A line of diamonds is only as secure as the point where it opens. The double latch clasp belongs on tennis bracelets, diamond line bracelets, and multi-strand necklaces because the closure has to match the value of the design.
Stone Story
Morganite's crystal structure produces material with relatively low inclusion density compared to other beryl varieties. Eye-clean specimens are commercially available at center stone sizes with clarity consistent across the color range. That availability distinguishes morganite from colored gemstones where inclusions become a significant constraint at larger sizes.
Visually Speaking
The box clasp doesn't project or rotate, which means the drape of a piece is uninterrupted at the closure point and the visual line reads continuously. It serves pearl necklaces and multi-strand bracelets particularly well.
