Platinum is a precious metal that is very hard and heavy. We use an alloy that is 95% platinum. It is almost as white as silver,  hypoallergenic, very hard, will not tarnish and very expensive. Platinum is very dense and about 80% heavier than 14K gold. We do not cast our own platinum and have difficulty changing the size of a platinum ring so if you choose platinum please plan at least a month lead time. To estimate the cost of a platinum ring multiply the 14K cost by 3.5. 

 50% of the cost of the platinum ring is charged when the order is placed and the balance when the order is complete.
