Detailed information about each topic is available by clicking on the links above. Each piece of jewelry is sent off site to be evaluated by an appraiser who is not a Topazery employee and who has earned the GIA Graduate Gemologist diploma as well as the title of AGS Certified Gemologist Appraiser. The gemologist/appraiser's report is included on this page. Diamonds, pearls and colored gemstones are graded by the grading standards as taught by the Gemological Institute of America (GIA). All measurements and carat weights are approximate, unless otherwise noted, and are determined without removing the stones from the mounting. The process of determining when a jewelry piece is made and the period it belongs to is not an exact science. The determination is based on design, materials, hallmarks, signatures, and the manufacturing method. Circa dates and period assignments are made to the best of our abilities. All pearls are cultured unless noted as natural. Platinum refers to all metals in the platinum family and the alloys which are mixed with it -- palladium, platinum/iridium, and platinum/ruthenium and platinum/cobalt. A non-destructive acid scratch test is used to verify the metal in each jewelry piece. A refractometer is used to test gemstones. All gemstones have been treated by accepted industry standards unless noted otherwise. Computer monitors show colors differently; please keep in mind that the actual colors in a jewelry piece may be different from the colors displayed in the website photos. Jewelry photographs are enlarged to show details. To help you determine if a jewelry piece is appropriate in terms of actual proportions that suit your style as well as the statement you want to make, we provide detailed measurements of the piece. Rings are also photographed on a mannequin's hand in a glove size 6. Rings in sizes from 5.0 or smaller are photographed on a mannequin's hand in a glove size of 5.0. Jewelry pieces are pre-owned and have been expertly restored unless otherwise noted as new or antique style. For special ring orders and antique style or reproduction rings which are new, the diamond and gemstone carat weight, color, clarity, gram weight, as well as other jewelry details may vary from the website specifications. If an appraisal is offered with a jewelry piece, the value for the jewelry is based on the range of prices prevailing in the most common and appropriate retail markets on the date the appraisal was completed.
