Ancient Roman General’s Ring

This is an authentic Roman ring depicting a horse. If I remember correctly, this ring would have been owned by either a cavalryman or a general. It is believed to be republic era Rome. It is not gold, but possibly bronze? The stone part is made of I think quartz. I can’t tell the size but it can fit on slightly chubby fingers. It’s in amazing condition and good enough to wear out and about, whether it’s an accessory or for reenactment. Had this looked at by a friend of mine in antiques a few months ago who valued it at $600! I can’t remember all the information he gave me though, so to make up for it I’ve lowered the price. I accept e transfer and cash, and am able to meet up in a public place near me or at my house.
