Frequently Asked Questions
Detailed standards regarding ring sizing, metallurgical alloy purity, routine studio maintenance, and secure armored logistics.
Ring & Chain Sizing Guide
Ring sizing is measured by the internal diameter in millimeters. Finger volume naturally fluctuates with temperature and time of day; we advise measuring at room temperature in the afternoon.
If between sizes, we recommend selecting the larger size for wide bands (over 3mm) and the standard size for fine wire bands like our Thread Band.
| US Size | Inner Diameter (mm) | Inner Circumference (mm) | UK / AU | EU |
|---|---|---|---|---|
| 4.0 | 14.9 mm | 46.8 mm | H | 47 |
| 5.0 | 15.7 mm | 49.3 mm | J ½ | 49 |
| 6.0 | 16.5 mm | 51.9 mm | L ½ | 52 |
| 7.0 | 17.3 mm | 54.4 mm | N ½ | 54 |
| 8.0 | 18.1 mm | 57.0 mm | P ½ | 57 |
| 9.0 | 19.0 mm | 59.5 mm | R ½ | 60 |
Materials & Hallmarking Standards
18k Recycled Solid Gold (AU 750)
Composed of 75.0% pure gold alloyed with silver and copper to optimize tensile rigidity and impart a warm, non-brassy champagne hue. 100% recycled from verified European industrial and jewelry refining loops.
14k Recycled Solid Gold (585)
Composed of 58.5% pure gold. Exceptionally scratch-resistant and suited for pieces subject to high impact, such as wire bangles and signets. Certified with national assay office marks.
18k Heavy Gold Vermeil
Unlike standard electroplating, our vermeil features an ultra-dense layer of 3.0 to 3.5 microns of 18k gold electro-bonded over a core of pure 925 sterling silver. Meets French and Swiss luxury vermeil standards.
925 Sterling Silver (AG 925)
92.5% pure silver with 7.5% copper. Finished with an anti-tarnish microscopic passivating seal. Stamped with our registered atelier hallmark and official silver purity assay mark.
Care & Cleaning Procedures
Daily Maintenance: Gently buff your piece with the unbleached cotton polishing cloth included with your dispatch box. This removes skin oils and dust without abrading satin texture or hallmark stamps.
Deep Cleaning: Soak solid gold or diamond pieces in a bowl of warm water with mild, pH-neutral dish soap for ten minutes. Clean behind bezels with an ultra-soft natural bristle toothbrush. Rinse under lukewarm water and pat dry with lint-free cloth.
Precaution with Organic Gems: Never submerge freshwater pearls or porous stones in chemical dips or ultrasonic machines. Put on pearls last after perfumes and cosmetics have evaporated.
