real coral, or a fake? 🪸 ☀️

I've bought this from a relatively popular jeweler for just $150 (8mmx24ish/ 32inches). The item was originally sold out so they kindly reached out to their vendor and bought more coral; then made this strand for me.. I just committed to buying several more strands, and then I realized I've made a commitment of spending several hundreds of dollars without knowing if this coral is real or not. This is because they asked their vendor for more strands specifically for me, to for my second custom order. I am not sure if it's important to the jeweller to know whether or not these beads are real; but I am rather conflicted now. I'll be grateful for your advice.
I can say I have been wearing the necklace with glee, and an array of other strands - like pink conch, pink opal, rose quartz. I think it's just time that I stop wondering about the authenticity of this material and accept the truth whatever that may be.
Thank you all for your help.
