Diamond Certificate vs Insurance Valuation: What’s the Difference?

Diamond Certificate vs Insurance Valuation: What’s the Difference? 

When buying a diamond, you may come across both a diamond certificate and an insurance valuation — and it’s important to know they’re not the same thing. 

What is a Diamond Certificate? 

Also known as a diamond grading report, this certificate is issued by a gemological lab like GIA, IGI, or HRD. It provides a detailed assessment of a diamond’s characteristics, including: 

• Carat weight 
• Cut, colour, and clarity (the 4 Cs) 
• Measurements and proportions 
• Laser inscription (if applicable) 

This document confirms the authenticity and quality of the diamond. It’s not a financial valuation — rather, it’s an expert, objective analysis of the stone. 

What is an Insurance Valuation? 

An insurance valuation, sometimes called an appraisal, assigns a monetary value to your jewellery. It reflects how much it would cost to replace the item with something of equal quality. This document is typically required by insurers in the event of loss, theft, or damage. 

The valuation may consider: 

• The diamond’s quality and market conditions 
• The craftsmanship and brand value 
• Current retail prices 

In short: 

• Certificate = Quality grading 
• Valuation = Replacement cost for insurance 

Which should you have?

Ideally, you should have both — the certificate for transparency and the valuation for protection.

You should also consider taking out jewellery insurance on any piece you purchase, for that extra peace of mind. If you have any questions about which documents your The Diamond Store piece will come with, feel free to reach out to our team of experts, who will be happy to help answer them.
