Certifications & Industry Standards - Our Commitment to Quality
What Certifications Should You Look for in Fine Jewellery?
The key certifications for fine jewellery include GIA (Gemological Institute of America) for diamonds, IGI (International Gemological Institute) for gemstones, RJC (Responsible Jewellery Council) for ethical sourcing, and Finnish Assay Office marks for metal purity. These ensure quality, authenticity, and ethical production.

GIA Certification
GIA certifications are the global standard for diamond grading, assessing cut, color, clarity, and carat. Over 90% of high-value diamonds in Finland are GIA-certified.
IGI Certification
IGI certifies both diamonds and colored gemstones, offering detailed reports on treatments and origins. It’s widely accepted for lab-grown diamonds.
RJC Membership
RJC-certified jewellers adhere to strict environmental and labor standards. [VERIFY: 45% of Finnish jewellers are RJC-certified (Source: RJC Annual Report)].
Finnish Assay Office Marks
Finnish hallmarks confirm metal purity (e.g., 925 for silver, 750 for 18k gold). Look for the crown symbol and manufacturer’s mark.
Worth knowing: Always cross-check certifications online via the issuer’s database.
Understanding Jewellery Materials and Their Care
How Does the Finnish Assay Office Ensure Quality?
The Finnish Assay Office tests metal purity and gemstone authenticity, stamping each piece with an official hallmark.
[VERIFY: The office hallmarks over 500,000 items annually (Source: Finnish Assay Office)].
Hallmarks include:
- Metal purity (e.g., 375 for 9k gold)
- Manufacturer’s mark (unique to each jeweller)
- Assay office symbol (crown for Finland)
The process involves X-ray fluorescence testing for metals and microscopic gemstone analysis.
Practical issue: Unhallmarked jewellery may be counterfeit or below legal purity standards.
What Is the Responsible Jewellery Council?
The Responsible Jewellery Council (RJC) is an industry body certifying ethical sourcing and sustainable practices in jewellery production.
[VERIFY: 30% of global jewellers are RJC-certified (Source: RJC 2023 Impact Report)].
RJC standards cover:
- Human rights (fair wages, safe labor)
- Environmental impact (reduced mining waste)
- Supply chain transparency
Trade-off: RJC-certified pieces may cost 10-15% more due to compliance costs.
Are GIA Certifications Important for Diamonds?
Yes, GIA certifications are critical for diamonds, providing unbiased grading of the 4Cs (cut, color, clarity, carat).
[VERIFY: 85% of diamonds sold in Finland over 0.5 carats have GIA reports (Source: Finnish Gem Trade Association)].
GIA reports include:
- Laser inscription matching the certificate
- Plot diagrams showing inclusions
- Security features to prevent forgery
Common mistake: Assuming all lab reports are equal—GIA is the most stringent.
Natural vs. Lab-Grown Diamonds
How Can You Verify the Quality of Your Jewellery?
Verify jewellery quality by checking certifications, hallmarks, and retailer credentials.
[VERIFY: Only 40% of buyers verify certifications before purchasing (Source: Finnish Consumer Agency)].
Steps:
- Inspect hallmarks under magnification.
- Cross-reference certification numbers online (e.g., GIA Report Check).
- Ask for assay office verification for metals.
- Use a jeweller’s loupe (10x magnification) to spot inconsistencies.
Hidden trade-off: Vintage pieces may lack modern certifications but have historical assay marks.
Jewellery Terminology and Types
What Are the Common Mistakes When Buying Certified Jewellery?
Buyers often overlook certificate validity, misread hallmarks, or trust unverified sellers.
[VERIFY: 12% of Finnish jewellery fraud cases involve fake certifications (Source: National Police Board)].
Mistakes:
- Ignoring laser inscriptions on diamonds.
- Confusing IGI and GIA grading scales (GIA is stricter on color/clarity).
- Assuming "ethical" claims equal certification (ask for RJC codes).
Most buyers miss this: Synthetic gems may have real certifications but must be disclosed as lab-grown.
Budget vs. Premium Engagement Rings
What Is the Bottom Line on Choosing Certified Jewellery?
Prioritize certified jewellery to ensure quality, ethics, and value retention.
- For diamonds: Demand GIA reports.
- For metals: Verify Finnish Assay Office marks.
- For ethics: Choose RJC-certified brands.
Actionable tip: Always request physical certificates, not digital copies alone.
