Rio Grande app for iPhone and iPad

Rio Grande Jewelry Supplies Metal Markets App. Each business day, at noon Eastern Time, international metals dealer Handy & Harmon, Inc. sets its daily market price for the various precious metals. Their base price is derived from a variety of factors that affect the changing valuation of these metals. Rio Grande takes the base price as its daily metal market price and posts this daily price each business day by 12:30p.m. Eastern Time. Our prices for the next 24 hours (or until the next market price is published, when business days are interrupted by weekends or holidays) are then set using this metal market price.
