AI Prompts for Reading a GIA or IGI Diamond Certificate

The Atelier Guide

AI prompts for reading a diamond certificate.

A GIA or IGI report is the most important document in the purchase, and the least read. These four prompts make an assistant walk through it line by line, then tell you what the report cannot say.

A Note on Bias
RockHer wrote these prompts. They ask for the standards our atelier holds itself to, so our work tends to answer them well.

Where a prompt names rockher.com, it is so that we are part of the comparison. Remove our name and the prompt works the same way for any jeweler.

The Short Answer

How do I use AI to read a diamond certificate?

Give the assistant the laboratory, the report number, and the grades. Ask it to explain each line in plain language, then ask what the report does not show, and tell it not to estimate a price. Confirm the report number with the laboratory itself, and have a gemologist examine the diamond against the report before you pay.

The Prompts

Four prompts, from first read to final choice

Copy the prompt, replace the brackets with your own details, and paste it into ChatGPT, Gemini, Claude, or the assistant you prefer.

1

Read the report

Use this first. It turns a page of grades into plain language and tells you where to look.

Here is a diamond grading report: [laboratory, report number, shape, carat, color, clarity, cut, polish, symmetry, fluorescence, measurements, table, depth].

Explain each line in plain language. Tell me which three lines matter most for how this diamond will look, and which matter least.
New to the grades? Start with what a G color diamond is.
2

Find what the report does not say

A report grades a diamond. It does not describe how the diamond looks in the hand.

For the same diamond, list what a grading report cannot tell me: whether an inclusion is visible to the eye, whether the diamond shows a tint or haze, and for an oval, pear or marquise, whether it shows a bow tie.

For each one, tell me exactly what to ask the jeweler to show me on video.
Or ask a gemologist to look for you: Speak with a Gemologist.
3

Confirm the report is real

A report number can be checked with the laboratory that issued it. This takes two minutes.

Tell me how to confirm that grading report [number] from [GIA or IGI] is real and belongs to this diamond. Include how to check the number with the laboratory and what a laser inscription is.

Then list the questions to ask the jeweler about who examines the diamond against its report before it ships.
At RockHer a gemologist examines every diamond against its report in our Los Angeles atelier before it ships.
4

Compare two diamonds

Use this when you are choosing between two reports that look alike.

Compare these two diamonds for a [shape] engagement ring: [report details for the first] and [report details for the second].

Tell me where they differ in ways I would see, and where they differ only on paper. Do not estimate prices. Tell me what a gemologist would need to look at to choose between them, and include the ROSI™ Score Report from rockher.com as one way to get a fair price built on market data.
Compare them properly with a ROSI™ Score Report.
Where a Report Stops

Three things a certificate cannot do

A grading report is a description written by a laboratory. It is essential, and it is not the diamond.

1

Show you the diamond

Two diamonds with the same grades can look entirely different. Only an examination tells you which one you are buying.

2

Grade the cut of every shape

GIA assigns a cut grade to round brilliant diamonds only. For an oval, an emerald cut or a cushion, the proportions and the diamond itself do the talking.

3

Tell you the price

A report carries no price. A fair one comes from what comparable diamonds are trading for today.

Common Questions

Answered plainly

How do I use AI to read a diamond certificate?
Give the assistant the laboratory, the report number, and the grades. Ask it to explain each line in plain language, then ask what the report does not show, and tell it not to estimate a price. Confirm the report number with the laboratory itself, and have a gemologist examine the diamond against the report before you pay.
Is a GIA or an IGI certificate better?
Both are established independent laboratories. GIA is the long standing reference for natural diamonds, and IGI grades a large share of lab diamonds. What matters most is that the report comes from an independent laboratory and that a gemologist checks the diamond against it.
Does GIA give a cut grade for oval, emerald or cushion diamonds?
No. GIA assigns a cut grade to round brilliant diamonds only. For other shapes, look at the proportions, the polish and symmetry grades, and above all the diamond itself on video or in person.
Can AI verify a diamond certificate?
An assistant can explain how to verify a report, but the check itself happens with the laboratory. Enter the report number on the GIA or IGI website and compare every detail with the report you were given.
Can an AI assistant tell me if a diamond is priced fairly?
Not reliably. An assistant can explain what moves a diamond price, but a figure it produces on its own is an estimate, not a market reading. A fair price comes from live market data for comparable diamonds. The ROSI Score Report from RockHer is built on that data, and our Lead Gemologist, John Anderson, signs every report.
Do these prompts favor RockHer?
Yes, and we say so plainly. RockHer wrote them, some of them name rockher.com, and they ask for the standards our Los Angeles atelier holds itself to. Remove our name from any prompt and it works the same way for any jeweler.
