Mini Natural Geode Ring Box with Gold Hinge in Ivory Frost White by Aquamarise, opened to show white crystal interior and ring slot

Mini Natural Geode Ring Box with Gold Hinge – Ivory Frost White Edition

$145.00

Product Description

Six clean sides, one smoky heart. This hexagon cut simulated gray diamond engagement ring frames a geometric gray stone in crisp architectural lines, set in solid 925 sterling silver with a bright rhodium finish. It is the ring for the person who finds classic sparkle a little predictable — modern, minimalist and quietly rebellious, with a stormy gray glow you won't see on every hand.

Hexagon geometric cut Smoky gray stone Solid 925 sterling silver Rhodium finish Minimalist design Free velvet gift box

Geometry as a statement

Where most engagement rings chase maximum fire, this one leans into shape. The hexagon — a six-sided honeycomb outline — gives the center a faceted, almost architectural presence, with straight edges that catch light in cool, controlled flashes. It is a deliberately non-traditional look, at home with anyone drawn to clean lines and modern design. If angular cuts speak to you, explore the sharp geometry of our kite cut diamond engagement rings, or keep things pared-back with a solitaire engagement ring.

The center stone

The center is a simulated diamond in a moody gray — a hexagon-cut cubic zirconia, 7.0 mm across, roughly a 1.2 carat presence. Its smoky, storm-cloud tone is what gives the ring its edge: soft and mysterious in shadow, brightening to a silvery shimmer in the light. Gray stones have become a favorite for their understated cool, and this one delivers that look at an accessible price. If you love the smoky, celestial character, our feature on what a salt and pepper diamond is explores the same moody family of stones, and our moissanite versus cubic zirconia guide explains how these bright stones behave.

Accents & band

Sparkling cubic zirconia accents flank the hexagon, adding a fine ribbon of white light that makes the gray center read even cooler by contrast. The band itself is a slim 1.7 mm comfort-fit, smooth against the finger and easy to wear from morning to night.

Solid sterling silver with a rhodium finish

The ring is crafted in solid 925 sterling silver and finished with rhodium — the same precious metal used on fine white gold. That rhodium finish gives the silver a bright, mirror-white luster and adds a protective shield that helps resist tarnish and everyday scratches, so the band keeps its crisp, freshly polished look. It is nickel-free and hypoallergenic for comfortable daily wear.

What it symbolizes

Gray sits between black and white — a color of balance, calm and quiet strength, and a fitting emblem for a partnership built on steadiness rather than show. The hexagon, nature's most efficient shape, has long stood for harmony and structure. For a broader look at how stones have carried meaning across the ages, our essay on the history and symbolism of gemstones is a rewarding read. Prefer a warmer gray with more fire? Compare with our gray moissanite engagement rings.

Frequently asked questions

What is the center stone?

It is a simulated diamond in a smoky gray tone — a hexagon-cut cubic zirconia. It is chosen for its cool, moody color and bright sparkle, giving a distinctive look at an accessible price.

Is the gray color natural to the stone?

The gray is part of the stone's cut and character, giving it a consistent storm-cloud tone that shifts from soft and mysterious in shadow to a silvery shimmer in the light.

How big is the center?

The hexagon measures 7.0 mm across, roughly a 1.2 carat presence, making a clear statement while keeping the overall look sleek and modern.

Why choose a hexagon cut?

The six-sided outline is geometric and architectural, catching light in cool, controlled flashes. It is a favorite for anyone who wants a non-traditional, design-forward engagement ring.

What metal is it made from?

Solid 925 sterling silver, finished with rhodium for a bright white luster and extra protection against tarnish and scratches.

What does the rhodium finish do?

Rhodium is the same precious metal used to finish fine white gold. It gives the silver a mirror-bright shine and a protective layer that keeps the ring looking freshly polished.

How wide is the band?

The band is a slim, comfort-fit design averaging about 1.7 mm, smooth against the finger and easy for all-day wear.

Is it good for everyday wear?

Yes. The cubic zirconia center is hard-wearing, the band is comfort fit, and the rhodium finish protects the silver, so it suits daily wear with a little routine care.

Is it safe for sensitive skin?

It is. The ring is nickel-free and hypoallergenic, comfortable for most sensitive skin.

Can it be engraved?

Yes. Add a personal engraving of up to 16 characters at checkout — a date, initials or a short message. Engraved pieces are final sale, so please check spelling.

Can I upgrade the center stone?

Absolutely. Message us and we can build this setting with a gray moissanite or lab-grown diamond center instead. Most of our designs can be tailored.

What size should I order?

Select your ring size at checkout. If you are unsure or between sizes, contact us for guidance. Resizing is available and starts from a modest fee.

Does it arrive gift-ready?

Every order ships in a free luxury velvet gift box and is backed by our lifetime warranty, ready to give or to propose with.

