Frequently Asked Questions
Are there any benefits I can access while studying with Gem-A?
As part of your student membership, you will have access to two online gemmology publications that are released quarterly: The Journal of Gemmology and Gems&Jewellery, as well as being eligible for a discount in the Gem-A Instruments shop. You will also have access to a special student ticket price for networking events such as the annual Gem-A conference. Students can also apply for a Totum Pro discount card (for UK discounts).
Can I re-do an assessment?
Unless there are proven mitigating circumstances, students will not be able to re-do any assessments. If you are in a situation that you believe would constitute mitigating circumstances, please contact your tutor as soon as you can. More information can be found in the Student Policies and Procedures.
Is there any help available for students with disabilities?
Gem-A can consider additional support for individuals who are disabled, have a learning difficulty or long-term medical condition. If this applies to you, please contact our Student Support Officer at studentservices@gem-a.com to find out more.
Do I need to take any precautions when using equipment?
Students will be using refractive index (RI) liquid in their practical gem testing sessions or lab classes when using a refractometer. RI liquid is commonly used in gemmology when using a refractometer. The Gem-A course extensively covers the appropriate use of refractometers, and therefore, to successfully complete the Gemmology Diploma, you will be required to use the RI fluid. In a classroom environment, the Gem-A tutors will provide you with appropriate information regarding the RI liquid, and you will be taught the recommended handling procedures. Only a tiny drop of RI liquid is used in testing, and the cap on the bottle is always replaced. It is your responsibility to ensure that you appropriately follow the instructions and information provided by your tutor on the use of the RI liquid. Gloves will be provided if you require them when using the RI liquid at the London teaching center.
RI liquid contains diiodomethane, and you may need to exercise precautions if you are pregnant, if you have certain medical conditions, and if you have sensitivity to, or are allergic to, this chemical. Again, your tutors will provide the required information on handling procedures. Please inform your tutors so that they are aware of your needs. If you are unsure, contact your doctor for advice. If you are pregnant, please consider that you may also be sensitive to the smell, which may make you nauseous.
If you are unsure about using RI liquid or if your doctor has advised against using it, please contact education@gem-a.com for further advice or for a copy of the Material Data Sheet.
