Eternally white, naturally enduring and 30 times rarer than gold, Platinum is ideal for anyone looking for a truly unique and timeless metal. Platinum engagement rings offer the durability and strength to protect your center diamond throughout the years. While Platinum is similar to white gold in appearance, it is naturally white so it rarely needs re-plating. Its non-reactive, hypoallergenic qualities make it an excellent choice of metal for those with skin sensitivity. Over time, Platinum develops a stunning finish, called the patina.
