Hello Silver,
I wish your photos were somewhat larger, so details could be seen more clearly.
In recent years, a LOT of coral has been characterized as "angelskin," where I would disagree with that designation. Usually this is white coral with pink spots or streaks. Actual angelskin coral is pink—sometimes with darker pink spots or streaks. Another closely-related coral comes from around the Hawaiian Islands, that is usually a more-vibrant pink with considerable variegation. Whether this is "angelskin" is a matter of opinion, I guess.
Added to the above, there are imitations that are made to resemble coral—such as dyed bone and other materials. It may take a close detailed photo to differentiate.
Think of coral (essentially gem quality coral from the Mediterranean or South China Sea) as being the "skeleton" of a marine animal. Its composition is very close to mollusk shell—being calcium carbonate. So, although it is organic, it is also essentially an organically-formed mineral. Coral will resist many normal treatments that survive whatever is harmless to calcium carbonates. However, it is attacked by some acids, such as hydrochloric acid.
It is safe to get coral wet—since it is an ocean product. It is also safe to wash coral beads in warm soapy water, and use an old toothbrush to gently release old dirt.
Nevertheless, since you are dealing with an old intact necklace, be aware that it is possible the cords (that you say may be silk) may be compromised—and would possibly break during washing. Old necklaces, strung on silk or organic fibers, should be restrung every five to ten years, if they are worn often.
This is what keeps we bead-stringers in business (!).
Good luck. Jamey
I have these three examples of pink and pink & white coral. The coral beads on the left were purchased in Hawaii about 30 years ago, and I think it is the "more vibrant pink" coral that Jamey mentions. Very inexpensive at the time, maybe $9 for the necklace.
The small branch pieces in the center were sold to me very recently as angel skin coral. I'm not an expert so I don't know if this is accurate.
The cross is probably at least 50-60 years old and I purchased it about 5 years ago. It was sold to me as angel skin coral as well. It is a signed Native American piece. The pink color does not match the pink on the Hawaii necklace at all. The color rendition did not come out well - this coral is much more of a peach color than it shows (on my monitor at least).
As I said I'm not an expert, but recently I was looking high and low for some angel skin coral beads, and I did not find any of the size and shape of your graduated rounds necklace. I found only small beads & pieces and cabs. Note added: I was looking for inexpensive beads - there are a lot offered in the thousand-dollar range.
Hi Rosanna,
You are fortunate to have acquired Hawaiian pink coral at such a low price. In recent years it has become very pricy. Because the Pacific coral that is pink is a different animal than the Mediterranean coral that provides angelskin, it is difficult to compare one to the other—except to say both are pink. I will show my angelskin coral, that I bought in the 1970s when I can either find an image or shoot my necklace. (I'm reasonably sure I showed this in the Coral Lecture I presented some two years ago for YoneSF.)
Your central coral group appears to be the white-coral-with-pink-spots that is routinely passed-off as "angelskin" coral in recent years.
The cross (a very nice piece by the way), seems to have what I would call "salmon" coral. This has a flushed pink color, that is somewhat saturated, but not bright. You say it's peachy. OK, I know that color in corals too. But if the photo is not accurate for color, it's hard to identify specifically.

i found there is an image in my book on p. 53, but this one may be easier to see detail-
1 necklace and 2 bracelets, where the carved beads have small real red coral beads between as spacers-
The beads in the foreground are coral I believe. They are quite hard with pink spots and evidence of branching.
The beads in the background are carved from a very thick shell. They seem a bit softer, more matte with sweet pink and white layers.
Hope it all helps.
