Intro: Jewelers often ask whether micro-pavé tolerances in the EU are tighter than elsewhere. The short answer: there is no single EU legal tolerance for micro-pavé, but many European ateliers and suppliers work to tighter, documented shop tolerances. Those tighter targets come from design expectations, customer demands, and long-standing craft training — not from a […]

Introduction Matte and high polish finishes look different at first glance. One is flat and soft. The other is bright and reflective. In recent years, European-style matte and satin finishes have become more common in the U.S. jewelry market. Buyers want subtler surfaces, less maintenance, and looks that read as modern and handmade. This article

Intro: A diamond you wear in London on a cloudy day often looks notably whiter than the same diamond under bright San Diego sun. This isn’t magic. It’s optics, the sky’s color balance, the diamond’s cut, and how your eyes adapt. I’ll explain the physics and perception behind the difference and give practical tips so

Intro: Cold hands feel tight. Rings can slide off or feel loose. Does a London winter change fit more than California? Short answer: yes — but not for the reason most people assume. The body and the metal both react to temperature and moisture. The body’s response is far bigger. That means climate and daily

Intro: When families decide to sell an heirloom, the first practical choice is where to sell it. Auctions and consignment outlets are the two main routes. Which one people use differs between Europe and the United States. That difference comes from law, market structure, tradition, and simple economics. This article explains those differences and gives

Intro: People mix up “antique” and “vintage” because both words describe age, and sellers often use them loosely. The simplest practical rule used by museums, many dealers, and collectors is the 100-year rule: if a piece is more than 100 years old, it’s an antique. If it’s younger but clearly from an earlier era, it’s

Distance-Selling Gotchas: Can You Return Earrings? The Hygiene Exception Explained Buying earrings online is convenient. But returns can be tricky. Many countries give you a cooling-off right for distance sales, yet earrings often fall into a narrow hygiene exception.

Intro If you want to lower a jewelry business’s climate impact, you’ll face a common choice: buy recycled gold or buy carbon credits to offset mined gold. Both strategies can help, but they work very differently. Recycled gold reduces direct supply-chain emissions. Carbon credits try to cancel emissions elsewhere. Which actually cuts your footprint depends

Piercing jewelry often brings together two hard realities: metal chemistry and skin biology. The European Union treats nickel in jewelry as a measurable risk and sets strict limits on how much nickel can leach from an item. The United States has no matching federal ban. That difference matters if you buy piercings across borders, or

European retailers and miners have recently pushed mobile apps that claim to trace a diamond from mine to retailer. These tools promise to show origin, grading data, and chain-of-custody records on your phone. The idea is simple: give the buyer verifiable information so they can make choices about ethics, authenticity, and value. But how meaningful
