Many thanks! Can I ask what would be the value of akoya baroque pearls - 72 inches with 14K gold clasp?
		
		
	 
Value. There is 
replacement value, for insurance purposes, and there is 
resale value. Replacement value is higher and is based on what similar new items are currently selling for.
I saw a very long rope (84" if I recall correctly) of baroque akoyas at Nordstrom around 4-5 years ago that was selling for several hundred dollars. They were smallish pearls, maybe 7-7.5mm. It was a nice rope and I was surprised at how affordable it was. (I didn't buy it.)
Larger akoyas or akoyas with exceptionally thick nacre that is unlikely to chip can go for more, but still less than round akoyas of good quality, just because the market prefers round pearls.
As to 
resale value, the fact is that pearls do not tend to hold their value, unless they are historic pearls, natural pearls or a famous brand like Mikimoto. Pearls tend to deteriorate over time thanks to wear and tear, body oils and sweat, contact with cosmetics, pollution, poor storage, etc, etc. All of this drives the resale price down. We generally recommend to people who wish to sell their pre-owned pearls that they look at auctions sites and see what similar items sold for recently.
