STF DIAMONDS carries the legacy of Susan Tiffany Jewelry — a Slauson institution for over thirty years — now in the hands of Jaqueline Kim, who started on a jeweler's bench in South Central at seventeen. Crown Jewelry, a beloved cafe, hundreds of custom pieces a year: every chapter led here. Time is precious. Gold is precious. Sincerity outlasts them both.

Lengths are measured with the chain open, end to end. Where it sits varies slightly with build and link size.
| Length | Where It Sits |
|---|---|
| 16 in | Snug at the base of the neck — a collar fit, most common for chokers and shorter pendant chains. |
| 18 in | Rests at the collarbone — the classic pendant length for most women. |
| 20 in | Falls just below the collarbone — the most popular starting length for men's chains. |
| 22 in | Sits at the top of the chest — comfortable over a t-shirt or with a small pendant. |
| 24 in | Hits mid-chest — a relaxed drape that suits medium and heavier chains. |
| 26 in | Falls below mid-chest — a longer look, good for layering over another chain. |
| 28 in | Reaches the sternum — a statement length for bigger links and larger pendants. |
| 30 in | Drops toward the abdomen — the longest standard length, worn loose over clothing. |
