This is a very large Bisbee Turquoise cabochon that would be great for a beautiful pendant, buckle, bracelet or other. It is large but it is fairly thin so you get a lot for your money as its weight is
45 carats and it measures 49mm x 23mm which is very large for Bisbee. You will find very few Bisbee Turquoise cabs this large and when you do they will cost a premium - this one is $15. per carat.
If you like the photo you will love the cabochon in person as it is a medium to deep Bisbee blue with chocolate brown with tan spots of matrix - very unique and collectible.
