peace of mind and confidence in the diamond’s origins.
4. Are They Ethically and Environmentally Friendly?
Unlike mined diamonds, which can have significant ecological impacts due to deforestation, habitat destruction, and energy-intensive extraction processes, lab-grown diamonds are created in controlled settings that leave a smaller footprint.
On the ethical side, lab-grown diamonds bypass the concerns of unfair labour practices and the potential for conflict diamonds—stones mined in war zones and sold to finance armed conflicts. This makes them appealing to socially conscious buyers who want to ensure their purchase aligns with their values. That said, it’s important to note that lab-grown diamonds still require energy, particularly during production. Some manufacturers address this using renewable energy sources, reducing their environmental impact.
5. What Is the Price Difference Between Lab-Grown and Natural Diamonds?
On average, lab-grown diamonds cost 30-50% less than natural diamonds of similar size and quality. This price difference can make a significant impact, especially for buyers working within a budget or looking to maximize value. A one-carat natural diamond might be priced at around USD$6,000, while a lab-grown diamond of the same specifications could cost approximately USD$3,000 to USD$4,000.
It’s worth noting that while lab-grown diamonds are more affordable, their resale value is typically lower than that of natural diamonds. However, this isn’t a concern for many buyers since diamonds are often cherished for their sentimental value rather than as financial investments.
6. Can Lab-Grown Diamonds Be Customised?
Yes, lab-grown diamonds offer excellent flexibility for customisation. Whether you’re looking for a unique engagement ring, wedding band, or a special piece of jewellery, lab-grown diamonds can be cut and shaped to meet your preferences. This makes them a fantastic option for buyers who want something truly personal.
Discuss your ideas when working with a jeweller Customizing a piece of jewellery with lab-grown diamonds doesn’t compromise on quality or durability, ensuring your design is as timeless as it is unique.
7. Do They Require Special Care?
Lab-grown diamonds are as durable as natural diamonds and require minimal maintenance. To keep your lab-grown diamond looking its best, clean it regularly using a gentle solution of warm water and mild dish soap. Soak the diamond for a few minutes, then use a soft toothbrush to remove any buildup. Rinse thoroughly and dry with a lint-free cloth. For deeper cleaning, visit a jeweller for professional ultrasonic cleaning. Avoid exposing your diamond to harsh chemicals or abrasive materials, which can damage the metal setting.
8. Are There Any Limitations for Lab-Grown Diamonds in Jewellery?
Lab-grown diamonds are highly versatile and suitable for most types of jewellery, including engagement rings, wedding bands, earrings, and necklaces. However, there are a few considerations to keep in mind:
- Resale value: Lab-grown diamonds typically have a lower resale value, which makes them less appealing to those who view diamonds as an investment.
- Availability: Some jewellers may have limited stock or customization options for lab-grown diamonds compared to natural ones. If you have a specific design, it’s worth discussing availability and production timelines with your jeweller.
Despite these minor limitations, lab-grown diamonds are excellent for creating stunning, ethical, and affordable jewellery.
9. Can Lab-Grown Diamonds Be Insured?
Yes, lab-grown diamonds can be insured just like natural diamonds. Most insurance companies offer policies that cover loss, theft, or damage for all types of diamonds, regardless of how they were created. Insurance policies typically cost a small percentage of the diamond’s value annually. Insuring a USD$4,000 lab-grown diamond might cost around $40 to $80 annually, depending on the insurer and the level of coverage chosen.
10. What Warranties or Guarantees Come With the Purchase?
Warranties and guarantees typically cover manufacturing defects, such as issues with the diamond’s setting or workmanship, ensuring that your purchase meets quality standards. Some jewellers also offer lifetime guarantees that include free maintenance services like prong tightening, cleaning, or resizing. Others may provide replacement options if the diamond is damaged under specific circumstances.
Lab-grown diamonds represent an exciting shift in fine jewellery, offering innovation, affordability, and ethical appeal. They empower buyers to prioritize values without sacrificing beauty or quality. Take the time to explore your options and partner with a jeweller who shares your vision—your perfect piece is closer than you think.
