What Is Alexandrite

About Alexandrite

Alexandrite is one of the rarest and most coveted gemstones in the world, famous for its extraordinary color-change: it appears green or blue-green in natural daylight, and shifts to red or purplish-red under incandescent or candlelight. This optical phenomenon — caused by how the stone absorbs light — earned alexandrite the nickname 'emerald by day, ruby by night.' First discovered in Russia's Ural Mountains in the 1830s, fine alexandrite remains extremely rare and is one of the most valuable gems per carat.

Stone properties: Believed to inspire intuition and balance, reminding the wearer that transformation is not loss — it is becoming.

Frequently Asked Questions

Why does alexandrite change color?

Alexandrite contains chromium, which causes it to absorb certain wavelengths of light differently depending on the light source. In daylight (blue-dominant), it appears green; under incandescent light (red-dominant), it appears red or purple.

Is lab alexandrite the same as natural?

Lab alexandrite has the identical chemical composition and color-change properties as natural alexandrite. The difference is origin — one is mined, one is grown. Lab stones are significantly more affordable while offering the same visual effect.

Is lab alexandrite durable for everyday wear?

Alexandrite rates 8.5 on the Mohs hardness scale — excellent for everyday wear. It's one of the more durable colored gemstones available.

Will the color change look different on different people?

The color change is consistent between stones of similar quality, but the intensity can vary. Higher-quality alexandrite shows a more dramatic shift. Lighting conditions — daylight vs. indoor light — make the biggest difference.

Is alexandrite suitable as an engagement ring stone?

Absolutely. Its hardness, rarity, and striking color change make it a meaningful and durable choice for an engagement ring, especially for someone who wants something genuinely unique.

Custom Jewelry FAQ

💍 Getting Started

How do I start the custom ring process?

Email support@starlandus.com with your idea — a description, a reference photo, or even just a vibe. We'll follow up with mock-ups and a quote.

What if I don't know exactly what I want?

That's completely fine. A lot of our best custom work starts with "I kind of want something like this but different." Send us your rough idea — we'll help you shape it.

🪨 Stone Selection

What types of stones can I choose from?

We work with nearly all gemstones. Here's a quick guide by durability (Mohs hardness):
💎 9–10 (Most Durable) — Diamond, Moissanite, Sapphire, Ruby, Alexandrite. Ideal for everyday wear and engagement rings.
💛 7.5–8 (Very Durable) — Topaz, Emerald, Aquamarine, Tsavorite. Great for regular wear, pairs well with protective settings.
💜 6.5–7.5 (Durable with Care) — Quartz Family (Black Rutilated Quartz, Amethyst, Moss Agate, Smoky Quartz, Citrine), Garnet. Suitable for everyday wear with normal care.
💙 5.5–6.5 (Delicate) — Opal, Moonstone. Softer stones — we recommend bezel settings and extra care.
💡 Not sure which stone suits your lifestyle? We'll recommend based on how often you plan to wear it.

Can I pick my own main stone?

Absolutely! We offer a complimentary stone selection service. Simply leave a note saying "Please pick my stone" during checkout, or email us at support@starlandus.com and we'll curate options for you to choose from.

Can I use my own stone in a custom ring?

Unfortunately, we're unable to set customer-provided stones. However, if you have the detailed measurements of your stone, we can create a ring mount (with side stones) designed to fit it perfectly.

📏 Ring Sizing

How do I find my ring size?

You have a few options:
- Most convenient: Visit a local jeweler for a professional sizing — most do it for free.
- Easiest at home: We'll mail you a free ring sizer, just ask!
- Don't stress: Our after-care policy includes complimentary resizing within ±1.5 sizes, so you're covered even if it's not perfect the first time.

🔩 Metal Options

Which metal should I choose — 14K, 18K, or Platinum?

We offer four gold color options: Yellow Gold, Rose Gold, White Gold, and Black Gold. Platinum comes in its natural white finish but can also be plated in other colors upon request.
14K Gold
14K contains 58.5% pure gold alloyed with stronger metals, making it the most scratch-resistant and durable option. It's ideal if you lead an active lifestyle, work with your hands, or simply want a ring that holds up beautifully to everyday wear with minimal maintenance.
18K Gold
18K contains 75% pure gold — noticeably richer in precious metal content. While slightly softer than 14K, it offers a deeper luster and a more luxurious feel. It's the choice for those who value premium materials and don't mind a little extra care over time. If you're investing in something special, 18K gives you that elevated touch.
Platinum
Platinum is the heaviest and most hypoallergenic option. It's naturally scratch-resistant — more so than 18K — and develops a soft patina over time rather than losing metal. Perfect for sensitive skin or heirloom pieces meant to last generations.
