"Promise" Lab-Grown Diamond Pendant Necklace

Stone type, metal, finish, size, and certification details vary by style and are listed on each product page. For lab-grown diamond styles, the diamonds are grown in a laboratory rather than mined.

Metal varies by style and selected variant. Some pieces use sterling silver, while others may use gold, white gold, or platinum options where listed. Review the product page before checkout, and contact us if you have metal sensitivity.

Processing for ready-to-ship items usually takes 1-3 business days. Delivery time depends on destination and selected shipping method. Made-to-order and engraved pieces require longer lead times which are shown on the product page or at checkout.

Size options vary by style. Adjustable rings include the listed fit range, while fixed-size rings should be ordered in your selected size. Contact support@vowmira.com before ordering if you are between sizes or need custom sizing.
