Question 8

What is the difference between lab-grown and natural diamonds?

Accepted Answer

Nothing chemically — both are pure carbon crystal with identical hardness, brilliance, and structure. The only difference is origin: natural diamonds form over billions of years underground, while lab-grown diamonds are created in weeks using CVD or HPHT technology. Both are graded on the same 4Cs by the same certification labs (GIA, IGI).

Question 9

Are lab-grown diamonds real diamonds?

Accepted Answer

Yes. Lab-grown diamonds are 100% genuine diamond — same crystal structure, same chemical composition, same hardness (10 on the Mohs scale). They are not simulants like cubic zirconia or moissanite. Every lab-grown diamond is certified and laser-inscribed to confirm its origin.

Question 10

What’s the difference between CVD and HPHT diamonds?

Accepted Answer

Both are methods for growing diamonds in a lab, and both produce genuine diamond. CVD (Chemical Vapour Deposition) builds the crystal layer by layer from carbon-rich gas. HPHT (High Pressure High Temperature) replicates natural diamond formation using extreme pressure and heat. CVD is more common for larger, fine-jewellery-grade stones; HPHT is often used afterward to improve a stone’s colour. For buyers, the certificate and 4Cs matter more than which method was used.

Question 11

Are lab-grown diamonds better than natural diamonds?

Accepted Answer

They’re identical in composition, hardness, and brilliance — neither is a “lesser” diamond. House of Diams works exclusively with lab-grown because it means more carat and clarity for the same investment, full sourcing traceability, and a lower environmental footprint. The one tradeoff: the resale market for lab-grown is newer, so resale value is less predictable than natural. For a piece you’re buying to wear, not resell, lab-grown gives real advantages.

Question 12

How much less do lab-grown diamonds cost than natural diamonds?

Accepted Answer

Lab-grown diamonds typically cost 60-85% less than a natural diamond of the same carat, cut, colour, and clarity. The price gap widens as carat size increases, which is why lab-grown is especially popular for larger centre stones.

Question 13

Can you tell the difference between a lab-grown and natural diamond by looking at it?

Accepted Answer

No — not with the naked eye, and not even under most standard jeweller’s loupes. Distinguishing them requires specialized equipment used by gemological labs. This is exactly why certification matters: every diamond we sell comes with a certificate (GIA or IGI) that confirms it as a genuine, lab-grown stone.

Question 14

What does CVD mean in diamonds?

Accepted Answer

CVD stands for Chemical Vapour Deposition — the process used to grow a diamond by building up carbon atoms, layer by layer, onto a diamond seed inside a controlled chamber. It’s the primary method used to grow the diamonds in House of Diams jewellery

Question 15

What does HPHT mean in diamonds?

Accepted Answer

HPHT stands for High Pressure High Temperature — a diamond-growing method that recreates the pressure and heat conditions diamonds form under naturally, compressing carbon into crystal form. It’s also commonly used as a follow-up treatment to improve a CVD-grown diamond’s colour.

Question 16

What are the 4Cs of a lab-grown diamond?

Accepted Answer

The same 4Cs used for natural diamonds — Cut, Colour, Clarity, and Carat — apply identically to lab-grown diamonds, graded by the same standards at the same gemological labs (GIA, IGI). Cut affects brilliance, colour is graded on a scale from colourless to yellow, clarity measures internal and surface imperfections, and carat is the stone’s weight. None of these grading standards change based on whether a diamond is natural or lab-grown.

Question 17

Are lab-grown diamonds as durable as natural diamonds?

Accepted Answer

Yes — completely. Lab-grown and natural diamonds share the exact same crystal structure and score a 10 on the Mohs hardness scale, the highest of any natural material. A lab-grown diamond will wear, scratch-resist, and last exactly the same as a natural one — there’s no durability tradeoff at all.

Question 18

When should I order a diamond gift for Christmas?

Accepted Answer

Order by early November for made-to-order pieces. That allows full production time plus international shipping, with a buffer for delays. Courier networks slow considerably through December, and made-to-order jewellery cannot be rushed without compromising the work. In-stock pieces need less notice, but earlier is always safer than later.

Question 19

Is lab-grown diamond jewellery a good Christmas gift?

Accepted Answer

Yes. Lab-grown diamonds are chemically, physically and optically identical to mined diamonds, graded by the same laboratories against the same standards. The practical advantage for a gift is that the same budget buys a noticeably larger or higher-grade stone. Every piece comes with independent IGI or GIA documentation.

Question 20

What is the best diamond gift for a first Christmas together?

Accepted Answer

A solitaire pendant or a pair of stud earrings. Both suit almost any wardrobe, need no sizing, and can be worn daily rather than saved for occasions. They also carry less weight of expectation than a ring, which matters for a first significant gift.

Question 21

How much should I spend on a diamond Christmas gift?

Accepted Answer

Whatever you are comfortable with — there is no correct amount. What matters more is where the money goes. A well-cut smaller diamond looks better than a larger poorly cut one at any price, so prioritise cut grade over carat weight.

Question 22

What if the size or style is wrong?

