EnderX;
You asked for numbers...
What I gather in the first riddle leads me to believe it is amber. It comes in various colors, mainly represented as a golden substance, was known in ancient times, was believed through the ages to hold mysterious powers, was considered valuable, is a solidified form of a sap of a type of conifer, and has been discovered by many to have within its recovered pieces the remains of different bugs that became subsequently imprisoned--- extinct, ancient bugs.
The second riddle leads me to believe coral is involved. Not a plant, but an animal, each part is very small and beautiful; but, gathered together, coral can form some of the most treacherous and sharp reefs known.
The third riddle makes me think of ebony. This wood is prized for its color, its durability, its ability to take a lustre, and its incredible density. It is so dense that it will not float; and it, too, was known by the ancients--- who used it for fine cabinetry and ornamental pieces.
The fourth appears to be pearl. This, too, was highly prized through the ages; and, the East was where many pearls were harvested. Everyone has, of course, heard of "Mother of Pearl" also.
So it seems we have something involving treasure, ornamentals, trade, the East, and possibly a reef--- not to mention the sea. Now you can see why I asked about a map. Lacking that, You do, of course, still hold the key... Now you've got my numbers. (Even if I am way off-base.) Excellent riddle.
