SEDA GEMS

Ametrine, also known as trystine or by its trade name as bolivianite, is a naturally occurring variety of  quartz . It is a mixture of amethyst and  citrine  with zones of purple and yellow or orange. Almost all commercially available ametrine is mined Bolivia although there are deposits being exploited in Brazil and India

The colour of the zones visible within ametrine is due to differing oxidation states iron within the crystal. The different oxidation states occur due to there being a temperature gradient across the crystal during its formation.

Artificial ametrine can be created by differential heat treatment of amethyst.

Most ametrine in the low price segment can surely be assumed to stem from synthetic material. Since 1994 a Russian laboratory has perfected the industrial production of bicolored quartz crystals that are later irradiated to bring out the typical ametrine colors. Green-yellow or golden-blue ametrine does not exist naturally.

The owner Paul Sedawie is the current president of the Opal Association.All my life i have enjoyed collecting minerals and fossils .I have been opal mining and now have a large opalized fossil collection of museum quality.I enjoy visiting mines in different parts of the world and try to buy direct off the miner or as close to the source as possible to give you the best deals.Natural stones/minerals fascinate me so I don�t stock laboratory made stones.I have a few sites here which I head under the Seda group.I believe that your continued business is my business so I hope you enjoy the amazing array and beauty of nature I have to offer.Best Regards Paul Sedawie We have a retail shop/museum at the Gold Coast Opal and Gem Centre 25 surfers av mermaid waters Qld Australia .4218 open mon to sat 10 to 5

Why are users outbidding themselves?

When a bid is placed, this is the maximum amount a user is willing to bid for the product. Our system will then automatically bid on that users behalf, incrementally increasing the bid to maintain their position as the highest bidder, up to the specified maximum.

When there is an icon indicating 'Auto Bid,' it means our system is actively placing bids for the user based on their maximum bid. This may appear as if users are outbidding themselves, but it's simply a result of the system updating the bid to reflect the users maximum limit.

Audit

The Gemstone Sheriff program allows our members to request an audit on any product, which is completed by an independent Gemologist who assesses the accuracy of the item description and pictures.
