What We Do :
Prima Gems works across every stage of the gemstone pipeline, from sourcing, cutting, logistics, and client services.
Why B2B Only?
We work exclusively with designers, jewelers, and manufacturers to protect you and respect the supply chain. By staying within the trade, we ensure you fully benefit from the value we create from sourcing to cutting. Your success is our success.
How We Collaborate
DESIGNERS
If color stones are part of your design, we can help you in whatever you need. If you have an existing mounting and love one of our stones, we can even have it re-cut or customized to your mounting.
If not, we can start from scratch and make you a center piece right from the rough, based on your requirements.
We are also able to source single stones that are not in inventory through our diverse supply chain.
If you need side stones or calibration stones for accents – we stock these as well.

MANUFACTURERS
We specialize in bulk production of gemstones on a small and large scale.
We have a diverse, extensive and quality-consistent network of select rough suppliers and miners that give us access to our products right from the source. Our In-house Cutters and our dedicated Quality Control Team have complete control over the product being delivered to clients. We can take care of the smallest details needed for bulk manufacturing, so that your final products can always look and feel the same. We ship worldwide and can deliver directly to your jewelry factory as well. What are you waiting for to get in touch?

JEWELER OR A WHOLESALER
We have an extensive selection of single and calibrated gemstones stocked and ready to ship from our New York office. Our Sales Associates and Account Managers are happy to work with you on what you need in an expedited manner. If one of our gemstones is not in stock, we can still order and provide a delivery estimation through our extensive supply chain both in the United States and abroad.

Tanzanite
A rare gemstone with a signature play between deep blue and violet tones

May and Emerald
jocelyn rodriguezEmerald is May’s birthstone, and it’s not trying to be perfect. The color, the inclusions, the character — it all comes with the stone. Here’s why that’s exactly the point.
