abalone pearl

[12wentworth]

Hi! Once again I took a chance on an abalone pearl. The two I have previously purchased have been very lovely but each broke apart after wearing a few times as they were thin and hollow. I spotted this one last night and bought it right away for $30, as it seems to be largely intact and weighs 7 grams. What do you think and how can I strengthen it? I would lie to wear it but if I can't I will hang it in a window of my fish room.

Since it's already been drilled, I don't know how you could strengthen it.
The price seems really low for an abalone pearl, but I'm not an expert.

Yes, the price was very low but I was thinking that maybe it's cracked or crumbling in places. I was hoping to buoy up those areas with a clear polyurethane or something. I don't know if this is a thing that can be done. It is drilled as a pendant and quite large at 38mx X 25mm.
