I'm Katie Silver, founder of Argent & Asher, and I've spent years sourcing coloured gemstones, diamonds, and precious metals for clients who want pieces that last for generations.
I've seen the best and worst of online shopping, from clients who secured modern heirlooms they adore, to others who nearly lost thousands to clever scams. This guide brings together everything you need to shop confidently, avoid mistakes, and own jewellery that truly tells your story.

- Fineness mark (e.g., 750 for 18k gold)
- Assay Office mark (London, Birmingham, Edinburgh, Sheffield)

Can You Trust Diamond Certificates Online?
A grading certificate describes a diamond’s cut, colour, clarity, and carat. Only some labs are reliable:
- GIA (global gold standard)
- IGI (widely accepted, especially for lab-grown)
- HRD (European, reputable)
Brand certificates (Cartier, Tiffany, etc.) provide authenticity, not grading. They complement, not replace, GIA-style reports.
How to verify a GIA report:
- Find the certificate number.
- Go to GIA Report Check
- Enter the number.
- Compare the details.
- Check the laser inscription on the stone.
Stat: Over 2.5 million GIA reports are verified online each year (GIA, 2024).
