• Does white gold require much maintenance?
• Can I buy mixed sets of say yellow and white gold rings?
• Types of gold available and their carats
• If I order a solid gold ring with a script inside then will it still have the metal quality carat stamp and other jewelers hallmarks inside?
• Do any of your rings contain nickel?
• Can I get a 22ct white gold ring made?
• I've heard that 14-carat gold is harder, but not as rich in color as 18 carats. What are the differences between the various gold types?