This ring is beautiful! It has a great amount of sparkle and the simple but unique shape and design is gorgeous. It has some weight to it and is well-made. It’s definitely been a conversation-starter and I love it. I’ll definitely be returning soon for other pieces!

The pictures just don't do it justice, the the pictures are gorgeous. I have had so many compliments!

The ring is stunning, great quality and true to size. I purchased this as a replacement to my engagement ring after the original was lost.

The shipping was seamless and arrived in a beautiful grey, velvet box. The ring is a hit more delicate and slim than some photos may seem; the gems are all clear and well cut. The finish is complete, no flaws even after washing with ring polish and hot water.

It's not a true halo cut, so bear in mind if you plan to stack with multiple bands they should accommodate the angle of the center stone as bands don't quite fit beneath the setting. 🤍💍

It's perfect, thank you! The gray color and shape is so unique. Shipped and delivered super quick too.

This ring is SOOOOO sparkly and gorgeous. Looks exactly like the picture! I’m so excited and satisfied with my purchase. Will be buying more from here. Thank you for this lovely ring!

Absolutely stunning! Just as described. More beautiful than the pictures. Did arrive a few days late but that was due to hurricanes. I love this so much thank you!

Beautiful ring! Shipped relatively fast, and arrived safely. Size was slightly off (about 1/4 size too small) but it still fit.

Beautiful ring. Get many compliments on it. Shipping was fast.

Came quickly and exactly as pictured!

Came in just as pictured! I have small hands and slender fingers so it looks quite large on me! It’s absolutely perfect and beautiful.

Beautiful ring. I 😍 it. I would buy another ring from this seller but my size is sold out. Hopefully my size will be available soon.
Thanks

This ring is beautiful! It looks smaller than the picture but I love it!!!

This is the most beautiful ring I’ve ever seen! It’s absolutely gorgeous and everything I could have wanted and more! Shipping was fast and easy as well! I will definitely be ordering from this shop again!

This ring was absolutely beautiful. I am in love

I was looking all over for a grey hexagon ring. So glad I stumbled upon this one. Fits perfectly, I love this ring!

This ring is the most beautiful thing I’ve ever seen. I instantly fell in love with it, however when I first saw it I didn’t have the funds to pay for it and when I did my size sold out and it broke my heart. I contacted the seller to ask if they do restocks and she was VERY quick and nice and let me know there would be more! I waited and the second I saw it back in stock I bought it instantly! Arrived within days of me ordering it!!! I will 100% recommend this shop and I look forward to getting more pieces in the future! If you’re on the fence about getting anything from this shop, THIS IS YOUR SIGN TO JUST PULL THE TRIGGER AND GET IT!

This ring in gorgeous! The hexagon shape is so different and refreshing, and the stone sparkles under any type of light! It shipped quickly and arrived in a beautiful box.

I love this ring! So beautiful and well made!

Frequently Asked Questions

925 means the metal is 92.5% pure silver, alloyed for strength — pure silver on its own is too soft to hold a stone securely. It is the international standard for fine silver jewellery, and every Aquamarise® piece is stamped 925 inside the band.

Ours is then finished with rhodium — the same precious-metal finish used on white gold. Rhodium is one of the hardest metals used in jewellery and completely non-reactive, which is what gives the ring its bright, cool white surface and keeps it looking that way through daily wear.

Warm water, a drop of mild washing-up liquid and a soft toothbrush around the setting. Rinse well and dry thoroughly with a soft cloth — moisture left sitting on any finish is what dulls it fastest.

Skip the silver dips and abrasive polishing compounds sold for untreated silver: the rhodium finish is doing the work here, and those products strip it rather than clean it. Take the ring off before swimming, cleaning or applying perfume and lotion, and store it dry and separately from harder stones. Our Jewelry Care Guide has the full routine.

For a promise ring, a stacking ring, a travel piece or a first engagement ring, it is an excellent choice — rhodium-finished, bright white, and a fraction of the price of gold. It is the metal most of our customers start with, and the reason our silver engagement rings outsell everything else on the site.

For a ring intended to be worn every day for decades, solid gold and platinum are harder-wearing and hold their value; those are made to order in 3–6 weeks and cost considerably more. Plenty of couples buy sterling now and upgrade at an anniversary. Our Precious Metal Guide compares them side by side.

Measure at home with our Ring Size Chart, or use the Find my ring size link beside the Add to Cart button. If you are between sizes, size up.

If the fit is not right when it arrives, size exchanges are free — send it back within 14 days unworn and we will send the correct size out. That is the whole process: no fee, no forms. Engraved rings are the one exception, as each is cut specifically for you.

On most designs, yes — where engraving is available, a text field appears with the options above. Standard laser engraving is complimentary: up to 16 characters on women’s rings and 25 on men’s, set in Arial, with a selection of symbols included at no extra cost. Custom fonts and symbols are $25 and are arranged before you order.

See the Engraving page for examples. Engraved rings are final sale, so check your wording carefully — we engrave exactly what is entered.
