Celestia - Marquise

We believe you shouldn’t have to sift through thousands of stones to find "the one." Our team hand-selects every diamond to ensure it meets our rigorous criteria: Color (DEF) and Clarity (VS+) only. Each stone is IGI certified (with GIA available upon request), ensuring brilliance that’s vetted by the best. To honor the earth as much as the design, every engagement ring is cast in 18k recycled gold or solid platinum—built to be an heirloom from day one.

At Mine & Grown, we believe the journey to your forever ring should be effortless. To ensure a perfect fit from day one, we offer two ways to get it right:

• Before You Buy: Order our complimentary ring sizing kit before you purchase. We’ll ship it to your door so you can find your exact measurement with confidence.
• After It Arrives: We provide one signature resizing (up to 2 EU sizes) on us. Should a more significant adjustment be needed, we may recommend a remake to maintain the ring’s structural integrity.

Each Mine & Grown ring is a custom creation, handcrafted to your exact specifications. Because these pieces are uniquely yours, all custom orders are final sale and cannot be canceled once production begins. We stand behind our craftsmanship—if your ring arrives with a manufacturing defect, we will repair or replace it immediately. To ensure your comfort, we also include one signature resizing (up to two sizes up or down) with your purchase.
