GIA GG exam-day guide
GIA GG · Prepare for the day ahead.
Your checklist
Bring government-issued photo ID
Use the exact name that appears on your GIA enrollment record. If the names differ, contact GIA before the test day to correct the record; a mismatch can bar entry. Confirm the accepted ID types with the provider, since rules vary by test center and by remote-proctoring vendor.
Bring your appointment confirmation and eligibility details
Have the confirmation number, your GIA student or client number, and the exam name and date available, either printed or on your phone. You may be asked for these at check-in or if a scheduling problem arises.
Confirm which exam section you are sitting and its format
The GG practical exam is a hands-on gemstone identification and grading assessment using stones and equipment supplied at the test site. Reconfirm the section, time allowance, and whether any portion is computer-delivered when you receive your appointment notice, and confirm with the provider if anything is unclear.
Bring your own loupe (10x) and tweezers
Personal loupes and tweezers are normally permitted and are what you have trained with. Label them. Confirm with the provider whether any other personal instruments are allowed, because rules on additional equipment vary by site.
Leave prohibited items behind or plan to store them
Phones, smart watches, notes, reference charts, and study materials are typically not allowed in the testing room. Most centers provide a locker; confirm storage arrangements with the provider in advance.
Plan your travel and arrive early
Aim to arrive well before your reporting time, typically 30 minutes, to allow for check-in, ID verification, and security procedures. Confirm the exact reporting time and location with the provider, and check local traffic and transit on the day.
Know how to get to the site and where to park
Do a route check the day before. Note the building entrance, floor, and suite number from your appointment notice, since large testing centers can be hard to navigate.
Prepare for a long, focused session
Practical grading requires sustained close observation. Get a full night's sleep, eat a proper meal beforehand, and confirm with the provider whether food, water, or breaks are permitted in or near the testing room.
Review your own method, not new material
In the final day, rehearse your systematic approach: observation with the loupe, refractive index and other instrument readings, and structured grading notes. Do not attempt to learn new species or treatments at the last minute.
Check any accessibility or special-accommodation arrangements
If you requested accommodations, confirm in writing that they are approved and will be in place. Raise any concern with the provider before the test day, not at check-in.
Dress in layers and comfortably
Testing rooms can be cool, and you will be seated and leaning over a microscope or stones for extended periods. Avoid loose sleeves that can catch on equipment.
Confirm the reschedule and cancellation policy
Know the deadline and any fee before the final 72 hours, in case of illness or emergency. Confirm the exact terms with the provider, as they are set by GIA and can change.
Plan the day
Stop broad review. Re-read your own summary sheets on identification criteria, treatments, and grading nomenclature, and rehearse your step-by-step procedure out loud. Confirm your appointment time, address, and ID requirements, and print or download your confirmation. Check the weather and transit plans. Protect your sleep schedule starting now.
If you have practice stones, run timed drills using the same sequence you will use on the day: unaided eye, loupe, then instrument checks, recording each observation as you go. Practicing the routine under time pressure matters more than covering new species.
Pack your bag: photo ID, confirmation, loupe, tweezers, and any permitted items. Lay out comfortable clothing. Confirm your alarm and transport. Do a light review only, then stop early. Eat a normal meal and go to bed at your usual time; cramming the night before tends to hurt close-observation performance.
Eat a real breakfast and hydrate, since breaks may be limited. Arrive at the site with buffer time. Leave your phone and watch in the locker or at home as instructed. At check-in, present your ID and confirmation, follow staff instructions, and use the restroom before you are seated.
Read the instructions and any scoring notes carefully. Note the total time and the number of stones or tasks, and budget your minutes per item. Set up your workstation so your loupe, tweezers, and any supplied instruments are within easy reach.
Apply the same systematic procedure to every stone: observe, test, record. Write down observations as you make them rather than relying on memory. If one item stalls you, mark your best answer, note the uncertainty, and move on so a single stone does not consume the time budget for the rest.
Reserve the last few minutes to check that every item has an answer and that your recorded observations match your conclusions. Do not make panicked last-second changes without a reason grounded in your notes.
Note which identification or grading calls felt uncertain while they are fresh, and record them for future study. Confirm with the provider how and when results are released and what the retake policy is, rather than assuming a timeline.
Rules to check
Bring the ID required by the provider and make sure the name matches your enrollment record exactly. If your ID name differs, resolve it with GIA before the test day; do not expect an exception at check-in.
Follow all instructions from test-center staff and proctors. Do not communicate with other candidates during the test, and do not attempt to view another candidate's work or answers.
Do not bring unauthorized materials into the testing room. Phones, smart watches, notes, reference charts, and study aids are generally prohibited; store them as directed and confirm permitted items with the provider beforehand.
Use only the equipment you are permitted to bring or that is supplied at the site. If you are unsure whether an instrument is allowed, ask the provider before the test day rather than at the workstation.
Ask the proctor before leaving your seat for any reason. Break and restroom policies vary by site and by whether the exam is proctored remotely, so confirm the specific rules with the provider.
Understand the scoring before you sit: results are reported by GIA according to its own grading and passing standards, and partial credit, section weighting, and retake limits are set by the provider. Confirm these details with GIA rather than relying on secondhand information.
Report any equipment malfunction, damaged stone, or unclear instruction to the proctor immediately. Do not attempt to fix equipment yourself or continue on a faulty setup without notifying staff.
Keep your conduct honest and your work your own. Attempting to copy answers, use hidden aids, or misrepresent your identity is grounds for invalidation of your results under the provider's rules.
