Thank you for submitting your item for appraisal. This piece of natural translucient amber of red colour might have been found in Mexico.The surface craquelure seems to be authentic. Most red so called "african amber" is in fact phenolic resin, originaly made in Germany and sold to african countries. Similar pieces of amber sell in the price range listed.
The most expensive amber is baltic amber of opaque yellow colour, which appeals to chinese buyers. I hope you found the information provided helpful to you.
