ROSY Product Certificate & Quality Documentation
ROSY Product Certificate & Quality Documentation
A Product Certificate and an independent gemological Grading Report serve different purposes.
At ROSY Lab Diamonds, we deliberately distinguish between the documentation of your piece of jewelry and the independent examination of an individual diamond.
What is the ROSY Product Certificate?
The ROSY Product Certificate is part of the documentation for the purchased piece of jewelry.
It serves to record relevant product information in a traceable manner and to establish the connection between the piece of jewelry and its ROSY documentation.
What purpose does the ROSY Product Certificate serve?
Piece of jewelry
It documents the piece of jewelry purchased from ROSY and its product assignment.
Product information
Relevant information about the piece of jewelry can be clearly recorded.
Traceability
The documentation makes it easier to subsequently match the piece of jewelry with the available records.
Grading Report or Product Certificate?
Independent IGI Grading Report
Documents the gemological examination of a specific individual diamond by an independent specialist laboratory.
ROSY Product Certificate
Documents the piece of jewelry and its associated product information from ROSY Lab Diamonds.
What does the IGI Grading Report document?
An independent IGI Grading Report refers to the individual diamond examined.
Depending on the report, the following information, among other details, may be documented:
- Laboratory origin
- Carat weight
- Measurements
- Color
- Clarity
- Cut, where applicable
- Polish
- Symmetry
- Growth information
- Additional gemological information
When Do You Also Receive an IGI Grading Report?
For a single Lab Grown Diamond weighing 0.50 ct or more, you receive an independent IGI Grading Report from ROSY Lab Diamonds, as well as the ROSY Product Certificate.
Why Total Carat Weight Is Not the Same
For jewelry with multiple diamonds, the total weight of all stones used is often added together.
For the ROSY Standard, however, what matters is whether a single Lab Grown Diamond weighs at least 0.50 ct.
Individual Stone
A solitaire with a single lab grown diamond weighing, for example, 0.70 ct meets the 0.50 ct requirement.
Total Carat Weight
Many smaller diamonds can weigh a combined 0.70 ct without any individual stone weighing at least 0.50 ct.
How the 0.50 ct Rule Works in Practice
0.50 ct Solitaire
A single lab grown diamond weighing 0.50 ct meets the threshold.
0.80 ct Center Stone
A single lab grown diamond weighing 0.80 ct plus smaller side stones meets the threshold for the center stone.
Many Small Diamonds
A jewelry piece with, for example, a total weight of 1.00 ct does not automatically meet the threshold if each individual stone is under 0.50 ct.
Why Both Documents Can Be Useful
A larger individual lab grown diamond and the jewelry piece made from it have different levels of documentation.
The Diamond
The independent IGI Grading Report documents the gemological characteristics of the individual stone examined.
The Jewelry Piece
The ROSY Product Certificate documents the product and jewelry-piece level.
Together, these documents create a clear distinction between independent diamond grading and ROSY product documentation.
Transparency Instead of False Expectations
The ROSY Product Certificate should not be understood as an independent laboratory certificate, appraisal, or guarantee of future price development.
No Independent Laboratory Evaluation
This function is performed, where applicable, by the separate IGI Grading Report.
No value guarantee
The document does not guarantee any future resale or market value.
No price forecast
Market prices can change and are influenced by many factors.
Why should you keep your documents?
The product certificate and any available Grading Report are important documents for your jewelry piece.
- Keep the documents safely stored together with your purchase documents.
- Do not unnecessarily damage or label the originals.
- Document report numbers separately if needed.
- Digital copies can also be helpful.
- For an independent report, use the official online verification.
Which documents should I expect?
Jewelry piece without an individual stone of 0.50 ct or more
The ROSY product certificate documents the purchased jewelry piece in accordance with ROSY product documentation.
Individual Lab Grown Diamond from 0.50 ct
In addition to the ROSY product certificate, you will receive an independent IGI Grading Report for this individual diamond.
ROSY quality documentation at a glance
- The ROSY product certificate documents the jewelry piece.
- It is not an independent gemological laboratory report.
- An IGI Grading Report documents the examination of one specific individual diamond.
- Both documents serve different purposes.
- At ROSY, the IGI threshold applies from 0.50 ct per individual Lab Grown Diamond.
- The total carat weight of several small diamonds is not decisive for this.
- A product certificate is not a guarantee of future market value.
- Transparent documentation helps clearly distinguish the jewelry piece from the diamond information.
Understanding documentation. Trust through clarity.
Anyone who knows which document serves which purpose can clearly distinguish product information from independent diamond grading.
