The Design

The cushion shape gives the ruby softly rounded corners, while the halo introduces a contrasting series of elongated points. Each white accent turns outward, creating the impression of light moving away from the red center. The divided shoulders leave breathing room beneath the halo, so the composition feels dimensional rather than flat. This is the most ceremonial expression in the five-ring holiday edit.

How to Wear It

Ruby Coronation is designed to be the focal jewel. Pair it with quiet earrings or an unadorned neckline for a Christmas celebration, New Year gathering or formal evening. Yellow gold adds warmth beneath the halo, while white gold and platinum give the same design a cooler character. Its festive presence comes from color and shape, not a motif tied to one season.

Made to Order, Chosen by You

Choose your metal and US ring size separately. Each selection preserves the design and the 6.00 ct ruby center specification. The images shown are design visualizations, not images of a finished ring. The selected ruby, final dimensions and construction are reviewed before production; gemstone color can vary with the selected stone, lighting and screen.

For help choosing a size, contact our Jewelry Concierge. An unlisted size, engraving or a design adjustment can be discussed through MISSISSI customization. Feasibility and any change in price or preparation time are confirmed before purchase.

Gemstone Details

The red center is a lab-grown ruby, not a red diamond or a natural ruby. The white accent stones are lab-grown diamonds. The 6.00 ct specification describes the center stone alone, not the combined gemstone weight of the ring. Exact accent carat weight, final metal weight and millimeter dimensions are not stated because they depend on the production specification.

No named laboratory report, ruby color grade or treatment status is promised on this page. If gemstone documentation is important to your choice, ask what is available for the selected stones before ordering.

Preparation and Delivery

Estimated preparation is 15 business days before dispatch, with shipping transit additional. Ask us to review any required arrival date before purchasing. Standard shipping is complimentary to destinations offered at checkout; import duties and taxes are additional unless checkout states otherwise. See the Shipping Policy and Refund Policy for applicable conditions.

Frequently Asked Questions

Is the ruby natural or lab-grown?

It is a lab-grown ruby. The white accent stones are also lab-grown diamonds.

Does 6 ct include the diamond accents?

No. The ring has one 6.00 ct ruby center. Diamond accent weight is separate and is not included in that figure.

Is the halo part of the same ring?

Yes. The sunburst halo and split shoulders form one ring around the cushion-cut ruby; this is not a stack or a multi-ring set.

Which metal and size options are available?

Choose 14K yellow gold, 14K white gold, 18K yellow gold, 18K white gold or platinum. US sizes 4–11 are offered in half-size steps. Select both options before adding the ring to your cart.

Can I request a different size or personal detail?

Contact MISSISSI before ordering. We will review the request and confirm feasibility, specifications, price and timing before purchase.

Is a certificate included?

No particular certificate is specified for this design. Please confirm available documentation for your selected gemstones before ordering.
