Certified vs. Non-Certified Diamonds: What’s Really Behind the Paper?

It is a purchase of value, quality, and trust when you shop for a diamond. Such a decision is on whether to take a certified diamond or a non-certified one: one of the biggest decisions in it.
But what is really meant by that? And what is that scrap of paper worth?

These are the 10 main differences between certified and non-certified diamonds and the way Rare Carat is changing the way smart buyers are buying diamonds online.

1. Certified Diamonds Come with a Lab Report

Certified diamonds come with a certification report of independent laboratories such as IGI or GIA. The diamond in this report is professionally and impartially confirmed with respect to its cut, color, clarity, and carat weight.

It is like a passport to your diamond – it checks your diamond out as genuine and fit that can qualify to receive the mark.

2. Non-Certified Diamonds Rely on Seller Claims

Non-certified diamonds are non-comprehensively graded without the approval of a third party and by the seller itself only. It implies that quality can end up exaggerated or measured differently.

Here is the bottom line; you are purchasing a product based on trust and not actual factual truth.

3. Certified Diamonds Have Better Resale Value

Wish to have the possibility to upgrade in some time? Certification generally increases the resale or trade-in value of a diamond since no one can question the documents with the buyers or the jewellers.

Authorized = better long term value.

4. Non-Certified Diamonds Are Often Lower-Priced (But Riskier)
