At UPVIORA, every diamond we use is certified by the International Gemological Institute (IGI) — one of the world’s most trusted and respected diamond grading organisations.

This certification is your assurance that every piece of jewellery you receive meets the highest standards of quality, authenticity, and transparency.

What IGI Certification Means for You

When you choose IGI-certified diamonds, you’re choosing confidence.

Each diamond is independently assessed and graded by experts, ensuring that what you see is exactly what you get. The certification verifies the diamond’s key characteristics, including:

• 
  Cut – how beautifully the diamond reflects light
  
• 
  Clarity – the purity and presence of natural inclusions
  
• 
  Colour – the diamond’s colour grade on a precise scale
  
• 
  Carat Weight – the exact weight and size
  

This level of detail guarantees that your diamond is genuine, accurately graded, and fairly valued.

Why It Matters

In a world where trust is everything, IGI certification removes uncertainty.

It means:

• 
  No guesswork about quality
  
• 
  No hidden details
  
• 
  Complete transparency in your purchase
  

Whether you’re buying for a special occasion or investing in a timeless piece, you can do so with total peace of mind.

Luxury You Can Trust

Every UPVIORA creation combines the brilliance of lab-grown diamonds with the assurance of IGI certification — giving you jewellery that is as credible as it is captivating.

At UPVIORA, every piece of jewellery is officially hallmarked in the UK by the Birmingham Assay Office — one of the world’s most historic and respected authorities in precious metal testing.

This hallmark is your guarantee that the precious metals used in your jewellery meet strict UK legal standards for purity and authenticity.

What UK Hallmarking Means for You

A hallmark is more than just a stamp — it’s a mark of trust.

Each UPVIORA piece is independently tested and verified to confirm the purity of the metal, whether it’s gold, silver, or platinum. The hallmark typically includes:

• 
  Metal Purity Mark – confirms the fineness (e.g. 925 silver, 375/750 gold)
  
• 
  Assay Office Mark – shows it has been tested by a certified UK authority
  
• 
  Sponsor’s Mark – identifies UPVIORA as the registered maker
  

This ensures that what you’re purchasing is genuine, compliant, and exactly as described.

Why It Matters

In the UK, hallmarking is a legal requirement for precious metals — but it’s also a symbol of quality and integrity.

For you, it means:

• 
  Guaranteed metal authenticity
  
• 
  Protection against misleading claims
  
• 
  Confidence in long-term value and durability
