A sonnet is fourteen lines held to a strict form — and somehow that discipline is what makes it romantic. The Sonnet follows the same logic: an alexandrite ring in white gold whose elongated, 5.0 x 9.0 mm hexagon-cut stone holds a shifting poem of color inside clean geometric borders, bluish green in daylight and purplish red by lamplight. It is the sleekest silhouette in our alexandrite engagement rings collection.
The elongated hexagon: a rarer geometry
Most hexagon stones are cut equilateral. The Sonnet’s center stone is stretched to 5.0 x 9.0 mm — nearly twice as long as it is wide — so it draws a slim line down the finger the way a marquise or an emerald cut does, while keeping the crisp, faceted corners that make geometric rings feel modern. Approximately 1.3 carats ride on a 1.6 mm band, so the proportions stay graceful rather than heavy. If angular stones are your language, our kite cut alexandrite engagement rings and broader geometric engagement rings are natural next stops.
A stone that will not sit still
The center stone is a lab-grown alexandrite — real alexandrite, grown rather than mined, with the strong color change the species is celebrated for. Daylight and cool white light bring out bluish green and teal; incandescent light and candlelight turn it purplish red, with violet and magenta in the transitions. Because lab growth produces exceptionally clean crystal, the shift is vivid and consistent. Our plain-English explainer on lab-grown vs natural alexandrite covers exactly what the lab origin does and does not change.
Solid white metal, four ways
Choose solid 10K white gold for the hardest, most affordable option; 14K for the most popular balance of durability and gold content; 18K for the richest feel; or platinum — naturally white, densest of all, and hypoallergenic. Each is precious metal through and through. The 10K vs 14K vs 18K karat guide breaks down the differences if you are on the fence.
The supporting cast
Accent stones frame the center in your choice of moissanite (D color, VVS1 clarity) or natural diamond (G/H color, I1 eye-clean clarity, conflict-free). Moissanite is itself a real lab-grown gemstone with more fire than diamond — if that surprises you, read is moissanite a lab-grown diamond for the full story. Either choice keeps the focus where it belongs: on the color-changing center.
For the one who contains multitudes
June’s birthstone and the gem of the 55th anniversary, alexandrite has long stood for balance between two natures — day and night, logic and feeling. A named design with a literary streak, the Sonnet suits someone who appreciates structure on the surface and depth underneath. It works as an engagement ring, a promise ring, or a milestone gift that reads differently at every dinner table.

Sizing & care
Choose your size from the drop-down menu — and because sizing tools vary between jewelers by as much as half a size, double-check yours against our ring size guide first.
Alexandrite rates 8.5 on the Mohs scale, so the Sonnet is built for daily wear. Warm water, mild soap, and a soft brush keep the stone bright; dry with a soft cloth and store the ring apart from diamonds and other harder gems. Ships free across the USA in a luxury ring box.
Frequently asked questions
Why is this ring called the Sonnet?
Like the poem, the design pairs strict structure with romance: an elongated hexagon’s clean geometric lines holding a stone whose color reads differently every time the light changes. The name marks it as one of our named signature designs.
Is the center stone genuine alexandrite?
It is lab-grown alexandrite — real alexandrite by chemistry, hardness (8.5 Mohs), and optics, created in a lab instead of mined. The lab origin is what makes a stone with this strong and clean a color change attainable.
What is an elongated hexagon cut?
A hexagon stretched along one axis — here 5.0 x 9.0 mm, nearly twice as long as wide. It keeps the hexagon’s faceted corners but wears more like a marquise or emerald cut, drawing a slim line down the finger.
What colors will I see, and when?
Bluish green to teal in daylight and under cool white bulbs; purplish red under incandescent light and candlelight; violet and magenta in mixed lighting. The change is a property of the stone itself and happens every time the light source changes.
Does the elongated shape flatter the hand?
Yes — elongated stones visually lengthen the finger, which is why marquise and emerald cuts are perennial favorites. The Sonnet gives that effect with a more unusual, geometric personality.
How does the Sonnet differ from a standard hexagon alexandrite ring?
A standard hexagon alexandrite ring carries an equilateral stone — ours measure 7.0 x 7.0 mm. The Sonnet’s 5.0 x 9.0 mm stone is elongated, so it reads sleeker and more linear on the hand while carrying slightly more carat weight at approximately 1.3 ct.
Which metal should I choose?
All options are solid: 10K white gold is hardest and most affordable, 14K is the most popular balance, 18K carries the most gold, and platinum is the densest and naturally hypoallergenic. Pick platinum for sensitive skin, 14K for all-around value.
Are the moissanite accents real gemstones?
Yes. Moissanite is a real lab-grown gemstone (silicon carbide) rated 9 on the Mohs scale, with more fire than diamond. It is not a fake diamond — it is its own gem. Ours are D color, VVS1 clarity.
What are the diamond accents like?
Natural, conflict-free diamonds in G/H color and I1 eye-clean clarity — bright white sparkle with the traditional pedigree, rated 10 on the Mohs scale.
Can this be a daily-wear engagement ring?
Yes. At 8.5 Mohs, alexandrite is harder than nearly every colored gemstone, and both solid white gold and platinum are proven everyday metals. Remove it for abrasive work and it will keep its looks for the long haul.
Is engraving available?
Complimentary engraving of up to 16 characters is included with every Sonnet — a date, a name, or a line of your own.
How long is production?
The ring is made to order; please allow 3–5 weeks for handcrafting. Requested modifications may change the timeline and pricing.
How do I get my ring size right?
Measure with our ring size guide at aquamarise.com/pages/find-your-size before ordering. Different jewelers’ sizers and mandrels can disagree by up to half a size, so one careful measurement saves a remake.
Can I customize the gemstone or add an appraisal?
Yes — contact us for a custom quote on a different gemstone. An optional appraisal is available from the drop-down menu; its cost is non-refundable once the appraisal work is performed.
✨ Production time

