This eternity ring in 925 sterling silver is set all the way around with round cubic zirconia that shade from deep navy to sky blue to clear.

Instead of one flat color, the stones run in a repeating gradient - dark blue, mid blue, pale blue, clear - like the sea going from deep water to the shallows. Each stone sits between shared prongs with open sides, so light passes through and the colors glow. At 2.5 mm wide it is slim enough to stack with a plain band or wear alone as a line of color.

  • Full eternity: stones continue around the whole band, so it looks the same from every side.
  • Gradient blue cubic zirconia: navy, sky blue and clear round stones; not sapphire or aquamarine.
  • Slim stacking band: 2.5 mm wide, 1.55 g.
  • Your ring size: US 5 to 9 - pick yours from the Ring Size option on this page.

Frequently asked questions

What metals do you use?

Materials vary by design. Depending on the product, pieces may use 925 sterling silver, stainless steel, copper alloy, brass or leather, with plating or finishes where stated. Check the material details and selected options on the individual product page, or contact us with the item number (SKU) before ordering.

What is your shipping timeline?

Standard shipping takes 7 to 12 business days after dispatch. Personalized items take up to 4 to 7 business days from order to dispatch (1–2 days of processing plus 3–5 days of production; many best sellers ship within 1–2), and other pieces ship within 2 to 3 business days. Check the shipping policy or contact us before ordering for a specific date.

What is your return policy?

60-day quality guarantee on every piece. Non-personalized pieces can be returned within 60 days (80% refund of the item price) or exchanged with no deduction; personalized, moss agate and moissanite pieces are returned only if they arrive faulty. Full policy at /pages/return-exchange.

Is sterling silver hypoallergenic?

Skin reactions vary, and ‘hypoallergenic’ does not mean reaction-free for everyone. Alloy components and plating can vary by product. Check the individual product page and contact us with the item number (SKU) before ordering if you have known metal sensitivities.
