The settings, posts, and backings are all made from polished 950 platinum. Platinum is the most rare of all precious metals, and the ideal choice for showcasing diamonds because of its superior strength and durability. Unlike other jewelry metals, platinum will not chip easily or wear down over time, and it never needs replating. Its gorgeous white sheen is rich and luxurious and can be easily maintained with just an occasional cleaning and polish. Platinum has a substantial feel and is slightly heavier than gold. It's also hypoallergenic, and therefore perfectly suited to those with metal sensitivities.
