02 · USING OUR STORE
By using this website or placing an order, you confirm that you are legally capable of entering into a contract in your jurisdiction, or that you have any consent required by law.
You must not misuse the website, interfere with its security or operation, introduce malicious code, attempt unauthorised access, or use our website, designs or content for unlawful purposes.
We may restrict access, cancel a fraudulent transaction or take other reasonable steps where necessary to protect customers, Efi & Co or the operation of the store.
03 · ORDERS
When you submit an order, you are offering to purchase the selected item subject to these Terms. Receipt of an automated checkout message does not necessarily mean that we are able to fulfil every specification.
Check the item, diamond, metal, size, engraving, quantity and delivery details before paying.
Completing checkout submits your request to purchase the selected product.
We may review payment, stock, diamond availability and any requested customisation.
For made-to-order and bespoke pieces, sourcing or production may begin shortly after acceptance.
We may decline or cancel an order before fulfilment where payment cannot be authorised, a product or diamond is unavailable, there is an obvious pricing or listing error, we suspect fraud, or we cannot reasonably produce the requested specification. If payment has already been taken for an order we cannot fulfil, the affected amount will be refunded.
Contact us as soon as possible if you notice an error. We will try to help, but changes cannot be guaranteed once diamond sourcing, CAD work, sizing, engraving, personalisation, production or shipping preparation has started. Changes may also affect the quotation and completion date.
04 · PRODUCTS & DIAMONDS
Diamonds described as laboratory-grown or lab-grown are created in a laboratory environment and are not represented by us as mined or natural diamonds.
Where a diamond is supplied with an independent grading report, the issuing laboratory determines the grades and report information.
Photography, video, sketches, CAD and renders help communicate a design. Screen colour, magnification, reflections and scale can differ from the physical piece.
Carat weight, dimensions, metal weight and other measurements may be rounded or subject to ordinary manufacturing tolerances unless expressly stated otherwise.
Fine jewelry is individually manufactured. Minor differences that do not materially change the approved design can occur from piece to piece.
Loose-diamond inventory can change quickly. If a selected diamond becomes unavailable before fulfilment, we may contact you with an alternative or other resolution.
05 · BESPOKE & PERSONALISED JEWELRY
Bespoke, custom-made, engraved, resized, personalised or specially altered jewelry is produced according to the information and approvals you provide.
Check names, dates, spelling, engraving, ring size, diamond selection, metal and other requested details carefully.
Where we send a CAD, sketch, mock-up or design approval, production may proceed after the agreed approval stage.
Small technical adjustments may be required for durability, stone setting, structural integrity or practical manufacture.
Once bespoke or personalised production has begun, changes or change-of-mind cancellation may not be possible.
If you provide photographs, logos, handwriting, artwork, symbols, crests, text or other material, you confirm that you have the right to provide that material and authorise us to use it for your order. You grant Efi & Co permission to reproduce or adapt submitted material only as reasonably needed to quote, design, manufacture, personalise, service or fulfil your order.
06 · RING SIZING
Ring size can vary with band width, design, temperature and measurement method. Please confirm the intended size before ordering, especially where a ring will be made or altered specifically for you.
Some ring designs, including certain eternity, pavé, tension-style or highly detailed settings, may have limited resizing options. Resizing may also affect engraving or the position of stones.
VIEW RING SIZE GUIDE07 · PRICING & PAYMENT
Prices are shown in the currency displayed by your Shopify market or selected store currency. Exchange-rate conversion can cause small differences between displayed estimates and the amount ultimately processed by your payment provider.
We take reasonable care with pricing. If a price is clearly incorrect because of a technical, typographical or system error, we may contact you before fulfilment to explain the issue and offer an appropriate resolution permitted by applicable law.
08 · PRODUCTION & DELIVERY
Many Efi & Co items are made or prepared to order. The production or handling estimate shown on the product page, quotation or order communication is separate from the carrier's transit time.
Production times are estimates. Bespoke designs, diamond sourcing, approvals and complex settings can require additional time.
Delivery dates are estimates unless expressly guaranteed. Carrier, customs, weather, holiday or local delivery disruptions may affect arrival.
Please provide a complete and accurate shipping address. Contact us immediately if you notice a mistake.
When tracking is available, it will normally be provided after dispatch through your shipping confirmation or Shopify order-status page.
09 · TAXES & DUTIES
Depending on your destination and checkout arrangement, local VAT, GST, customs duty, brokerage charges or other import costs may apply.
Unless checkout expressly states that applicable duties or taxes are included, you may be responsible for charges imposed by the destination country, customs authority or carrier. Any calculator or estimate on our website is provided for guidance only; final charges are determined by the relevant authority or service provider.
