When buying diamonds in Hong Kong, you may hear many different names: 培育鑽石 (lab-grown diamond), 人工鑽石 (man-made diamond), 實驗室鑽石 (laboratory diamond), 人造鑽石 (synthetic diamond), or simply Lab-Grown Diamond. Do these terms mean different things? Are they the same product? Could some of them actually refer to fake diamonds?
This article starts from the common names used in Hong Kong and clarifies what each term really means, so you can understand them correctly when shopping.
The Bottom Line First
In most jewellery sales, certificate and professional contexts:
- 培育鑽石
- 實驗室鑽石
- 人工鑽石
all refer to the same category of product — Lab-Grown Diamond: a diamond grown in a laboratory environment that has the same chemical composition and physical properties as a natural diamond.
In other words, it is not an imitation diamond; it is a real diamond with a different origin.
Common Names in Hong Kong Explained One by One
1. 培育鑽石 (Lab-Grown / Cultivated Diamond)
Currently one of the more formal and widely accepted terms in Hong Kong. The emphasis is on “cultivated / grown”, highlighting that the diamond was grown rather than mined from the earth.
This wording is relatively neutral and less likely to make people immediately think of “fake”, so many specialist stores, brands and official descriptions prefer it.
2. 實驗室鑽石 / 實驗室培育鑽石 (Laboratory Diamond / Laboratory-Grown Diamond)
The most direct equivalent of the English terms Lab-Grown Diamond or Laboratory-Grown Diamond. The meaning is clear: the production environment is a laboratory.
If you look at certificates, English product pages or international materials, you will usually see this type of wording.
3. 人工鑽石 (Man-Made Diamond)
Also very common in everyday Hong Kong conversation. For some people it simply means “made by human / artificial means”; for others the word “人工” immediately suggests something fake.
So when someone says “人工鑽石”, it is best to confirm: are they referring to a lab-grown diamond (real diamond) or to a simulant such as cubic zirconia or moissanite?
4. 人造鑽石 (Synthetic Diamond)
In technical and international contexts, “synthetic diamond” is a correct term for lab-grown diamond. In everyday Hong Kong usage, however, “人造” can also carry a negative or “fake” association for some listeners.
Therefore it is useful to clarify the context when this term appears.
What Is Not a Lab-Grown Diamond
The following are not lab-grown diamonds:
- Cubic zirconia (CZ)
- Moissanite
- Glass or other imitations
These are diamond simulants. They do not have the same chemical composition or hardness as diamond.
How to Buy with Confidence
- Look for a clear laboratory-grown statement on the certificate (GIA / IGI)
- Confirm the exact Chinese or English term the seller is using
- Ask whether the stone is a real diamond (lab-grown or natural) or a simulant
