Authenticity, antiquity, decorative periods, vintages and or circa dating are determined to the best of our ability based on materials incorporated, methods of manufacture, design, hallmarks and signatures, lapidary techniques, technological developments and consultation of our extensive reference library and materials. Dating and period attributions are not an exact science as decorative periods frequently overlap and borrow influences from one another.
Some of our pieces are mounted in a way that makes it difficult to determine a precise stone’s grading. Diamonds and colored gemstones that cannot be removed from their vintage settings without harm to the piece are evaluated in their mountings using industry-standard measurements and formulas. Jewelry descriptions and all carat weights stated represent approximates. Mounted stone(s) is/are graded only insofar as mounting permits observation. All diamonds shown on our website are natural, untreated diamonds.
Most colored gemstones (i.e. rubies, sapphires, and emeralds) are commonly treated to enhance colour or clarity. This has not been researched for this specific item.
We cannot guarantee that the color you see matches the item color, as the display of color depends, in part, upon the type of computer monitor used to observe the image.
