How to read a diamond report? Questions to ask the seller
A laboratory report helps you understand the stone's characteristics; it does not make the decision on price, appearance, and personal preference on its own. The document must be read together with the product information.

Understand which stone the report belongs to
First, read the institution that issued the document, the type of report, and whether the stone is defined as natural or lab-grown. Do not confuse the report of the center stone with the total carat information of all small stones in the ring. Different stones in a product may be documented differently.
GIA reports include ratings such as carat, color, and clarity, as well as other features depending on the report type. The general cut grade given to standard round brilliant cut D–Z stones is not found in the same way for every shape. Do not assume a note that is not on the document from the product description.
Distinguish between carat and visible size
Carat is a unit of weight. Even if two stones have the same carat, their appearance from above may differ if their shapes and proportions vary. Examine the report's measurements, the product's actual photograph, and the setting's structure together. A list sorted solely by carat does not tell the whole story of a purchasing decision.
When comparing, place the same types of documents and similar product features side by side. Comparing a total stone weight to another product's single center stone weight is misleading. Ask the seller to clarify which numbers cover which stones.
The document does not replace the appearance and the price.
A grading report is a descriptive document; it does not guarantee the retail price or future resale value. When purchasing, evaluate the product's setting, craftsmanship, maintenance conditions, and return terms alongside the document.
Photographs and videos may have been taken under different lighting. If possible, request a comparison under similar lighting conditions. When you do not understand how the grades in the document appear, ask about the significance of the difference for your use instead of simply choosing the higher letter or number.
Five questions to ask before ordering
Clarify the origin of the stone, the distinction between center and total carat, the type of document to be sent, the metal fineness of the product, and after-sales services. Learn the seller's process regarding report numbers or document sharing in advance; do not act on assumptions later.
Check which document accompanies the product at Arte on the relevant product and FAQ pages. This guide does not promise a specific laboratory document for any product. The information provided for the piece you choose must be consistent with the order summary.
Frequently Asked Questions
- Does the report guarantee the diamond's price?
- No. It describes the stone's characteristics; it is not a guarantee of sale or resale price.
- Is the total carat the same as the center stone's carat?
- Not always. Total carat can cover more than one stone. Check the product description to see which stones are included in the total.
- Does every stone shape have the same cut grade?
- No. The type of report and the shape of the stone are important. Do not automatically apply the general cut grade GIA gives for standard round brilliant D–Z stones to other shapes.
