This is mainly because white gold prongs offer greater support to the center stone of a diamond white gold engagement ring. This will help buyers to ensure that the diamond in their ring will not fall off from the setting. Apart from white gold, a number of metals such as yellow gold, rose gold, platinum, and palladium are used to design diamond rings. However, white gold is usually the most common choice of jewellers for making prongs even when the remaining part of the ring is made of a different metal. Diamond ring manufacturers and jewellers prefer white gold prongs because they are highly durable, yet very much affordable. Diamond ring prongs that are made of silver and pure yellow gold break more easily because these metals are relatively soft. On the other hand, diamond rings with white gold prongs last for a very long time even with minimum care. However, if the white gold prongs in your diamond ring are exposed to chlorine or other chemicals found in detergents or tap water, then they will surely get damaged. So, it is best to remove your diamond ring while you are taking a shower or cleaning your house.
