Vintage Diamond Certification



With each purchase, T&H will provide an independent insurance appraisal for the entire piece. Additionally, each center diamond over 0.25ct in every T&H ring has been certified by an independent laboratory. Together these documents can be used to insure your ring with your insurance company so that it will be covered if anything happens to it.

Every center diamond over 0.25ct in a Trumpet & Horn ring has been certified by an independent gemological laboratory. Unless stated otherwise, it has been taken out of its setting and examined properly by the lab. By doing this, the carat weight stated for each center stone is exact. However, the weights of most of the diamonds and gemstones surrounding each center stone have been determined while still in the setting in order to preserve the integrity of the ring, and are therefore approximate. If any side stones have known weights, it will be noted in the ring’s description.

If a Trumpet & Horn ring has a colored gemstone in the center (instead of a diamond), it has also been taken out of the setting (unless otherwise noted) and examined by an independent laboratory to determine if any treatments have been done to enhance color, stability, or clarity. These rings will come with a separate report that states any findings. Every Trumpet & Horn ring with a center diamond over 0.25ct comes with a full certification from EGL or GIA, as well as an independent appraisal from a graduate gemologist/certified appraiser for insurance purposes.



Each Trumpet & Horn ring includes an estimated date of original manufacture and associated decorative era in its description. These are determined to the best of our ability based on the ring’s materials, methods of manufacturing, overall design, signatures/engravings, lapidary techniques, and technological developments. We have an extensive reference library to categorize and date rings to the best of our ability, but dating and era attributions are not an exact science, as decorative periods often overlap and borrow influences from one another. Based on our extensive knowledge, reference materials, and experience in the vintage/estate industry, each date of original manufacture and decorative period is estimated to the best of our ability, but is not exact or guaranteed unless stated in the official certification that accompanies each ring.
