GIA GIA Diamond Setting Styles & Jewelry Design

Question 1

Which setting style holds a diamond using small metal claws or prongs that grip the girdle of the stone?

Accepted Answer

Prong setting

Answer

A prong setting uses metal claws (typically 4 or 6) to grip the diamond's girdle, maximizing light exposure.

Question 2

A bezel setting encircles the diamond with a rim of metal primarily to achieve what benefit?

Accepted Answer

Protect the diamond's girdle and reduce the risk of chipping

Answer

The bezel setting's full metal rim protects the girdle and edges, making it ideal for active wearers.

Question 3

In a channel setting, stones are secured by placing them in a groove between two parallel metal walls without any prongs between gems. What is a key advantage of this style?

Accepted Answer

The smooth surface protects stones from snagging on fabrics

Answer

Channel settings create a smooth, snag-free surface because there are no prongs or metal between the stones.

Question 4

Which ring style features a wide metal band with the diamond set so its table is flush or nearly flush with the band surface?

Accepted Answer

Flush (burnish) setting

Answer

A flush or burnish setting recesses the diamond into the metal so it sits level with or just below the surface of the band.

Question 5

A tension setting holds a diamond in place using the compressive force of the metal band itself. What is the primary concern a GIA-trained sales professional should communicate to customers?

Accepted Answer

Resizing is difficult and may require professional reassembly of the setting

Answer

Because tension settings rely on precise metal compression, resizing must be done by a specialist and can be complex.
