Diamond Vault topples perpetual winner Tapper's this year, earning accolades for its personalized, low-pressure service and superior diamonds at knockout prices. Established in 2003, the store's owners bring with them nearly 50 years of experience in the jewelry biz, which they use to educate customers in the intricacies of diamonds, custom designs and all aspects of jewelry purchasing. Personalized appointments are preferred, so staff can work closely with customers and involve them in every step of the design process. The individualized attention means you receive the glittery gem of your dreams — and most likely a yes if you're popping the question.
