Product Description

Nerida in white and violet. A 5.5 × 10 mm oval lab-grown white sapphire sits in four prongs inside a kite-shaped frame of engraved leaves, with a round natural amethyst at each of the four points and a split shank that opens into the frame. Solid 925 sterling silver with a rhodium finish.

Lab-Grown White Sapphire Oval Cut, 5.5 × 10 mm Natural Amethyst Accents Engraved Leaf Frame 925 Silver, Rhodium Finish Sizes 4–11

The Design

Nerida is named for the sea nymphs of Greek myth, and this is the pale version: the oval sits north to south in four prongs inside a pointed, kite-shaped frame with leaves engraved into the metal on every side, so the white stone reads as the center of a larger silver leaf. A single round amethyst marks each of the four points of the kite and the frame's edge is beaded with milgrain. The shank splits as it reaches the frame and runs into its two side points, which keeps the frame open and light rather than solid. The same Nerida mount is made in black ruthenium with lab-grown Paraiba spinel, lavender opal and ruby.

Our oval engagement rings guide covers why the cut flatters the hand, white sapphire vs diamond covers how the center compares to a diamond, and vintage engagement rings covers the filigree lane this ring belongs to. For the wider field, non-traditional engagement rings.

The Stones

The center is lab-grown white sapphire, grown as corundum with the same chemistry and 9 Mohs hardness as a mined sapphire, colorless and cut as a 5.5 × 10 mm oval. White sapphire has less fire than diamond or moissanite and a cooler, glassier brilliance, which suits the antique frame. Our sapphire guide covers the stone and the September birthstone guide covers sapphire as a gift.

The four accent stones are natural amethyst, the purple variety of quartz, 7 on the Mohs scale, in a true medium violet. Amethyst is the February birthstone; amethyst meaning and the February birthstone guide have more, and amethyst engagement rings covers the stone in bridal settings.

Metal

Solid 925 sterling silver with a rhodium finish, the bright white platinum-group coating used on white gold. It keeps the silver from tarnishing and gives the filigree a crisp white edge against the purple points.

Care

Sapphire is 9 on the Mohs scale and amethyst is 7, so both suit daily wear and the rhodium finish is the limiting factor. Clean with warm water, mild soap and a soft brush, working the brush through the filigree where lotion collects, then dry before storing. No silver polishing cloths or abrasive compounds, which wear the rhodium thin; avoid chlorine, ultrasonic cleaners and household chemicals for the same reason. Keep amethyst out of prolonged direct sun, which can fade the color over years. Our how to clean sterling silver and engagement ring care guides cover the rest.

Frequently Asked Questions

Is the white sapphire real?

It is lab-grown sapphire: real corundum, chemically and physically the same as a mined white sapphire, grown in a lab rather than dug up. It is not cubic zirconia or glass.

Does white sapphire sparkle like a diamond?

Not quite. White sapphire has less fire than diamond or moissanite and a cooler, glassier brilliance. It reads as a clear white stone rather than a rainbow one.

Are the purple stones real?

Yes. The four accent stones are natural amethyst, one at each point of the kite frame.

How big is the center stone?

5.5 × 10 mm, oval cut, held in four prongs with the length running along the finger.

Is this a birthstone ring?

Two of them. Sapphire is the September birthstone and amethyst is the February birthstone.

Is it hard enough for everyday wear?

Yes. Sapphire is 9 on the Mohs scale and amethyst is 7. The rhodium finish on the silver, not the stones, is the part to protect.

Does the silver tarnish?

Not the way bare silver does. The ring is solid 925 sterling silver with a rhodium finish, which acts as a barrier against tarnish. After years of daily wear the finish can thin, and the ring can be refinished.

What is the ring made of?

Solid 925 sterling silver with a rhodium finish. No brass or base metal.

Can I stack it with a band?

The kite frame sits above the finger with a split shank, so a slim band stacks against the shank on either side; a wide band will sit below the lower point of the frame.

Does it come in other stones?

Yes. The Nerida mount is also made in black ruthenium with lab-grown Paraiba spinel, lavender opal and ruby, each with matching accent stones.

What sizes are available?

Sizes 4 through 11, including every half size.

Can I have it engraved?

Yes. Engraving is available on the inner band, up to 16 characters, and can be added as an option at checkout.

Are the stones ethically sourced?

Yes. All Aquamarise stones are conflict-free and responsibly sourced, and every order arrives in a free luxury velvet jewelry box.

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 jewelry, 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 jewelry 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, one free size exchange per order is included — send it back within 30 days unworn and we will send the correct size out. 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.
