What's the difference between lab-grown diamonds and natural diamonds?

Lab-grown diamonds have identical physical, chemical, and optical properties to natural diamonds. The key distinction is origin: our diamonds are sustainably created in controlled labs using advanced HPHT/CVD technology, avoiding mining impacts. All stones are certified by IGI/GIA.

Do lab-grown colored diamonds fade over time?

Never. Our lab-created colored diamonds (pink, blue, yellow etc.) get their hues from permanent structural defects or trace elements during growth. They're as color-stable as natural fancy diamonds.

Are lab diamonds cheaper because they're lower quality?

No. Lower cost reflects ethical production efficiency, not quality. Our lab diamonds range from D-color Flawless to vintage-inspired cuts, all with 4C grading reports.

Are lab-grown diamonds acceptable for engagement rings?

73% of millennials actively seek lab diamonds for engagements. Why? They symbolize modern love: conscious, tech-forward, and unbound by tradition.

Do you offer certificates for your lab diamonds?

Yes. All diamonds (lab-grown & natural) will come with a IGI/GIA certificate.

Can I choose my own diamond?

Yes, of course. We will start by showing you some certificates to see the 4Cs, and if you're interested in a salt & pepper diamond, we will show you multiple to choose from as each one of them are one of a kind.

How do I clean my diamond ring at home?

Mix warm water + mild dish soap, soak for 15 mins, gently scrub with a soft toothbrush. Avoid ultrasonic cleaners for salt & pepper diamonds due to natural inclusions.

Why Trust StarlandUS Lab-Grown Diamonds

Every lab-grown diamond we ship comes with a full IGI certificate. Our standard range is D color, VS1 to VVS2 — the top of the lab-grown market, not the entry level. Most of what's sold online sits two to four grades below that, and the price gap you see elsewhere is usually just that difference. Need something else? Everything we sell is fully customizable — the setting, the clarity range, the carat weight. Or skip the setting entirely and just pick a loose stone that fits your budget.

What a Lab-Grown Diamond Is

A lab-grown diamond is a real diamond. Chemically, physically, and optically it is identical to a mined one — same carbon crystal structure, the same 10 on the Mohs scale, same way it handles light. The only difference is how it forms: in a controlled chamber using CVD or HPHT, over weeks instead of billions of years.
Because it is a real diamond, it's graded like one. The 4Cs — cut, color, clarity, carat — apply exactly as they do to mined stones, and the grading is done by an independent lab, not by us.

Our Standard: D · VS1–VVS2 · IGI

· Color: D. The top of the colorless scale. Not G, not 'near colorless' — no yellow tint, even under magnification.
· Clarity: VS1 to VVS2. Inclusions so slight they're invisible to the eye and hard to find even at 10× magnification.
· Certification: IGI on every stone. The International Gemological Institute is one of the world's leading independent gem labs.
We hold to this range because cut only reads properly when color and clarity are high enough to stay out of the way.
Everything else is available by custom order. Setting, color range, clarity, carat, budget — tell us what you need. Start from a loose stone or start from a design: pick the stone first and set it later, or start with the setting and match a stone to it. Every lab-grown diamond we sell can be built to spec. Custom isn't a special request here — it's how we normally work.

Beyond Colorless

Not everyone wants the standard answer. Alongside our colorless range, we carry colored lab-grown diamonds — green, pink, blue, yellow, and deeper fancy tones — for people who never wanted a white stone to begin with. Same certification standard, same clarity range, different intent. Colored stones are customizable too.
If the ring you're designing shouldn't look like everyone else's, start here.

Frequently Asked Questions

Are lab-grown diamonds real diamonds?

Yes. They're identical to mined diamonds chemically and physically — same carbon structure, same hardness, same optical properties. Not simulants, not cubic zirconia, not moissanite. A jeweler with a tester can't tell them apart from mined stones; only a lab with specialized equipment can. That's exactly why certification matters.

What grade will I actually get?

D color, VS1 to VVS2, and the cut grade is usually Excellent. Cut is where the visual difference shows up: a well-cut diamond returns light in three ways at once — brilliance (white light), fire (rainbow flashes), and scintillation (sparkle). A higher-grade stone with a bad cut will look duller than a well-cut stone of lower grade. We don't trade cut quality for a better number on the report. If this range doesn't fit what you need, tell us and we'll match stones to your budget and priorities.

Can I see the IGI certificate before I buy it?

Yes. Every stone ships with its IGI report. If you want to see the certificate for a specific piece before ordering, message us and we'll send it over.

Can I customize to my budget?

Yes — and we do full custom, not just tweaks to the setting. Start from a loose stone or from a design; color, clarity, carat, and budget are all open. If budget is the constraint, there are two ways to go: go smaller and put the money into better cut and clarity, or give up some color or clarity for a bigger stone. Neither is wrong — it depends on what matters more to you. Tell us your budget and how you'll wear it, and we'll give you a straight recommendation.

Why are yours more expensive than the cheapest lab-grown diamonds online?

Because they're not the same stone. The cheapest listings are typically G to J color, VS2 to SI clarity, average cut, and the certificate — if there is one — often comes from a smaller lab or is a self-issued 'appraisal.' Ours are D color, VS1–VVS2, IGI certified, hand-set, and backed by a real service channel. If price per carat is your only measure, we're not the cheapest option, and we'd rather say so than pretend otherwise.

Can anyone tell the difference between lab-grown and mined?

Not by eye, and not with standard jeweler's equipment. The difference is on the certificate, not in the stone — which is the only honest answer to that question. We label origin on every listing.

Do you offer anything besides colorless?

Yes. Colored lab-grown diamonds — pink, blue, yellow, and deeper fancy tones — plus fancy shapes including our signature coffin and kite cuts. Same IGI standard, same clarity range.

How do I care for a lab-grown diamond?

What dulls a diamond is skin oil and hand cream, not wear. Clean it regularly with warm water, mild soap, and a soft brush. Try not to touch the stone's surface directly. On durability: every diamond is a 10 on the Mohs scale regardless of grade, but stones with inclusions near the girdle can chip more easily on a hard impact. A more protective setting gives you extra margin there.

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.
