Obsidian

Obsidian is a naturally occurring volcanic glass. It is formed when felsic lava extruded from a volcano cools without crystal growth. Obsidian has been known since prehistoric times, and has some fascinating properties as well as some important practical uses.

In addition to its use as a gemstone, obsidian has been used in cardiac surgery, as well-crafted obsidian blades have a cutting edge many times sharper than high-quality steel surgical scalpels. In some stones, the inclusion of small, white, radially clustered crystals of cristobalite in the black glass produce a blotchy or snowflake pattern, and this is known in the gem trade as snowflake obsidian.

Excellent prices, excellent gemstones, easy to navigating, at the checkout, only a part of my cart was paid, then I get back to my chart, and the missing gemstones were there, so I pay it.At the end of the day, I did 2 consecutive purchases, paying 2 shippings. But even with that issue, I’m sure that worth it.Thanks!

Fantastic dealer for quality gemstones. Website is easy to navigate, selection is superb, delivery of purchases is prompt. Easy to select incorrect payment options, however.

Me parece que la pagina es muy accesible para la compra y el pago ; solo tengoUna oportunidad de mejora seria que exista la opcion de recoger el pedido directamente en la sucursal de mensajeria porque en ocasiones casi siempre estamos fuera de casa. en general todo muy bien por el momento.Otra opcion de mejora es que existieran cupones de descuento y ofertas especiales , ya que una amiga y yo compramos frecuentemente gemmas para uso personal y a ella le comentaron que no tenian ningun descuento como cliente frecuente , esto lo pregunto previo a hacer este pedido .gracias !

Great service. I understand supply depends on other factors so I don't mind checking back from time to time. I do, however, have a problem with the mobile website trying to sign me up for emails when all I'm doing is a simple search
