Jewelry Buying Guides

Every guide below is written by the people who make the pieces: diamond grading, ring sizing, setting durability, metal care, and how a custom order actually moves through a manufacturing facility.

Written by Edwin Lin, founder of Redora Jewels, with the production team in Shenzhen. Redora manufactures custom fine jewelry, which is stated openly so each guide can be judged on whether the specifications hold up.
