About 18k Gold Vermeil

Vermeil(pronouncedver-may) is a premium fine-jewelry material — a base of solid 925 sterling silver bonded with a thick, durable layer of solid gold. Under the U.S. Federal Trade Commission standard, a piece must carry at least2.5 micronsof 10k gold or higher to be sold as vermeil.

This piece is plated with5 microns of solid 18k gold— twice the FTC minimum — over a 925 sterling silver core. You get the warmth, lustre, and richness of solid 18k gold jewelry, the lightness and hypoallergenic comfort of sterling silver, and a finish engineered to last for years of regular wear.

Independently Certified

Every diamond we sell is independently graded and certified by one of three internationally recognised gemmological laboratories — your guarantee of authenticity, accurate carat weight, and verified clarity and colour grade. The applicable certificate ships with your order.

Care & Maintenance

To keep your 18k Gold Vermeil piece looking its best for years:

• Store in a soft pouch or lined jewelry box when not worn — separate from other pieces to prevent scratching.
• Avoid contact with perfume, hair products, lotion, chlorine, and prolonged moisture.
• Remove before showering, swimming, exercising, or sleeping.
• Clean gently with a soft microfibre cloth — do not use harsh chemical jewelry cleaners on vermeil.
• With normal care, the 5-micron 18k gold layer retains its lustre for years of regular wear.

Return & Exchange Policy

Returns & Exchanges — Summary

A quick summary of how returns work at GemHub & Co. Most pieces are made to order; ready-stock items come with a 30-day return guarantee and a free first return.

Two Return Paths

Almost every order falls into one of two categories — we tell you which on each product page.

Made-to-Order & Engraved Items

Most GemHub & Co. pieces are crafted specifically for you. These, along with customised and engraved items, are final sale and not eligible for return or exchange — except where the item arrives defective or we have made an error, in which case we replace or fully refund it at no cost to you, including return shipping.

Cancellations are accepted within 24 hours of ordering only; production begins within 5 hours of payment.

Stock Items — 30-Day Returns

Ready-stock (non-custom) items may be returned within 30 days of shipment, or exchanged within 45 days.

  • Free First Return (Stock Items): Your first return on an eligible stock order ships free with a prepaid, insured label. No restocking fees — you receive a full refund of the item price.
  • Refunds are issued via your original payment method.

The Essentials

  • Condition: Returned items must be unworn, in original packaging, with all certificates. A missing certificate incurs a 30% replacement fee per certificate.
  • How to Start: Email support@gemhubco.com for a Return Authorisation (RA) number before shipping. We’ll confirm the correct return address for your region in writing — customers in the US, UK, and UAE can usually return to a regional location without international shipping.
  • Refunds: Processed within 3 business days of inspection, via the original payment method. International refunds may take 5–10 additional business days.

Not sure whether your piece is made to order or ready stock? Email support@gemhubco.com before you place the order and we’ll confirm.
