# 1 Lab-grown diamonds are fake.
Nope. Not even a little bit. Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds. They’re not “fakes.” They are diamonds — just grown in a lab, not dug from the earth. If it walks like a diamond, sparkles like a diamond, and tests like a diamond… it’s a diamond.
#2 They don’t last.
Wrong again. Lab-grown diamonds are just as hard (hello, 10 on the Mohs scale), just as durable, and just as eternal as mined diamonds. Your great-granddaughter can absolutely inherit it — and still wear it to brunch.
#3 They’re cheap.
Let’s reframe that: they’re fairly priced. You’re not paying a premium for mining operations, middlemen, or million-dollar markups. Lab-grown diamonds are 30–70% more affordable than their mined twins — without compromising on quality. It’s not “cheap.” It’s just not inflated.
#4 They don’t sparkle the same.
Oh, but they do. Cut, colour, clarity, carat — all the Cs apply. A well-cut lab diamond can out-sparkle a poorly cut mined one any day of the week. (And yes, Coluxe only uses excellent-cut stones. You’re welcome.)

#9 You can’t return or exchange lab-grown pieces.
This one’s just lazy. The rumour that lab-grown jewellery is “final sale” or “non-returnable” is just outdated retail fear-mongering. At Coluxe, you absolutely can. We believe luxury means feeling good — not stuck.
So every piece comes with:
- A flexible return and exchange window
- Easy, no-fuss processing
- Support from our real (lovely) team, not a chatbot maze
Whether you’re rethinking a carat size, gifting instead of keeping, or simply changing your stack — we’ve got you. We want you to wear your diamonds with joy, not buyer’s remorse. Because peace of mind is part of the sparkle.
#10 You still Lab-grown diamonds aren’t certified.
Wrong again. All Coluxe diamonds above 0.30 carats come with full certification from internationally recognised gem labs — the same ones used by traditional fine jewellery houses.
That means:
- IGI or GIA certificates
- Full 4C grading (cut, colour, clarity, carat)
- Transparent provenance and quality markers
Translation:Lab-grown doesn’t mean “uncertified.” It means real diamonds, real credentials, and no shady business. In fact, because lab stones are created in controlled environments, their quality is often more consistent — and their grading more precise. So yes, your Coluxe diamond is 100% legit and backed by paperwork.
One Last Sparkly Truth?
If someone tries to tell you lab-grown diamonds “don’t count,” just smile, flash your Coluxe ring, and let it do the talking. Coluxe. Lab-Grown. Self-Bought. Unapologetically Real.
