The hallmark "HB" cojoined typically refers to a specific maker's mark used on silver items, indicating that the piece was made by a particular silversmith or company. The "H" and "B" are often initials representing the name of the artisan or business, and their conjoined design signifies a unique identification for authenticity. This hallmark helps collectors and buyers verify the origin and quality of the silver item.
It's simply the manufacturer's name, short for "H and Company" - which would make it probably a UK rather than US firm.
A ring with the imprint H925 typically indicates that the ring is made of sterling silver, which is 92.5% pure silver. The "H" likely stands for "hallmark," indicating the authenticity and quality of the metal.
The 925 or .925 is the marking that indicates your jewelry is at least 92.5% sterling silver. If it were to say 10k or .925/18k it would indicate that the metal is either 10 karats gold, or sterling silver with 18 karats plated gold.. The H is the manufacturer's signature to ensure the customer can trust where the markings and jewelry has come from.
The nine to five states that the ring is at least 92 .5% sterling silver and the H is the Maker's Mark to ensure that the identity of the stamp is valid
