Frequently Asked Questions
What is activity code 7120.76 and what does it cover in Dubai
Activity code 7120.76 refers to Diamond & Precious Gemstones Testing Laboratory under the ISIC classification of Technical Testing and Analysis. It is the specific licence activity code used when registering a gemstone testing business in Dubai.
The scope covers scientific analysis and grading of diamonds and precious stones including rubies, sapphires, and emeralds. Services under this code include diamond grading, natural versus synthetic stone identification, treatment detection, country of origin determination, and the issuance of grading certificates and reports.
Why is Dubai a strong location for opening a gemstone testing laboratory
Dubai's position as a global commodities trading hub gives a gemstone testing laboratory immediate access to one of the world's most active diamond and jewellery markets. The DMCC alone facilitates over USD 26 billion in annual diamond trade, creating a large and concentrated client base for independent testing services.
The UAE's strategic geography allows a single laboratory to serve clients across the GCC, South Asia, East Africa, and Europe. Additional advantages include a zero personal income tax environment and strong trade connectivity, as confirmed by the Invest in Dubai platform.
The rise of lab-grown diamonds entering mainstream markets has further increased demand for reliable differentiation testing, representing a significant commercial tailwind for new entrants.
What types of clients would a precious gemstones testing laboratory serve in Dubai
The customer base for a gemstone testing laboratory in Dubai is broad and spans multiple sectors. Primary clients include wholesale diamond traders, jewellery manufacturers, and auction houses that require certified grading reports to support transactions.
Additional clients include insurance companies needing accurate valuations, customs authorities requiring origin and treatment verification, and private collectors seeking independent certification. As lab-grown stones proliferate, retailers also increasingly require testing services to maintain consumer trust.
Should I set up a gemstone testing lab on the Dubai mainland or in a free zone
Both options are available and each has distinct advantages. Mainland Dubai, licensed through the Department of Economy and Tourism (DET), provides unrestricted access to UAE-based clients without a local agent requirement under current rules, which is valuable if your primary market is domestic traders and retailers.
Free zones such as DMCC or Meydan Free Zone offer 100% foreign ownership, simplified incorporation procedures, and in some cases sector-specific infrastructure. DMCC has a dedicated gems and jewellery cluster that makes it a natural fit for this activity. Meydan Free Zone is noted as a cost-efficient option for professional and technical service activities.
The right choice depends on your target client profile, budget, and whether you need physical proximity to the DMCC trading community.
What are the key steps involved in obtaining a licence for this laboratory activity
The process begins with choosing your jurisdiction — mainland Dubai or a free zone — based on your business model and client access needs. Once decided, you reserve a trade name through the relevant authority, ensuring it complies with UAE naming conventions.
The next step is formally registering activity code 7120.76 and confirming whether any additional activities, such as jewellery valuation or consultancy, need to be added to your licence scope. Subsequent steps involve submitting incorporation documents, meeting any capital requirements set by the chosen authority, and securing approvals from relevant regulatory bodies before commencing operations.
What services are typically offered by a diamond and gemstone testing laboratory
A licensed gemstone testing laboratory typically provides a range of scientific and advisory services. Core offerings include diamond grading across the four Cs — cut, colour, clarity, and carat weight — along with identification of whether a stone is natural or synthetic.
Laboratories also conduct treatment detection, identifying processes such as heat treatment, fracture filling, and irradiation that can affect a stone's value. Country of origin determination is another key service, particularly relevant given regulations around conflict minerals. Most laboratories also issue formal grading certificates and offer consultation services to traders, retailers, and insurers.
What is driving growth in the global gemological testing and certification market
The global gemological testing and certification sector is experiencing consistent growth driven by several converging factors. Consumer trust requirements are rising as buyers demand verified certification before purchasing high-value stones, particularly in e-commerce and auction environments.
Regulatory tightening around conflict minerals has made origin certification increasingly mandatory across supply chains. Perhaps the most significant near-term driver is the rapid proliferation of lab-grown diamonds, which has created urgent demand for reliable differentiation testing to distinguish synthetic stones from natural ones. Market research firms including IMARC Group and Mordor Intelligence both document this growth trajectory.
What are the UAE naming conventions I need to follow when registering my laboratory company
When reserving a trade name for your laboratory in Dubai, the name must comply with UAE naming conventions enforced by the relevant licensing authority. Names containing offensive terms are not permitted, nor are references to political or religious bodies.
You also cannot use a name that duplicates an existing registered company name in the UAE. It is advisable to check name availability through the relevant free zone portal or the mainland Department of Economy and Tourism name reservation system before proceeding with incorporation to avoid delays.
