Platinum is a natural partner of diamonds and has been favored by jewelers for thousands of years. Platinum is a precious metal with a purity of nearly 95%. Its sheer, rare and unique silver-white adds a unique sparkle to the diamonds and inlay base. Platinum is not affected by air and moisture, and once a platinum jewellery is built, its appearance will remain the same. This special metal plays a leading role in Van Cleef & Arpels' Snowflake collection. In order to ensure that customers purchase high-quality jewelry, VanCleef & Arpels jewelers have stamped all platinum jewels with a mark of purity. In France and other places, the quality mark of platinum is a dog head; But in the United Kingdom, the Netherlands and Switzerland, the logo is a portrait of a dog's head (Saint Bernard) and a scale of 950 per thousand.
