Opal necklace, .925 sterling silver chain, antique style treasure chest box

This is a factory created very colorful opal necklace. It has never been worn. The pendant itself was a plated in 14k white gold, which is just the coating, it’s way too little gold to add any more monetary value to the necklace. The dimensions of the opal itself excluding the pendant’s loop are 10 x 8 mm. With the loop it is 20mm by 10mm. The weight is 1.64 grams for the whole pendant. The pendant also has a rhodium finish to prevent any tarnishing. Instead of the chain it came with, I added a much finer Italian sterling silver diamond cut bead chain necklace “16 inches in length, hypoallergenic, no lead or nickel 1.5mm made in Italy. It’s not the largest nor the smallest silver chain I have, but it is by far the finest in quality. It seems well suited to go with the opal pendant to create a fine looking piece. Lastly, it comes with an antique style treasure chest jewelry box. It’s not really antique. But it looks nice and has a locking mechanism. This item is custom made meaning the pendant, the chain and the wooden chest all came from different companies or artists, but there are not tags, even though it is new and unworn. Please don’t hesitate to ask me any questions