Open a Diamond & Precious Gemstones Testing Laboratory in Dubai
Dubai moves more diamonds and coloured gemstones than most countries will ever see. The Dubai Multi Commodities Centre (DMCC) alone handles a significant share of global rough diamond trade, and the wider UAE gems and jewellery sector contributes billions to non-oil exports annually. Behind every transaction — every parcel of rough, every polished stone, every piece of high jewellery — sits a fundamental requirement: independent, credible testing and certification.
Activity code 7120.76, Diamond & Precious Gemstones Testing Laboratory, covers exactly that. If you are considering entering this space, the commercial logic is sound and the regulatory path is navigable. Here is what you need to know.

Business Activities List
Explore Over 2,500+Why Dubai Makes Sense for This Activity
Dubai's position as a global trading hub is not incidental — it is infrastructure. The Invest in Dubai platform confirms that the UAE's strategic location, zero personal income tax environment, and trade connectivity make it a preferred base for commodity-adjacent professional services. A gemstone testing laboratory here can serve clients across the GCC, South Asia, East Africa, and Europe from a single location.
The DMCC free zone in particular has a dedicated gems and jewellery cluster, making it a natural fit for this activity. However, mainland Dubai under the Department of Economy and Tourism also permits this activity, giving you flexibility on structure and client access.
Step-by-Step Licence Setup Guide
Step 1: Choose Your Jurisdiction
Decide between mainland Dubai (DED-licensed) and a free zone such as DMCC or Meydan Free Zone. Mainland gives you unrestricted access to UAE-based clients without a local agent requirement under current rules. Free zones offer 100% foreign ownership, simplified incorporation, and in some cases sector-specific infrastructure. Meydan Free Zone is a cost-efficient option for professional and technical service activities.

Register activity code 7120.76 specifically. If you intend to also offer jewellery valuation or consultancy, confirm whether these require separate activity codes. Bundling incompatible activities on a single licence can cause compliance issues later.
Step 4: Secure Initial Approval
Submit your application with passport copies, proposed business plan, and any professional qualification documents. For a testing laboratory, authorities may request evidence of technical competence — gemological certifications from GIA, Gübelin, or equivalent bodies strengthen your application.
Step 5: Establish Physical Premises
A testing laboratory requires a physical space. This is non-negotiable — you cannot operate this activity from a flexi-desk or virtual office arrangement. Your premises must be suitable for laboratory equipment: adequate power supply, secure storage for client stones, and controlled access. Sign a tenancy contract (Ejari-registered for mainland) before proceeding.
Step 6: Equipment and Technical Setup
Core equipment includes spectrometers, refractometers, polariscopes, UV lamps, and potentially FTIR or Raman spectroscopy instruments for advanced treatment detection. Budget for calibration and maintenance as recurring costs.
Step 7: Obtain Sector-Specific Approvals
Depending on your scope, you may need approval from the UAE's accreditation body (ESMA — Emirates Authority for Standardisation and Metrology) if you intend to issue certificates with formal accreditation status. Laboratories issuing commercially relied-upon reports are expected to operate under ISO/IEC 17025 standards. Check current requirements through the Official UAE Government Portal.
Step 8: Register for VAT
If your anticipated annual turnover exceeds AED 375,000, VAT registration with the Federal Tax Authority is mandatory. Testing and certification services are generally standard-rated at 5%.
Step 9: Hire and Comply with Labour Law
All employment contracts must be registered through the Ministry of Human Resources and Emiratisation (MOHRE). Emiratisation quotas apply to mainland businesses above certain headcount thresholds — factor this into your hiring plan from day one.
Step 10: Collect Your Licence and Commence Operations
Once all approvals are in place and fees settled, your trade licence is issued. Renew annually. Keep your premises contract, insurance, and professional certifications current — lapses affect renewal eligibility.
Regulatory and Compliance Considerations
Diamonds in the UAE are subject to the Kimberley Process Certification Scheme (KPCS), which governs the trade of rough diamonds to prevent conflict financing. Your laboratory may be called upon to support KPCS compliance documentation for trading clients. The Ports, Customs and Free Zone Corporation (PCFC) oversees customs and trade compliance at Dubai's ports — understanding their procedures is relevant if your clients import or export stones through Dubai.
Anti-money laundering (AML) obligations are also relevant. Dealers in precious stones above certain transaction thresholds are designated non-financial businesses under UAE AML law. As a laboratory servicing these traders, understand where your own obligations begin and end.
Conclusion
A Diamond & Precious Gemstones Testing Laboratory in Dubai is a technically demanding but commercially well-positioned business. The city's role as a global gem trading hub creates consistent, high-value demand for credible, independent testing. The regulatory path is clear if you approach it methodically — choose the right jurisdiction, secure proper premises, invest in qualified personnel and equipment, and maintain accreditation standards.
This is not a business you set up over a weekend, but it is one with durable demand and meaningful barriers to entry that protect established operators. If you have the technical credentials and the commercial intent, Dubai is the right address.
