All mined diamonds and gemstones are sourced from reputable US and Canadian vendors who pledge to only supply diamonds traded in accordance with the Kimberley Process. The Kimberley Process is a strict certification system supported by the United Nations ensuring conflict-free diamond trading. Larger individual white diamonds come with a grading report, such as from GIA, GCAL, etc. Smaller white accent diamonds only have the certification written on the original wholesale invoice from our trusted vendor.
In the continual quest for a unique and eco-friendly aesthetic, we also offer recycled and antique diamonds, as well as lab-grown diamonds and moissanite. We work only with reputable US-based companies, who offer the highest-quality lab-grown stones.
All Kristin Coffin jewelry is meticulously handcrafted from the finest materials, to the highest standards of quality. We offer a warranty on the craftsmanship of all jewelry, which covers workmanship defects for 1 year from the date you received it. In the extremely rare event that there seems to a defect with any piece, simply contact Kristin. The warranty excludes coverage for wear and tear, abuse, loss of stones, and theft. The warranty does not cover repairs if the Care & Cleaning guidelines are not followed. If your jewelry becomes damaged through wear & tear, negligence, or beyond the first 1 year, repairs can be done for a fee.
For those situations not related to manufacturing defects, we strongly recommend you purchase your own insurance. Jewelry is commonly insured as a rider on your homeowner's or renter's policy, or via separate companies like Jeweler's Mutual. An insurance policy can protect against loss, theft, and possibly damage due to wear.
