Gregg

Gregg offers a diverse range of gemstones including loose diamonds, emeralds, garnets, and diamond rings — a mix that appeals to both jewelry retailers and high-end buyers. Being founded in 2000 shows the company has over two decades of experience in the gemstone trade, which can be a strong signal of reliability and market knowledge. However, the lack of verification on work email, phone number, and business documents raises concerns about identity and legitimacy. Buyers should request additional proof before placing large orders or sharing sensitive requirements. Without verified contact details, it's harder to confirm the company's real operations or respond to urgent inquiries. This makes due diligence essential when engaging with Gregg, especially for high-value gemstone transactions.
