NOTES
- All gems are sent with a certificate.
- The origins are not certified by a laboratory, they are my gemological opinion.
- The photos are taken at more than 10X, with macro lens, so there are inclusions that are not really visible to the naked eye.
- The pictures aren't true to scale, which is why we give you the exact measurements of the stone so that you can get a good idea of the size.
- Colours may look different depending on your screen settings, I try to make them as real as possible