TAX & DUTIES CALCULATOR10 · RETURNS & CANCELLATION
Return eligibility depends on the item, whether it has been made or altered specifically for you, its condition, and the mandatory consumer rights that apply in your country.
Eligible standard, non-personalised items may be returnable in accordance with our Delivery & Returns policy and applicable law.
Bespoke, engraved, personalised, resized or specially altered pieces may be excluded from change-of-mind returns where applicable law permits.
Nothing in these Terms removes rights that cannot legally be excluded. Where UK or other applicable consumer law gives you cancellation, refund, repair, replacement or other statutory rights, those rights continue to apply.
Change-of-mind restrictions do not remove legal rights relating to goods that are faulty, misdescribed, not as ordered, or otherwise fail to meet mandatory consumer standards. Please contact us promptly with your order number and, where useful, clear photographs.
Contact us before sending an item back. We will confirm eligibility, instructions and the appropriate return address for your order.
READ DELIVERY & RETURNS11 · WARRANTY & AFTERCARE
Efi & Co provides a 1-year warranty for qualifying manufacturing and workmanship issues, subject to the conditions described on our Warranty page. This warranty is in addition to mandatory consumer rights that may apply.
Normal wear, accidental damage, improper care, impacts, loss, theft, unauthorised alteration and other circumstances may fall outside the warranty. If a stone becomes loose or a setting appears damaged, stop wearing the piece and contact us so it can be assessed.
12 · GIFT CARDS
Efi & Co gift cards are digital and are processed through Shopify's gift-card functionality. The recipient receives a unique code that can be entered at checkout.
Where permitted by the gift-card configuration, any eligible unused balance remains on the gift card for a future purchase. Gift cards are not redeemable for cash except where required by law. Any conditions displayed on the gift-card page at the time of purchase also form part of the applicable terms.
13 · PROMOTIONS
Promotions may have separate conditions, including expiry dates, eligible products, minimum spend, customer limits or exclusions. Unless expressly stated otherwise, offers cannot be combined and have no cash value.
We may correct, suspend or withdraw a promotion where reasonably necessary because of an error, misuse, fraud or technical issue, subject to applicable consumer law and orders already validly accepted.
14 · INTELLECTUAL PROPERTY
Unless otherwise stated, the Efi & Co website, branding, text, product photography, illustrations, videos, graphics, jewelry designs, CAD presentations and other content are owned by or licensed to Efi & Co and are protected by applicable intellectual-property laws.
You may use the website for personal shopping and information. You may not reproduce, commercially exploit, distribute, scrape, copy or adapt our content or designs for commercial use without permission, except where the law expressly permits it.
15 · THIRD-PARTY SERVICES
Our store uses third-party services including Shopify, payment providers, couriers and other service providers. Their separate terms or privacy practices may apply when you use their services or follow external links.
We are not responsible for third-party websites or services we do not own or control, except to the extent that applicable law makes us responsible.
16 · LIABILITY
Nothing in these Terms excludes or limits liability where doing so would be unlawful, or removes mandatory rights available to consumers.
To the extent permitted by law, we are not responsible for losses caused by misuse, unauthorised alteration, failure to follow reasonable care instructions, or events outside our reasonable control.
Where you purchase as a consumer, we do not seek to exclude responsibility for losses that applicable consumer law requires us to bear.
17 · EVENTS OUTSIDE OUR CONTROL
Production or delivery can occasionally be affected by circumstances outside our reasonable control, including severe weather, natural disasters, government action, customs disruption, transport interruption, industrial action, major supplier disruption or similar events.
If such an event materially affects your order, we will take reasonable steps to communicate with you and resolve the order in accordance with applicable law.
18 · GOVERNING LAW & DISPUTES
The law governing your purchase may depend on the Efi & Co entity that contracts with you and any mandatory consumer law that applies where you live.
Where ECOPHILIA LTD is the contracting seller, these Terms and the contract are governed by the laws of England and Wales, subject to mandatory consumer protections that apply to you. Where ECOPHILIA COMPANY LIMITED is the contracting seller, these Terms and the contract are governed by the laws of Hong Kong, again subject to mandatory consumer protections that cannot lawfully be excluded.
Nothing in this section prevents a consumer from using any court or dispute-resolution procedure that mandatory law makes available in their jurisdiction.
Please contact us first. We aim to review genuine order, delivery, product or service concerns carefully and work toward an appropriate resolution.
19 · CHANGES TO THESE TERMS
We may update these Terms from time to time to reflect changes to our business, products, services, technology or legal requirements.
The Terms that generally apply to an order are those in effect when the contract for that order was formed, unless a later change must apply by law.
20 · CONTACT
Fine jewelry can involve decisions about diamond specifications, ring size, metal, setting, customisation, delivery and aftercare. If anything is unclear, please ask us before placing your order.
