The American Gem Society is the country’s preeminent jewelry trade organization dedicated to consumer protection. Founded by Robert M. Shipley and several other leading jewelers and gemologists in 1934, the American Gem Society is a not-for-profit trade association of over 3,500 jewelers, retailers, suppliers, individual titleholders and affiliates. These members have dedicated themselves to:
· Consumer protection
· Ethical business practices
· Development and maintenance of superior gemological skills and knowledge
To qualify for membership in the American Gem Society, a firm must meet the highest standards of business conduct. A member firm can, and will be, expelled for unethical or deceptive practices. To ensure excellence in our Society, individuals must pass examinations on diamonds and colored gemstones before advertising their AGS membership. Every member firm must have at least one Certified Gemologist on staff, the highest accreditation in the jewelry industry. This process ensures that every AGS-certified jeweler you meet is at the top of their game, and more importantly, each one has pledged to protect you, the consumer.
A TRADITION OF SCIENCE AND EDUCATION
Established in 1931, the Gemological Institute of America is the world’s foremost authority on diamonds, colored stones, and pearls. GIA exists to protect all purchasers of gemstones, by providing the education, laboratory services, research, and instruments needed to accurately and objectively determine gemstone quality.
Ensuring the Public Trust
A nonprofit institute, GIA’s mission is to ensure the public trust in gems and jewelry by upholding the highest standards of integrity, academics, science, and professionalism through education, research, laboratory services, and instrument development. GIA attained its leadership role through decades of integrity and ingenuity, and everything we do is still driven by this mission.
A Place of Learning
GIA is where students from all over the world build successful careers in the gem and jewelry field. The Graduate Gemologist (G.G.) diploma, which focuses on gem grading and identification, is the industry’s highest professional credential. And with its Graduate Jeweler, Applied Jewelry Arts, and Accredited Jewelry Professional programs, GIA offers training geared to every aspect of the industry.
A Place of Breakthrough Discoveries
GIA is the global leader in gemological research, and its findings serve to protect the consumer. Using sophisticated technology, Institute researchers analyze thousands of samples each year. When new synthetic gems and artificial enhancement processes enter the marketplace, GIA is there to detect them. GIA manufactures gemological instruments used by gem and jewelry professionals everywhere. GIA Instruments’ precision microscope and many other products help them buy, grade, and appraise with confidence.
A Place to Turn for Unbiased Analysis of Gemstone Quality
GIA is the world’s most respected gemological laboratory, entrusted with grading and identifying more gems than any other lab including the Hope, the Taylor-Burton, the De Beers Millennium Star, and the Incomparable. Located in major gem and jewelry centers around the world, GIA laboratories are staffed by expert diamond graders and gemologists, whose work sets the standard for grading practices worldwide.
A Tradition of Discovery and Innovation
Since the 1930s, GIA researchers have made numerous breakthrough contributions to our understanding of gems. These milestones include:
- Creating the D-to-Z color scale and Flawless-to-I3 clarity scale for diamonds (1953), internationally recognized standards for evaluating diamond quality
- The first study of a new gem, tanzanite (1968)
- Distinguishing natural from synthetic diamonds (1995)
