Also known as laboratory-created or man-made diamonds, lab-grown diamonds are gems created by people. They are grown in a laboratory, using high-tech processes that recreate the conditions under which diamonds form naturally.
In terms of quality and appearance, it is almost impossible to tell a lab-grown diamond from a natural diamond with the naked eye. The main difference lies in their origin, and they are a great alternative to natural diamonds.
To keep their sparkle and beauty, lab-grown diamond jewelry needs regular care. Like all fine jewelry, it can build up dirt, oils and chemical residue, which can dull its brilliance. So how should you care for and clean lab-grown diamond jewelry? In this article, we share best practices for keeping it in perfect condition without risking damage.
Understanding the characteristics of lab-grown diamonds
How lab-grown diamonds are created
Lab-grown diamonds are created using two main methods that mimic the natural conditions in which diamonds form:
-
The HPHT (high pressure, high temperature) technique: this is the closest to the natural process that takes place deep in the earth. It involves subjecting graphite to intense pressure and heat.
-
And the CVD (chemical vapor deposition) technique: it produces lab-grown diamonds with even fewer flaws. It involves treating a diamond seed with natural gas in a low-pressure chamber, under a microwave beam.
It takes about a month to create a three-carat lab-grown diamond, and roughly a month to produce a one-carat gem.
The physical and chemical properties of lab-grown diamonds
Lab-grown diamonds have the same physical and chemical properties as natural diamonds. They are made of pure carbon and have a hardness of 10 on the Mohs scale (the highest). This gemstone is therefore considered the hardest natural material. Lab-grown diamonds cleave perfectly and are just as brittle as natural diamonds.
Finally, their dispersion index is 0.044, while their refractive index is 2.42. These figures refer, respectively, to the fire and the brilliance of the gem. Lab-grown diamond jewelry is every bit as stunning as natural diamond jewelry.

Factors that can affect the durability and sparkle of lab-grown diamonds
Exposure to harsh chemicals, scratches, knocks or improper handling can affect the sparkle and durability of your lab-grown diamond jewelry. Sweat, dirt, makeup, dust, household cleaners, hairspray and hand lotion can also build up on the gem over time, dulling its brilliance.
Regular cleaning and care will help you preserve their beauty for as long as possible. Also, remember to store your lab-grown diamond jewelry properly when you're not wearing it.

Storing lab-grown diamond jewelry properly
To prevent scratches and knocks, each piece of lab-grown diamond jewelry should be stored individually in a soft fabric pouch or a separate jewelry box. Then keep your jewelry boxes in a dry, cool and safe place, because humidity can also tarnish metals.
Avoiding exposure to harsh chemicals
Chemicals such as chlorine, detergents and beauty products can dull the sparkle of lab-grown diamonds. We therefore recommend taking off your jewelry before washing dishes, cleaning, swimming, applying makeup, gardening, doing DIY projects or any other exposure to harsh chemicals.
Avoiding physical damage (knocks, scratches)
Even though lab-grown diamonds are extremely hard, they can be chipped or scratched by a hard blow. So avoid wearing your jewelry during strenuous physical activity. Take it off as well when using power tools for DIY projects, for example.
Cleaning lab-grown diamond jewelry
Recommended cleaning frequency
We recommend cleaning your lab-grown diamond jewelry at home every one to two weeks. But since this gemstone isn't affected by water, you can clean your pieces as soon as you notice them starting to lose their sparkle, without waiting a week.
At-home cleaning methods
The first method is to soak your jewelry for about 30 minutes in a bowl of lukewarm or warm water with dish soap. Then use a soft-bristled toothbrush to brush the gem. A children's toothbrush is best, because it's softer. Keep this brush just for the regular cleaning of your lab-grown diamond jewelry.
You can also clean your jewelry by soaking it in a mixture of water and ammonia (6 parts water to 1 part ammonia). Leave it in for 30 minutes before following the steps of the first method.
The last method is to soak your lab-grown diamond jewelry in a glass of vodka for a few minutes.
For all 3 methods, rinse your jewelry under warm running water after cleaning. Then dry it with a soft linen or cotton cloth.
Using a soft cloth for polishing
After cleaning, rinsing and drying, rub your jewelry with a polishing cloth to make the metal and the stone shine.
When and why to see a professional for cleaning
Before cleaning, take a close look at your lab-grown diamond jewelry. Are the diamonds moving in their settings? Are the prongs secure? If you notice a problem, take your piece to a jeweler for cleaning without risk of damage.
If your jewelry also has delicate inlays, or if you don't feel comfortable cleaning it yourself, it's best to call on a professional. An annual professional cleaning is also recommended for optimal care.
Repairs and professional care
If you notice deep scratches, loose stones or other damage to your jewelry, it's best to see a professional for repairs.
The repair process may involve tightening the gemstones, polishing out scratches or replacing damaged diamonds. A qualified jeweler can assess the condition of your jewelry and recommend the best repair options.
The cost of professional care depends on the condition of your jewelry and the complexity of the repairs needed. It's always a good idea to get a quote before any work begins.
Insurance and warranty for lab-grown diamond jewelry
Previous Next
As with any valuable investment, it's wise to insure your lab-grown diamond jewelry. Insurance can protect you against theft, loss or damage resulting from an incident. Homeowner's or renter's insurance is generally the best fit for this kind of coverage. Some insurers offer a "theft by assault" option to protect your jewelry while it is being withdrawn from, deposited at or transported to a bank.
There are several types of jewelry coverage, including coverage for repairs, replacement at new value and replacement at depreciated value. Talk to your insurer to understand which type of coverage best suits your needs. Note, however, that you cannot be covered for wear and deterioration of your jewelry, which is why regular care is so important.
If your lab-grown diamond jewelry is stolen, in France you have 24 hours to file a police report. Then send the list of stolen jewelry to your insurer within 2 business days. The process may involve assessing any damage to your jewelry if it is recovered, proving ownership, and confirming its value if it is damaged or not recovered.
In conclusion
Caring for lab-grown diamond jewelry involves proper storage, regular cleaning and preventing damage. It's important to see a professional for annual cleanings and repairs.
In short, regular care is essential to maintaining the sparkle and beauty of your lab-grown diamond jewelry. With proper care, these precious pieces can last a lifetime and be passed down from generation to generation.
