Metals.
Three pages on the metals demi-fine houses use. Written plainly, ranked by longevity on skin, priced to the current spot rate.
Which metal, actually.
Vermeil, gold-filled, plated, solid. The differences show up at the 12-month mark, not on day one. Three pages, no jargon.
Vermeil vs plated
2.5 microns on sterling versus 0.5 microns on any base. The five-fold difference in wear.
Vermeil vs gold-filled
Vermeil layers gold; gold-filled bonds it under heat and pressure. Which one lasts longer, and why.
Every gold metal, ranked
Solid 10k / 14k / 18k, vermeil, gold-filled, gold-plated. What each one means on your skin.
