See What Our Clients are Saying
"When a bank sees a GIA report, they see a piece of paper. GemSource sees the real value."
I had a time-sensitive opportunity to acquire a valuable parcel of stones, but my capital was tied up in inventory out on memo. A traditional bank loan would’ve taken weeks and the deal would’ve been gone. GemSource understood the urgency. They offered a fair wholesale valuation on a 7-carat G VVS2 and delivered funds to my account in under 48 hours. Their speed and deep understanding make them a vital resource.

"The process was professional, discreet, and refreshingly straightforward."
As a multi-generational wholesaler, I was initially skeptical about collateral lending. But GemSource Capital changed my perspective. The process was discreet, professional, and straightforward. Their in-person verification was conducted by someone who truly understood the nuances of the stone not just the certificate. The valuation reflected real wholesale market conditions, not inflated retail estimates. For any dealer needing to bridge a cash flow gap without sacrificing prime inventory, GSC is the smartest solution I’ve found.
