Hadar sterling , 9k gold, and retail blue opal ring

Product Name: Hadar sterling , 9k gold, and retail blue opal ring
Handmade, kinda rustic, bold. Interesting ring. Made by an Israeli jewelry company. This ring sells for $279.00. It appears that this particular ring has been given another thick layer of silver, as the originals are as thick as the obvious first layer. Whether Hadar customized this ( I believe they do) or the buyer did, I don't know. But is is for sure there. Photo # 2 shows clearly and magnified., a small chip in the opal. I actually did that myself. It is NOT retail visible to the naked eye. The see thru side on photo #9 is simply the way it's made. I've seen this on other rings by Hadar. This ring weighs 15.70 grams. Size 5 1/2.
