This preview shows page 1. to view the full 4 pages of the document.
1. '5th' C Country of Region
2. 'Cut' what gives a diamond fire and brilliance
3. "Brilliant Cut" Enhance the beauty, not power. Maximized
outward fire and brilliance of the diamond
4. (3) Elemental
constituents of
a mineral
Major, Minor, Trace
5. (3) Kinds of
Crystal Faces
(1) Prism (2) Pyramid (3) pinacoid
6. 2nd most
common
diamond
group?
Type IIa
whitest colour with little to no absorption of
light across the visible spectrum
7. 4 C's Cut, clarity, colour, carat
8. 4 primary
native metals
Gold, silver, copper, platinum (metallic
bonds)
9. 4-fold tetrahedral
10. 6-fold octrahedral, octahedron
11. 8-fold cubic, hexahedron
12. 12-fold icosahedral
13. 18K 75% pure
14. 22K 92% pure
15. 24K = pure gold
16. Asthenosphere The upper mantle material acts as a
relatively soft, lubricating layer over which
the crustal lithospheric plates move.
17. Best color for
Diamond?
"D"
18. Blue Nile Honest and secure company, users can
compare diamonds of diff. sizes, shapes,
quality
19. Bonding:
Colvalent
(1)Common in organic compounds
(2) Ex Diamond: Carbon atoms share
electrons b/w them in tight 3D network
forming molecules of interconnected C
atoms
(3) Bonds are very strong
20. Canada's 3rd
diamond mine
Jericho Project
21. Canada's
production of
PGMs come
from?
the Lac des Iles operation near Thunder Bay
and as a secondary product from the
Sudbury Complex's nickel deposit in
Sudbury, Ontario.
22. Canada's
second
diamond mine
Diavik
23. Characteristics
of 4 primary
native metals
Conductive, dense, malleable, ductile,
metallic lust
24. Chromophores elements that cause color in minerals.
Usually trace
25. Color in
minerals is
caused by (2)?
Absorption or refraction of light of
particular wavelengths
26. Continental
crust
much richer in mineral containing silicon
(Si) and much thicker
27. Convergent (same direction): Destructive. Move toward
each other and collide. Ex, Himalaya
mountains (continental-continental). One
plate is pushed under or subducted below
the other. When two oceanic plates collide,
volcanic island develop above zone of
subduction. Oceanic-Continental: oceanic
plate is always subducted below continental
plate because oceanic crust is denser than
continental material. Ex. Mountains like
the Cascades.
28. Crown Top half
29. Crystalline
substances
Eg. Minerals
Have crystal lattice, symmetry,built up of
molecules called unit cells, unit cells are 3D
30. Culet Point at the bottom
31. Cullinan I AKA the great star of Africa. "potentially
flawless."
32. Cullinan II AKA the Lesser Star of Africa
33. D,E,F Colorless
34. DeBeers Control entire diamond market since 1888
35. Depth what you call the full length of diamond
36. Diamond
Laboratories
will?
Cut quality, color, clarity,carat weight,
origin, physical dimensions
37. Diamonds
occur in?
Primary and Secondary Deposits
38. Divergent (diff direction ←→ ): Constructive. Move
away from one another, and new crust is
produced. Can form within continental
plate to for new ocean basin. Ex. Mid-
atlantic ridge, widening atlantic ocean at
rate of 2.5 cm/yr.
39. Do
compounds,
including
minerals have
to be a charge
neutral?
Yes
