Peelerie works in solid gold alloys. 14K, which is 58.5% gold, is the balance most of our pieces are made in: rich in color and strong enough for daily wear. 10K (41.7% gold) is harder still; 18K (75% gold) carries a deeper color and is a little softer. Yellow, white and rose gold differ in the metals they are alloyed with, not in their gold content. Read more in Gold Integrity.

Sterling silver is 92.5% silver, marked .925. It is bright, workable and naturally darkens over time as it reacts with sulfur in the air, which a polishing cloth reverses. Some sterling silver pieces are plated in gold, and their product pages say so. Read more in Sterling Silver.

Every diamond Peelerie sells is lab-grown: pure carbon, crystallized in the same structure as a mined diamond, with the same chemical, physical and optical properties. A piece that includes an IGI grading report says so on its product page, along with its grade. Read more in the Lab-Grown Diamond Guide.

Where a piece is set with a colored gemstone, black onyx or a cultured pearl, its product page names the stone. Each behaves differently in wear; our Gemstone Guide and Black Onyx Guide explain how.
