Question 1

Are lab grown diamonds real diamonds?

Accepted Answer

Yes. Lab grown diamonds are chemically, physically and optically identical to mined diamonds — pure crystallized carbon with a 10/10 Mohs hardness. The U.S. Federal Trade Commission officially classifies them as real diamonds. Even trained gemologists cannot tell them apart without specialized laboratory equipment.

Question 2

How much cheaper are lab grown diamonds than mined diamonds?

Accepted Answer

Lab grown diamonds typically cost 70–85% less than equivalent mined stones of the same carat weight, color and clarity. Because we sell direct at wholesale margins rather than through a showroom, our stones work out to only a few hundred dollars per carat — so the same budget buys a dramatically larger and higher-graded diamond than it would at traditional retail.

Question 3

What certification do D'Diamondz diamonds come with?

Accepted Answer

Every diamond we sell is independently graded by IGI, the International Gemological Institute. Each stone ships with its full IGI laboratory report and a matching laser inscription on the girdle, and every report number published on this site can be verified by you directly on the official IGI registry at igi.org before you buy.

Question 4

What quality standards does D'Diamondz enforce?

Accepted Answer

We only stock the top of the grading scale: colorless E and F color grades, VS1 and VVS2 clarity (all completely eye-clean), and Excellent polish and Excellent symmetry on every single stone, with no fluorescence. Every diamond is a Type IIa crystal — the purest and rarest chemical category of diamond. If a stone doesn't meet all of these standards, we don't sell it.

Question 5

Why do some diamonds show a Cut Grade and others don't?

Accepted Answer

IGI issues a formal Cut Grade for round brilliant diamonds only, because the round brilliant is the one shape with universally agreed optical proportions. Fancy shapes — oval, emerald, radiant, pear — are instead graded on polish and symmetry, and every fancy shape we stock grades Excellent on both. It is not a gap in the report; it is how the grading standard works.

Question 6

How fast is shipping, and is it insured?

Accepted Answer

Free FedEx Priority Overnight shipping on every order, fully insured door-to-door with signature required, anywhere in the United States. In-stock diamonds ordered before 2 PM Central Time typically ship the same business day from Texas.

Question 7

What is the return policy?

Accepted Answer

You have 30 days from delivery for a full refund — no restocking fees and no questions asked. Custom-designed settings can be exchanged or remade; loose diamonds are always fully returnable within the window.

Question 8

Does D'Diamondz price match?

Accepted Answer

Yes. Send us any verified written quote from another U.S. retailer for a comparable certified stone and we will beat it by up to 10%. Submit quotes through our Price Match page, by email, or on WhatsApp.

Question 9

Can I create a fully custom engagement ring?

Accepted Answer

Yes. Use our 3D Ring Studio to combine any loose diamond with any setting and metal, or upload an inspiration photo (Pinterest, Instagram, a sketch) and our design team will produce a CAD rendering, usually within 24 hours. Custom rings are typically completed in 2–3 weeks.

Question 10

Is financing available?

Accepted Answer

Yes — 0% APR financing for 12 months is available on approval at checkout, and we also accept all major credit cards via Stripe secure checkout, wire transfer, and split payments arranged through our concierge.

Question 11

Where is D'Diamondz located? Do you serve all of the USA?

Accepted Answer

We are a Texas-based online-first jeweler serving San Antonio, Austin, Houston, Dallas–Fort Worth and all 50 states with free insured overnight delivery. Virtual appointments are available 24 hours a day, 7 days a week — call or WhatsApp +1-210-952-3316, or email contact@ddiamondz.com.

Question 12

Do lab grown diamonds hold up over time?

Accepted Answer

Yes. A lab grown diamond is just as hard and durable as a mined diamond (10/10 on the Mohs scale — the hardest known natural material). It will never cloud, fade or change color, and every D'Diamondz purchase includes a lifetime manufacturing warranty plus a 100% lifetime trade-up credit on loose diamonds.

Question 13

Are lab grown diamonds ethical and eco-friendly?

Accepted Answer

Lab grown diamonds are guaranteed conflict-free — no mining, no displaced communities, and a fraction of the environmental footprint. Growing a diamond in a lab avoids moving roughly 250 tons of earth per carat that traditional mining requires.
