Alexandrite Engagement Rings (Lab Grown)

Why Choose an Alexandrite Ring?

Alexandrite is one of the rarest and most fascinating gemstones in the world, prized for its extraordinary colour-changing properties. In natural daylight, an alexandrite gemstone displays rich teal and green hues, while under incandescent light it transforms to reveal shades of purple and reddish pink. This captivating phenomenon, known as the alexandrite effect, makes it one of the most sought after gemstones for engagement rings and fine jewellery. Alexandrite rings for women are an increasingly popular choice for those who want something truly distinctive.

First discovered in Russia's Ural Mountains in the 1830s and named after Tsar Alexander II, alexandrite quickly became a symbol of good fortune and nobility. Natural alexandrite is exceptionally rare, which is why lab grown alternatives have become the preferred choice for couples who want this remarkable colour-changing stone without the scarcity premium. Our Chatham lab grown alexandrites are chemically, physically and optically identical to mined stones, delivering the same mesmerising colour change at a more accessible price point.

Real Alexandrite vs Lab Grown Alexandrite

A question we hear often is whether a lab grown alexandrite qualifies as a real alexandrite ring. The answer is yes. Lab grown alexandrite shares the same chemical composition, crystal structure and physical properties as its natural counterpart, including the defining colour change.

Genuine alexandrite rings from our collection are created using Chatham's controlled growth process, replicating natural conditions to produce a real alexandrite stone with exceptional clarity and a strong, vibrant colour shift. Whether described as lab created alexandrite, synthetic alexandrite or lab grown, the result is a genuine alexandrite gemstone ring that is identical to mined specimens in every measurable way.

Alexandrite Rings in Gold and Platinum

The metal you choose for your alexandrite ring plays an important role in how the stone's colour change is displayed. Platinum and white gold settings provide a cool, contemporary backdrop that highlights the blue-green tones alexandrite shows in daylight, while an alexandrite gold ring in yellow gold creates a warmer contrast that draws out the stone's reddish purple shift under incandescent light. Rose gold offers a romantic middle ground, complementing both colour states beautifully.

At Lily Arkwright, all our alexandrite rings are crafted in either 950 platinum or 18ct gold, including yellow gold, white gold and rose gold options. Every setting is hallmarked and certified in accordance with the Hallmarking Act 1973, ensuring the quality and purity of the precious metal matches the exceptional standard of the gemstone it holds.

Alexandrite and Diamond Ring Designs

For those who love the interplay of colour and sparkle, our alexandrite and diamond ring designs combine a colour-changing alexandrite centre stone with accent diamonds on the shoulders or in a halo setting. An alexandrite diamond ring offers the best of both worlds, with the alexandrite providing dramatic colour and the diamonds adding brilliant fire. All accent diamonds in our collection are conflict free natural diamonds graded G/H colour and SI clarity.

Unique and Custom Alexandrite Ring Designs

Alexandrite has a natural affinity with bespoke and vintage inspired designs. The stone's heritage, stretching back to 19th century Russian royalty, lends itself perfectly to ornate settings featuring milgrain detailing, art deco influences and intricate shoulder work. Our collection includes unique alexandrite rings that reference these classic design elements while maintaining a modern standard of craftsmanship. For those seeking something truly one of a kind, our bespoke design service can create a custom alexandrite engagement ring or custom alexandrite jewellery tailored to your exact vision. Whether you want a handmade alexandrite ring with a specific setting or a completely original design, our team can bring your ideas to life.

The Colour-Changing Magic of Alexandrite

What makes alexandrite so special is its ability to display different colours depending on the light source. In daylight or fluorescent lighting, the stone appears teal, blue-green or sometimes with hints of yellow. Move it under warm incandescent light and the same alexandrite stone reveals rich purple, reddish pink and even deep burgundy tones. The most prized alexandrites exhibit a strong, dramatic shift between these two states.
Our Chatham lab grown alexandrites are specifically cultivated to maximise this colour change effect. Each stone is precision cut to optimise light return and enhance the visual transition between colour states. This attention to optical performance ensures every alexandrite ring from Lily Arkwright delivers the full spectacle this remarkable gemstone is known for.

Alexandrite Ring Price Guide

Natural alexandrite is one of the most expensive gemstones in the world, often exceeding the price of diamonds of comparable size due to its extreme rarity. Fine quality natural specimens can command thousands of pounds per carat, and natural alexandrite rings with a strong colour change in larger sizes are extraordinarily difficult to source.

Lab grown alexandrite offers the same beauty and properties at a significantly more accessible price point. At Lily Arkwright, our alexandrite engagement rings and alexandrite rings for sale are designed to deliver outstanding value without compromising on quality. The price of your ring will depend on the carat weight, cut, metal choice and setting style. Our team is always happy to discuss options and help you find the right balance of size, setting and budget.

Frequently Asked Questions

How much is an alexandrite ring worth?

The value of an alexandrite ring depends on whether the stone is natural or lab grown, along with its carat weight, colour change intensity and clarity. Natural alexandrite is exceptionally rare and can be worth thousands of pounds per carat for fine specimens. Lab grown alexandrite offers the same chemical and optical properties at a fraction of the cost, making it accessible to a much wider audience. At Lily Arkwright, our lab grown alexandrite rings start at an approachable price point while still delivering exceptional colour change and brilliance.

Is alexandrite suitable for an engagement ring?

Yes. Alexandrite scores 8.5 on the Mohs hardness scale, making it one of the harder gemstones available and well suited to daily wear in an alexandrite stone engagement ring. It sits just below sapphire (9) and diamond (10) in terms of hardness, meaning it resists scratches effectively. With sensible care, an alexandrite engagement ring will maintain its beauty for a lifetime.

How do I tell if my alexandrite is real?

The defining characteristic of genuine alexandrite, whether natural or lab grown, is its colour change. A real alexandrite will shift from green or teal tones in daylight to purple or reddish pink under incandescent light. Imitation stones made from synthetic corundum or glass may show some colour variation but lack the distinct, dramatic shift of true alexandrite. Every Chatham lab grown alexandrite from Lily Arkwright comes with a certificate of authenticity confirming it is a genuine alexandrite gemstone ring.

Who cannot wear alexandrite?

There are no restrictions on who can wear alexandrite. In some cultural traditions, certain gemstones are associated with specific astrological signs, and you may find advice online suggesting alexandrite is best suited to particular birth months or star signs. From a practical standpoint, alexandrite is durable enough for everyday wear by anyone. As the birthstone for June, it holds special significance for those born in that month, but alexandrite rings for women and men alike are equally beautiful and appropriate for anyone drawn to this unique colour-changing stone.

Is alexandrite an expensive stone?

Natural alexandrite is among the most expensive gemstones in the world due to its extreme rarity. High quality natural alexandrite rings with a strong colour change routinely sell for more per carat than diamonds. Lab grown alexandrite, however, makes this extraordinary gemstone accessible without the rarity premium. Our Chatham lab created alexandrite rings deliver the same remarkable colour change and physical properties as mined stones, offered at a price that reflects the sustainable and controlled production process.

Can I get a matching alexandrite wedding ring?

Yes. Lily Arkwright offers a selection of wedding bands designed to pair beautifully with our alexandrite engagement rings. If you would like alexandrite stones set into your wedding band, our bespoke alexandrite jewellery service can create a custom piece to match your engagement ring perfectly.
