. STONES FROM N6 TO N9 ARE SOLID OPALS, THE REST ARE OPAL DOUBLETS. THE BASE BODY TONE GUIDE REFERS TO THE DARKNESS OR LIGHTNESS OF THE OPAL. THE ONLY DETERMINING FACTOR OF BODY TONE, IS THE FRONT FACE OF THE STONE. THE BUYER SHOULD IGNORE THE MATERIAL ON THE BACK AND THE PLAY OF COLOUR AND BRIGHTNESS OF THE STONE.

**PLEASE NOTE THE BODY TONE GUIDE IS NOT A BRIGHTNESS CHART IE. TWO SIMILAR STONES MAY HAVE THE SAME LEVEL OF BRIGHTNESS BUT HAVE TWO DIFFERENT "N" RATINGS.

The Seda Opal Story
Paul Sedawie started mining at the Four mile field in Lightning Ridge in 1986 with his first partner Bob Young. It took them 6 months to find a decent stone and this experience gave me a healthy respect for the stone and how hard it is to find. The Seda Opal company was incorporated in 1994. We are a member of the Australian Opal and Gem Industry Association .we and . Seda Opals is an abbreviation from our surname Sedawie. The business is mainly wholesale and it is through this site that we can bring the opal fields direct to you. If you don't really like anything, return it for a no questions asked refund or swap it for other stock. You will also find us as the trade shows in Tuscon and Denver. We also send sales staff to some Europe and Asian countries. Our aim is to offer a realiable, friendly service providing good value for your money. Your continued business is our business. All the best. Paul Sedawie and staff.
