Materials & Care
Precise terminology, plainly stated.
Metals: karat vs. carat, solid vs. plated, hallmarking. Gemstones: natural vs. lab-grown, the 4Cs.
What it's made of
Metals
Every piece is solid gold or solid platinum — never a base metal with a plated finish, which wears through over time. Gold is worked at 18kt (18 parts pure gold out of 24, roughly 75%), the standard we use across yellow, white, and rose gold.
Karat, the measure of gold purity, is easy to confuse with carat, the measure of a gemstone's weight — the two are unrelated, and we keep them separate in every listing and receipt. Where applicable, a piece's hallmark (the official stamp certifying metal purity) is noted on its product page.
What it's made of
Gemstones
Natural and lab-grown stones are chemically identical — the difference is origin and price, and we state which one is in front of you on every listing and certificate, never left to be assumed.
- Cut
- How precisely a stone is faceted — the single biggest factor in how it catches light.
- Color
- Graded on an industry scale from colorless to noticeably tinted, for white diamonds.
- Clarity
- How free the stone is of internal inclusions, graded from VVS (very, very slight) down through VS and SI.
- Carat
- The stone's weight — 1 carat equals 200mg — distinct from a metal's karat purity.
Keeping it
Care instructions
- 01
Everyday wear
Remove rings and bracelets before swimming, exercising, or cleaning with household chemicals — chlorine and solvents dull metal finishes, and a hard impact can chip a stone.
- 02
Cleaning
Warm water, a drop of mild soap, and a soft brush is enough for most pieces. Freshwater pearls should only be wiped with a damp cloth — never soaked or placed in an ultrasonic cleaner.
- 03
Storage
Store each piece separately, in a soft pouch or a lined compartment, away from direct sunlight and humidity — stones and settings can still scratch each other in a shared box.
- 04
Professional care
Have prong settings and clasps checked by a goldsmith once a year. A loose setting is the most common cause of a lost stone, and it is straightforward to catch early.
