01

Diamonds

Are lab-grown diamonds real diamonds?
Yes. Lab-grown diamonds have the same crystal structure and the same chemical, physical and optical characteristics as mined diamonds. The difference is how and where they are created.
Are your diamonds certified?
We offer independently graded lab-grown diamonds and provide the relevant grading report where applicable. Certification details are shown with the diamond or can be confirmed with our team before purchase.
Can you help me choose a diamond?
Yes. Tell us your preferred shape, approximate carat size, budget and any specifications you are considering. We can help you compare options based on cut, proportions, color, clarity and overall appearance.
Where do your diamonds come from?
We work with established lab-grown diamond suppliers and focus on transparent sourcing, traceability and consistent quality standards. If you need information about a specific stone, contact us before ordering.
Can I see a diamond before I buy it?
For selected diamonds, we may be able to provide additional images, videos or grading information before you decide. Contact us with the diamond reference or specifications you are interested in.

02

Rings & Sizing

How do I find my ring size?
Use our Ring Size Guide to measure an existing ring, check your finger circumference or compare international ring sizes. For important purchases, we recommend measuring more than once.
What should I do if I am between two sizes?
A slightly larger size is generally more comfortable than a ring that is too tight. Band width and knuckle size also affect fit, so contact us if your measurement falls directly between sizes.
Do wider bands fit differently?
Yes. Wider bands usually feel more snug than narrow bands because more metal sits against the finger. You may need slightly more room for a broad wedding band.
Can my ring be resized?
Resizing depends on the design, setting and amount of adjustment required. Full eternity bands and some intricate pavé or custom designs may have limited resizing options. Contact us before ordering if sizing is uncertain.
How can I find someone else's ring size?
If possible, borrow a ring they already wear on the intended finger and measure its inner diameter. A close friend or family member may also be able to help discreetly.

03

Custom Jewelry

Can you create a ring from my own idea or reference?
Yes. Send us your reference image, sketch or description together with your preferred diamond, metal, size and approximate budget. We can review the idea and advise on the next step.
What can I customise?
Depending on the design, you can customise elements such as diamond shape, proportions, setting style, metal, band width, finishing and selected personal details.
How do I request a custom quotation?
Contact us with your design reference and requirements. The more detail you provide, the more accurately we can assess feasibility and prepare a quotation.
Will I see the design before production?
For custom projects that require CAD development, design approval is normally part of the process before final production begins.
How long does custom jewelry take?
Timing depends on design complexity, diamond sourcing and production. We will provide an estimated timeline once the design and specifications are confirmed.

04

Orders & Delivery

How can I track my order?
Once your order has been dispatched and tracking information is available, you can follow the shipment through your order status page or our Track Your Order page.
Do you ship internationally?
Yes. We ship to many international destinations. Available shipping methods, delivery timing and any destination restrictions are shown during checkout or can be confirmed with our team.
Will I need to pay import tax or customs duty?
Import taxes, VAT, GST and customs charges depend on the destination country and local rules. Use our Tax & Duties Calculator for an estimate before ordering.
Can I change my delivery address after ordering?
Contact us as soon as possible. Address changes may be possible before dispatch, but we cannot guarantee changes once an order has entered shipment processing.
I haven't received my order confirmation. What should I do?
Check your spam or junk folder first. If you still cannot find the confirmation, contact us using the email address entered at checkout.

05

Returns & Warranty

Can I return my order?
Return eligibility depends on the item and whether it was customised or made specifically for you. Please review our Returns Policy before sending anything back.
Can customised jewelry be returned?
Custom, personalised and made-to-order pieces may have different return conditions from standard items. Contact us before purchase if you are unsure about the return eligibility of a specific design.
Do your pieces include a warranty?
Warranty coverage depends on the product and the nature of the issue. If you believe there is a manufacturing problem, contact us with your order number and clear photographs so we can review it.
What should I do if my jewelry is damaged?
Stop wearing the piece if further damage could occur. Contact us with your order details and photographs, and we will advise on the available repair or service options.

06

Payment

What payment methods do you accept?
Available payment methods are displayed securely at checkout and can vary depending on your country, currency and Shopify market.
Can I shop in my local currency?
Where enabled, Shopify Markets displays supported local currencies according to your selected market. Your final checkout currency will be shown before payment.
Can I use an Efi & Co Gift Card?
Yes. Enter the valid Shopify gift-card code at checkout. Any remaining eligible balance stays on the gift card for future use.
Is payment secure?
Payments are processed through Shopify's secure checkout environment and the payment methods enabled for your market.