AVAILABILITY
Engraving is offered on most — though not all — designs. If it is available for this ring, an engraving field appears with the options above.

Frequently Asked Questions
Every ring on this page is made in solid gold or platinum — never plated, never gold-filled. Solid gold comes in 10K, 14K and 18K across yellow, white and rose; our platinum is 95% pure, naturally hypoallergenic, and white the whole way through. Available metals vary by design and are listed in the selector above. Our Precious Metal Guide explains how each one wears.
Side by side and brand new, the two look almost identical. The difference shows up over years of wear.
White gold is a gold alloy finished with rhodium for brightness. It sits lighter on the hand and costs less, and the rhodium finish is refreshed every few years to keep it crisp.
Platinum is white all the way through, so there is no finish to renew. It is around 40% denser — noticeably weightier — and over time develops a soft matte patina that many people prefer. It can be polished back to a high shine whenever you like.
Our Platinum vs Gold guide compares durability, cost and upkeep in full.
Solid gold is gold throughout — alloyed for strength, but the same metal at the surface as at the core. Gold vermeil is sterling silver with a layer of gold applied over it, which thins with wear and needs replating to stay bright. Rings on this page are solid gold or platinum only. Our Precious Metal Guide sets out where each makes sense.
Neither tarnishes. Gold and platinum are two of the most stable metals used in fine jewelry, and both hold their color indefinitely. Platinum does develop a satin patina as it is worn — that is surface texture rather than damage, and it polishes out at any time. Warm water, mild soap and a soft brush is all either metal asks for; see our Jewelry Care Guide.
Nothing on this page is pulled from a shelf. Each solid gold and platinum ring is cast, set and finished for your order, which takes 3 to 6 weeks depending on the design — pavé settings, custom sizing and engraving sit at the longer end. Shipping is added once your ring is finished, and paying for faster shipping speeds up transit only — it does not shorten production. Full timings are on our Shipping & Delivery page.
Use the Size Chart linked beside the Add to Bag button, or our full Ring Size Chart. Because these rings are made to order, we cut your size from the start rather than resizing a stock band — so measure carefully. Your first resizing is free if it is still not right. Most designs can be adjusted, though eternity bands and rings with stones set the whole way around usually cannot.
On most designs, yes — if engraving is available for this ring, a text field appears with the options above. Standard engraving is complimentary: up to 16 characters on women’s rings and 25 on men’s, set in Arial, with a small selection of symbols included. Custom fonts and symbols are $25 and are arranged before you order. See the Engraving page for what is possible. Engraved rings are final sale.
Returns and exchanges are accepted within 14 days of delivery on unworn rings in original condition. Because solid gold and platinum rings are made to order, they are subject to a restocking fee, and engraved pieces are final sale. Full terms are on our Returns & Refunds page. Every ring is also covered by our lifetime warranty against manufacturing defects.
