Jewelry should not be worn while participating in sporting activities or heavy labor. Diamonds may be chipped by a hard impact. Jewelry may be damaged or broken during strenuous activities. Do not allow your gold jewelry to come in contact with harsh chemicals such as chlorine and bleach. Remove your jewelry prior to entering a swimming pool or hot tub. Repeated exposure to even small amounts of these chemicals has a cumulative effect, causing gold to become brittle and susceptible to breaks and prong failure. Avoid self-repairing jewelry and it should never be forced, twisted, snapped, or tightened.