Accepted Answer

Read the returns and resizing policy before ordering. International returns and made-to-order pieces are often treated differently from standard stock items, so check both specifically. Most rings can be resized within a range, but eternity and tension settings frequently cannot.

Question 23

Do diamond gifts come with a certificate?

Accepted Answer

Qualifying centre stones come with an independent IGI or GIA grading report. The report documents the 4Cs, confirms the stone is laboratory grown, and carries a number you can verify directly with the laboratory. For a gift, that certificate reassures the recipient as much as it documents your purchase.

Question 24

What diamond jewellery suits someone who wears very little jewellery?

Accepted Answer

A fine-chain solitaire pendant or small stud earrings. Both are low-profile enough to wear continuously without feeling conspicuous, and neither requires any decision about how to style it. Avoid statement pieces for someone who does not already wear them.

Question 25

Can diamond jewellery be gift-wrapped or personalised?

Accepted Answer

Ask before ordering, as presentation varies by piece and by seller. If the gift is being shipped internationally, confirm whether packaging arrives sealed and whether any paperwork showing the price is included in the parcel.

Question 26

When should I order an engagement ring for a Christmas proposal?

Accepted Answer

September or October for a made-to-order ring. That allows design approval, production, international shipping and a buffer for resizing. Ordering in late November leaves no margin — and December is the slowest shipping month of the year.

Question 27

How do I find her ring size without her knowing?

Accepted Answer

Borrow a ring she already wears on the correct finger and measure its inner diameter in millimetres. Alternatively, ask a close friend or family member to find out casually, or measure an existing ring against a printed sizing guide. Do this weeks ahead, not days — it leaves room to correct a mistake.

Question 28

What if I get the ring size wrong?

Accepted Answer

Most rings can be resized within a range, though eternity and tension settings often cannot. If you are uncertain, size up rather than down: a loose ring can be worn on the day and resized afterwards, while a tight one cannot be worn at all. Confirm the resizing policy before ordering.

Question 29

Should I propose with the final ring?

Accepted Answer

Not necessarily. Some couples propose with a simpler ring and design the final one together afterwards. If you are genuinely unsure about her taste, that removes most of the risk from the decision, and it is increasingly common.

Question 30

Is Christmas Day a good time to propose?

Accepted Answer

It depends entirely on whether she would want a shared family moment or a private one. Christmas offers both: a private proposal on Christmas morning gives the moment room to breathe, while proposing in front of family creates a shared memory but removes the chance for a private reaction first.

Question 31

Should I propose in front of family or privately?

Accepted Answer

Privately first is the safer choice if you are uncertain. It gives her the chance to react without an audience, and the celebration with family can follow immediately afterwards. Proposing in front of everyone removes that option entirely.

Question 32

How much should I spend on an engagement ring?

Accepted Answer

There is no correct multiple of anyone’s salary — that idea came from a 1930s advertising campaign, not from tradition. Set a figure you are comfortable with, then optimise the specifications within it. Lab-grown pricing means that figure usually goes considerably further than expected.

Question 33

Can I return or exchange an engagement ring if she does not like it?

Accepted Answer

Check the specific policy before ordering, particularly for made-to-order and bespoke pieces, which are frequently excluded from standard returns. Ask what applies to international orders, and get the answer in writing rather than relying on a general returns page.

Question 34

What is a reasonable amount to spend on diamond jewellery?

Accepted Answer

Whatever you are comfortable with. The old salary-multiple guidance came from advertising, not from any tradition. Decide the number first, then optimise the specifications within it — that produces a better piece than starting from a target carat weight.

Question 35

Is it better to buy a bigger diamond or a better quality one?

Accepted Answer

Prioritise cut quality first, then size. Cut determines how a diamond returns light, so a smaller excellently cut stone visibly outperforms a larger poorly cut one. After cut, size usually matters more to most people than the final grades of colour and clarity.

Question 36

Are lab-grown diamonds cheaper than natural diamonds?

Accepted Answer

Yes, substantially — and the gap widens as carat weight increases. That difference is the main practical reason buyers choose lab-grown: the same budget buys a larger stone, a higher grade, or a more elaborate setting.

Question 37

Does lab-grown really mean I can buy bigger?

Accepted Answer

Yes. Because lab-grown diamonds cost significantly less at equivalent grades, most buyers can move up a size class or a clarity grade for the same total spend. The effect is most noticeable above one carat, where natural diamond pricing rises steeply.

Question 38

Is a certificate necessary at lower budgets?

Accepted Answer

For any meaningful centre stone, yes. Certification is what makes the grades verifiable rather than a seller’s claim. Without an independent report from IGI or GIA, you have no way to confirm what you actually bought.

Question 39

What diamond jewellery holds its value?

Accepted Answer

Very little retail jewellery resells at purchase price, regardless of whether the diamond is lab grown or natural. Buy jewellery to wear rather than as a financial asset. If resale genuinely matters to you, that is a reason to discuss options openly with your jeweller before buying.

Question 40

What should I stop paying for?

Accepted Answer

D–F colour when the stone sits in yellow or rose gold, where the difference cannot be seen. VVS or Flawless clarity when a verified eye-clean VS2 looks identical to the naked eye. And landing exactly on a round carat threshold instead of just beneath it.
