Description
Building on the knowledge learned in Talking Diamonds, this course will help the student to recognize the physical and optical properties of diamonds and diamond imitations. REQUIRED TOOLS: A 10x triplet jewellers loupe (single magnifying lenses, doublets or instruments with a focal length of more than a few inches are inadequate), jewellers tweezers (cosmetic tweezers and stiff utility tweezers may not be used), and gem cloth. Students may bring their own instruments or purchase from the CGA – add the items you want to purchase below.
If you not have already done so, make sure you complete and submit the ENROLMENT FORM.
About the Course:
This 10-hour (2 day)course will help the student to recognize the physical and optical properties of diamonds and diamond imitations. Gemmological instruments are used to distinguish between imitations of diamonds such as cubic zirconia, synthetic moissanite, Zircon and synthetic spinel. We will build on the knowledge learned in Talking Diamonds.
Syllabus:
- Use gemmological instruments to identify diamond and its imitations.
- Observing and recognizing levels of dispersion and brilliance with the naked eye.
- Use a loupe to observe hardness, double or single refraction, surface features, internal features, treatments and composite stones.
- Use of a thermal conductivity diamond tester.
- Use of a polariscope to help identify diamond simulants.
- Use of UV light to identify diamond simulants.
- Use of a gemmological microscope to identify hardness, double or single refraction, pavilion flash, surface features, internal features, treatments and composite stones.
Refund Policy:
Full refund: The Canadian Gemmological Association shall refund 100% of the fees paid by the person if the Canadian Gemmological Association cancels the program Partial refund: If a person has paid but withdraws with at least 10 (ten) days prior to the course; The Canadian Gemmological Association shall refund 80% (20% for administration fees) of the cost of the course. This request must be received in writing.
