Question 1: Which setting type surrounds the entire girdle of a gemstone with a metal collar?
- Prong setting
- Bezel setting (Correct answer)
- Channel setting
- Pavé setting
Correct answer: Bezel setting
A bezel setting features a metal wall or collar that encircles and secures the entire girdle of the gemstone.
Question 2: Which setting uses tiny raised metal beads to hold small stones across a surface?
- Bezel
- Channel
- Pavé (Correct answer)
- Tension
Correct answer: Pavé
Pavé setting uses small beads of metal raised from the surface to hold stones tightly in place, creating a jewel-paved appearance.
Question 3: What is the minimum recommended number of prongs for securely setting a round brilliant diamond?
- 2
- 3
- 4 (Correct answer)
- 8
Correct answer: 4
A minimum of four prongs is recommended to adequately secure a round brilliant diamond while allowing good light entry.
Question 4: How are stones held in a channel setting?
- By metal beads raised from the surface
- Between two parallel metal walls forming a groove (Correct answer)
- By a full metal collar around the girdle
- By the spring tension of the shank
Correct answer: Between two parallel metal walls forming a groove
In a channel setting, stones sit side-by-side in a groove cut between two parallel metal walls that grip their girdles.
Question 5: Which setting type uses the spring tension of the metal itself to grip the stone at two points?
- Flush setting
- Tension setting (Correct answer)
- Gypsy setting
- Burnish setting
Correct answer: Tension setting
A tension setting uses the inherent spring force of the metal shank to compress and hold the stone between two contact points.
Question 6: In a flush (gypsy) setting, where does the stone sit relative to the metal surface?
- Raised above the metal on prongs
- Level with or slightly below the metal surface (Correct answer)
- Suspended by beads above the metal
- Held by a full bezel above the shank
Correct answer: Level with or slightly below the metal surface
In a flush or gypsy setting, the stone is inset so its table sits level with or just below the surrounding metal, fully protecting the girdle.
