there is a spell that enchants all Sapphire jewelry. it takes cosmic runes and maybe water, not sure. it is a fairly low lvl spell, i think under 20 magic. after that u can enchant emeralds then rubies then diamonds then dragonstones then onyx. those come at higher lvls though
a gold bar and an amulet mold will be needed but you can get one for free at lumbridge F2P
You can craft necklaces in Whiskerton, Cat Isle, but to make seashell or pearl necklaces, you need to talk to Deidra on Hoof Isle.
To enchant sapphire items you need level 7 magic. Have one Water Rune and one Cosmic Rune in your inventory. Click on the spell "Lvl-1 Enchant" in your spell book. Then it will show you your inventory. Click on a sapphire ring, necklace, bracelet or amulet and it will then enchant it (only members of Runescape can enchant rings, necklaces and bracelets).

you craft it
a sapphire from an uncut sapphire by using a chisle on it, and smelt a gold bar into a sapphire necklace.
