Gall Raiman

Owner & Master Gemologist

Gall Raiman’s passion for large diamonds began over three decades ago when he first earned his GIA and AGS certifications. Since that time, he has mastered the techniques and trends that are driving high-end jewelry design, and has established relationships with the finest diamond sources around the world.

His skills and expertise are the result of tireless study, hands-on experience in all aspects of the jewelry industry and above all, an insatiable appetite for what’s new in the gemological world which include the newest trends, designs, and a keen eye for rare treasures.

Raiman Rocks, located in Calabasas, CA, is a reflection of Gall’s core values, delivering flawless integrity, expert knowledge, uncompromised value, and exceptional service. Established in 2006, Raiman Rocks has become a wholesale leader in the Large and Natural Fancy Color Diamond industry, delivering exceptional diamonds at incomparable values.

Gall believes that when you act out of integrity and treat others as you would treat a friend or family member, a web of reciprocation is created that leads to mutual success. That is the spirit behind Raiman Rocks as it is our goal to see each and every one of our customers thrive and grow.


“Respect is earned. Honesty is appreciated. Trust is gained. Loyalty is returned”.
