- The origins are not certified by a laboratory, they are my gemological opinion.
- The photos are taken at 10X, with macro lens, so that are not really visible to the naked eye.
- The pictures are not true to scale, which is why we give you the exact measurements of the stone so you can get a good idea of the size.
- Colors may look different depending on your screen settings.

-Shipping by registered and insured mail (2 -3 weeks)
-Customs charges paid by the buyer
