Why You Can Trust StarlandUS Lab Colored Diamonds

Stone Properties

Color as a statement, not a decoration — for those who never needed permission to stand apart.

Every stone is Fancy Intense or Fancy Vivid, VS1 or above. Every stone comes with an IGI certificate. And every stone is chosen by you — not for you.
Lab-grown fancy color diamonds are real diamonds in every sense: the same carbon crystal structure, the same 10 on the Mohs scale, the same optical fire. The color comes from trace elements or structural conditions introduced during growth — the same color mechanisms that give natural fancy color diamonds their hue, only without the millions of years. Ours range across pink, green, blue, yellow, and champagne — and because saturation varies from stone to stone, we don't sell from a fixed catalogue. We show you real stones that match what you're after, and nothing goes into production until you're happy with the one you've chosen. If you'd like to move up to a natural diamond, tell us — we hold a substantial reserve of natural stones and can match what you need.

Frequently Asked Questions

How to Choose a colored Diamond?
Start with color. Fancy color stones are held to the same 4Cs as white diamonds — color, clarity, cut, and carat weight. The full color scale, lowest to highest, runs: Faint, Very Light, Light, Fancy Light, Fancy, Fancy Intense, Fancy Vivid, Fancy Deep, Fancy Dark — nine grades in all. Only Fancy Light and above carry the word Fancy on the report, and that is what makes a stone a true fancy color diamond; Faint, Very Light, and Light are just a tint, and the trade does not call them fancy color. We work in Fancy Intense and Fancy Vivid — the better color, and the better optical effect you can actually see.
Carat speaks for itself: the bigger the stone, the more it sparkles and the better the color reads — and the more it costs per carat than a smaller stone of the same grade.
Then clarity. Colored stones are graded on the same GIA clarity scale as white ones — FL, IF, VVS1–VVS2, VS1–VS2, SI1–SI2, down to I1–I3. We work at VS1 or above: eye-clean from every angle, which also gives the stone better overall light performance.
Cut carries no official grade on a colored stone. What we do provide is a stone cut to proportion: no see-through window in the middle, no dead dark patches when you tilt it, and a shape that holds color rather than washing it out.
All of these parameters — color grade, clarity, certification — can be confirmed on the certificate.

Are your colored diamonds lab-grown?
Yes — every fancy color stone on this page is lab-grown and IGI-certified. Chemically, physically, and optically identical to natural fancy color diamonds, with the same brilliance and durability, at a more accessible price point — and with a far lighter footprint on the planet. If you'd like to upgrade to a natural fancy color diamond, just get in touch.

Which colors do you offer?
Our fancy color range covers pink, green, blue, yellow, and champagne — the last also known in the trade as desert diamond, running from light honey to deep cognac. Intensity varies from soft pastel to vivid and intense. Before production starts, you can select your stone: we show you what's available in that range, and nothing is made until you've confirmed it.

Do you take custom orders?
Yes — from the stone itself to the finished design. Tell us the color, size, and setting you have in mind and we'll source or cut to it. Reach out and we'll talk through what's possible.

Why choose lab-grown over natural fancy color?
Natural fancy color diamonds are genuinely rare — the majority of mined stones never qualify as fancy color at all — and that rarity is reflected in what they cost. Lab-grown fancy colors offer the same beauty, the same IGI certification, and the same physical properties, at a more accessible price point. That's what makes vivid and intense color a realistic choice rather than an occasional splurge.

Is a colored diamond as hard and durable as a white diamond?
Yes. All diamonds, regardless of color, rate 10 on the Mohs hardness scale. Fancy color stones are equally durable and equally suited to everyday wear.

Do lab-grown colored diamonds fade over time?
The color is set into the stone itself — it won't wear off or wash out the way a coating would. Our colored stones are finished with post-growth treatment to reach their final hue, which is standard practice for lab-grown color and is stated openly on every certificate we issue.

Are lab diamonds cheaper because they're lower quality?
No. Lower cost reflects production efficiency, not quality. Every stone we sell is VS1 or above, at Fancy Intense or Fancy Vivid, with a grading report to prove it.

Are lab-grown diamonds acceptable for engagement rings?
Increasingly, they're the default choice. Lab-grown stones symbolize a different set of values — considered, traceable, and unbound by tradition. We've watched the shift move from early adopters to mainstream buyers over the last few years.

Do you offer certificates?
Yes. Every diamond we sell — lab-grown or natural — comes with an IGI or GIA certificate.

Can I choose my own diamond?
Yes. Every fancy color diamond is unique in tone and saturation, so we'll show you several to choose from.

How do I clean a fancy color diamond ring at home?
Warm water, a drop of mild dish soap, a 15-minute soak, then a gentle scrub with a soft-bristled toothbrush. Rinse and pat dry. Skip ammonia-based or strongly alkaline cleaners. An ultrasonic cleaner is safe for the diamond itself — ours are VS1 or above, so there are no inclusions for vibration to reach — but it is not safe for every metal or setting: skip it on plated finishes (gold-plated, gold vermeil, black rhodium) and on pavé or micro-pavé, where vibration wears the plating faster and can work small stones loose.

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.
