"Having moved from Sydney, Australia to NYC as a jewellery designer,  the hardest transition was re-building my business associates. Meeting Ron, Heather and the team at A&C Gems was like a breath of fresh air."

Sumer Sayan

"Heather and Ron are our "go to" source for gemstones.  We are a custom jeweler in Kansas City, but the distance between us is never been a problem.  On important stones, they take pictures and we decide what to use for a specific project.  I recommend them."

Scott Krigel

"Excellent all around. Millie helped me pick out a blue zircon December gemstone to make into a necklace. First gem shop I stumbled upon and how lucky was I. Echo all the review below. No need for a high end, name brand jewelry store when you have A&C."

Cornelius Queen

"Amazing selection and dedicated customer service from a family-owned business in the heart of the Diamond District.
They are gems! :)"

Ron Sandor
Graduate Gemologist, GIA 1998

Ronnie grew up in the business and began working on the block selling crayon drawings as a toddler to his father's co-workers in the Diamond District. Eventually he worked after school and during school breaks as a runner, bench jeweler, and polisher for various manufacturers in the 1980's, and joined his mother, Agnes- the founder (and namesake) of A and C Gem, as a teenager, shortly after the death of his father, Joe (the first generation in the colored stone business!)

Heather Sandor
Chief Sparkle Maker

Heather originally started her career in Washington, DC as a sound man/junior producer with Canadian Television News network's Washington Bureau. She made the move to gems in the early 90's after marrying Ron, and joining him as a trusted partner who brings an entirely different background and mindset to A and C Gem Trading Corp.  Heather is a true color addict, with an eye for unusual color pairings, and a true desire to have a first class operation based on the best possible business practices for all involved- clients, employees, and suppliers!
