Sherman Diamonds

Sherman Diamonds is a jewelry and precious-metal buying business in Houston's Richmond Avenue corridor, near Greenway Plaza, that focuses on purchasing diamonds, fine jewelry, gold, and luxury watches for cash rather than offering general repair services. The business advertises appraisals from a certified gemologist, same-day payment, and a program that lets sellers buy an item back at full price within 21 days if they change their mind, positioning itself primarily as a place to sell or get cash for jewelry and watches rather than a repair or service counter. Rolex is the one watch brand directly confirmed in customer feedback, with a reviewer describing driving from San Antonio specifically to sell a Rolex there; other reviews describe selling fine jewelry and rings for a fair price, alongside some complaints about how items were evaluated. Given its focus on buying and appraisal rather than repair or servicing, Sherman Diamonds is best suited to Houston-area sellers looking to convert watches, diamonds, or gold into cash quickly, rather than shoppers seeking watch repair or maintenance.
