Long’s is proud member of the coveted American Gem Society. The American Gem Society is an association dedicated to setting and maintaining the highest possible standards of business ethics and professionalism in the jewelry industry. Only a small percentage of retailers that apply for membership in the American Gem Society are awarded membership. To earn membership a retailer must demonstrate exceptional diamond knowledge and strict business ethics year after year. So you can be assured that Long’s quality and service are unsurpassed both today and tomorrow.

Long’s is a proud supporter of the Platinum Guild International. Because platinum is the most durable metal, we recommend a platinum ring or a platinum head for your diamond. Due to its strength and resilience, platinum is the choice that best protects your diamond. Mountings are available in platinum, 14K and 18K white and yellow gold.
