I purchased my wife's engagement ring at a Helzberg store in Houston, TX. The service was excellent, and the ring comes with a lifetime warranty, including routine cleaning at the store. Helzberg is owned by Berkshire Hathaway, which I consider a reliable and reputable company. Berkshire Hathaway is led by Warren Buffett, who focuses on investing and holding well-established companies with honest and competent management teams capable of operating the business dependably. I chose Helzberg.com because I want to evaluate whether purchasing a ring or other jewelry online from Helzberg offers a similarly enjoyable and easy experience as buying in-store.
