Masonic Cufflink Moon and star ruby colored stone

Description

I offer free shipping. I use the USPS. If you want an alternative service or priority shipping when the item weighs less than a pound, you will have to ask for it and pay for additional services.  Shipping time frames have changed.  First class is slowing down, and this is out of my hands.  So, if you want to faster, you have to pay for it.  Sorry.
I ship books MEDIA MAIL, NOT FIRST CLASS OR PRIORITY.  Same idea applies: If you want your book faster, you must pay additional fees.
It might be gold filled or plated, but has wear to gold color when I look at it with a jeweler's loupe.  I can't find another one on eBay, or anywhere else.  Sold with wear.  Could be a ruby?
