We offer one complimentary resizing for engagement rings and non-eternity bands only. This service is available within 7 days of delivery and within ¾ up or down from the original size to maintain the integrity of the ring. Any additional resizing will be subject to a charge.

For purchases and deliveries within the US, we offer complimentary (insured and secure) return shipping both ways along with a professional cleaning and inspection of your ring. Please Contact Us for assistance with resizing.

Please save your original packaging and send it back to us in its original, secure packaging to ensure no damage is done during transit. We are not responsible for damage caused in transit back to us, so it is very important to properly package the ring. 

Please note we cannot resize eternity-set bands (meaning rings that have diamonds set all the way around the band) in order to maintain the integrity of the ring.

All of our lab diamond engagement rings created with 1.00 carat and above center stones are GIA certified. The GIA or EGL certificate comes with the purchase of your lab diamond engagement ring.

Our pink and yellow diamond center stones are not GIA certified unless specified. Currently, most colored diamonds are IGI certified. Please review individual products for certification details or reach out to us for guidance.
