*Chatham reserves the right to apply a higher cutting fee for any non-standard shape or faceting style that requires custom cutting tools.
** Matching color is an intricate and demanding process that requires a keen eye for detail, extra time on inspection, and an understanding of color theory to assess and compare subtle differences accurately. That is why Chatham charges matching fees to compensate for the expertise. To opt out of the more rigorous process, Chatham can match consistency. This involves a quick visual check to ensure the stones appear consistent and uniform, without the lengthier inspection.
*** Hand selection includes anything that requires additional steps in the order fulfillment process such as specific depth, size, color, and carat weight requirements.
**** Photographs of gemstones serve as a visual reference but do not guarantee the exact color. Variations in lighting, screen settings, and natural differences in each gemstone can affect how the color appears. Viewing the gemstone in person is recommended.
