Salmon Pink Coral. These gem-quality Coral beads are old, hand-cut, dating back to the early 1900s or before; when sourced recently (2024) in England they were simply strung on twine, no clasp, no Gold beads. Though gemstone Coral was a very great favourite in England, especially in the mid-1800s to early 1900s, this bead strand was probably not fashioned for the English market of the period, for the hand-cut beads, though reasonably matched in size and graduation, are not perfectly matched, and simply would not have met the market requirements of the England of that period.
The source of these gemstone beads, with their Salmon Pink Coral colour, would definitely have been the Mediterranean, but the cut of the beads is the so-called “native cut”, a sort of barrel-shaped, squat cut, commonly used in South India; however, this type of graduated gemstone Coral bead necklace is not, and was not, at all favoured in South India.
Best bet is that the above graduated Coral bead strand was cut in Sth India a hundred years ago from imported Mediterranean branch Coral for an English client and that it found its way eventually to England.
Here in Sydney it is professionally strung on red silk, knotted each bead, with a Sydney-handmade 18ct Gold “S” clasp and two 20ct Gold beads from Jaipur, North India  (a nice twist given that the “best bet” is almost certainly correct, that the beads were cut in India originally, a hundred years ago or more).
