GIA GIA Diamond Care, Maintenance & Consumer Education

Question 1

Which household substance can damage a diamond ring over time by slowly eroding the metal setting and prongs?

Accepted Answer

Chlorine bleach and chlorinated pool water

Answer

Chlorine can weaken and corrode gold alloys and platinum over time, increasing the risk of prong failure and stone loss.

Question 2

A GIA-educated consumer should be advised to have their diamond ring professionally inspected and cleaned approximately how often?

Accepted Answer

Once every 6–12 months

Answer

GIA recommends annual or semi-annual professional inspections to check prong integrity and clean hard-to-reach areas of the setting.

Question 3

What is the safest home cleaning method for a diamond ring recommended by GIA-trained jewelers?

Accepted Answer

Gently scrubbing with a soft toothbrush in warm water with a small amount of mild dish soap

Answer

Warm soapy water with a soft brush effectively removes oils and dirt without risking damage to the metal or stone.

Question 4

Why should diamond jewelry be removed before engaging in activities such as gardening, weight lifting, or rock climbing?

Accepted Answer

Impact and abrasion can chip the diamond and physical force can bend prongs, loosening the stone

Answer

Though diamonds are extremely hard, they can chip along cleavage planes upon sharp impact, and physical stress can deform prongs.

Question 5

What does a GIA-trained professional check for when inspecting prongs on a customer's ring?

Accepted Answer

Whether prongs are worn thin, bent, chipped, or have slipped below the girdle of the stone

Answer

Worn, bent, or displaced prongs are the leading cause of diamond loss in rings and must be identified and repaired promptly.
