The deeper story

Industry Insight

18kt white gold is hallmarked according to country of manufacture, with '18K,' '750,' and '18ct' all serving as recognized purity marks for the same alloy standard. The numeric mark '750' reflects the fine gold content directly: 750 parts per thousand.

A Storied Heritage

The Hope, Koh-i-Noor, Cullinan, and Regent are named diamonds that have accumulated history in ways that other objects don't, through royal collections, political consequences, and centuries of documented provenance. They started as geological specimens and became cultural artifacts through the hands they passed through.

Trust & Service

Buying jewelry online requires trust in a way that in-store shopping doesn't. Ross-Simons earns that trust specifically: transparent product information, honest descriptions, clear return policies, and a service reputation built across seventy years of actual transactions.
