FAQ

Buying from FCS.

The questions wholesale buyers ask first — lab diamonds, IGI reports, MOQ, lead times and OEM.

What are lab grown diamonds?

Lab grown diamonds are real diamonds created in controlled laboratory environments. They have the same physical, chemical and optical properties as mined diamonds, typically at a more accessible price point.

Do you provide IGI certificates?

Yes. Our IGI Certified Diamonds come with independent IGI grading reports covering carat, color, clarity and cut where applicable.

What is your MOQ?

We support flexible, low MOQ for jewelry and diamonds. Many items can start from 1 piece — please request a quote for your assortment.

How long is the shipping / lead time?

Typical lead time for ready styles is about 3–7 days after order confirmation. Custom OEM/ODM timelines depend on design and materials.
