All orders require a minimum of 2 weeks for production. Please note that requests involving more complex designs, certified stones, or fancy cut stones are unlikely to be expedited, as these require time to source and select.

We understand that lab grown diamond pricing can vary widely; you may come across lower prices, or sometimes much higher. At tinxx, we take a fair and consistent approach. Our pricing reflects the quality of our materials, the care and expertise behind each piece, and the standard we maintain across everything from our jewelry to our packaging and customer support.

We use solid 14K or 18K gold, never plated or vermeil. We source our materials ourselves and hand-select diamonds for their cut, clarity, color, and overall quality. Each piece is made to order with care and backed by decades of experience in diamond trading and jewelry manufacturing.

As a small business, kindly understand that we're not able to offer returns or exchanges, including for sizing. Please double-check your measurements before placing your order, and feel free to reach out if you need help. We’re always happy to assist.

Due to the high variance in gold and diamond usage across sizes, we list a limited selection on our website. However, if you’re interested in a different size, please contact us for a tailored quotation.

tinxx operates primarily online, and many of our clients purchase both website designs and custom pieces entirely through our website, email, and WhatsApp. We regularly guide clients through the process with detailed photos, videos, stone options, measurements, and design updates, so you can make an informed decision without needing to see the piece in person.

For clients in Hong Kong, a small selection of pieces may be available to view by appointment, subject to availability. Please contact us by email or WhatsApp if you would like to inquire.

Our base prices are set in Hong Kong dollars. Depending on your location, prices may also be displayed in your local currency.

You can change the displayed currency using the currency selector on our website. The currency and final amount charged will be shown at checkout before payment.

Most tinxx pieces are made to order and take approximately 3 to 8 weeks to complete, depending on the design. Pieces requiring specific certified stones, fancy cuts, or custom details may take toward the longer end, as additional time can be required for sourcing and production.

At tinxx, quality is our top priority. Every piece is carefully inspected before shipment, and we stand by the craftsmanship of our jewelry. Your jewelry is protected by a 1-year warranty that covers manufacturing defects.

This warranty does not apply to:

• Loss of luster, dirt build-up, or scratches
  
• Accidental damage, impact, or mishandling
  
• Alterations, resizing, or repairs performed by a third party
  
• Theft or loss

If you believe your piece has a manufacturing defect:

1. Contact our Customer Service team by email with detailed images and a description of the issue.
   
2. Our team will review your request and may ask you to return the piece for inspection.
   
3. If a manufacturing defect is confirmed, we will repair your jewelry at no cost.

Repairs outside of the 1-year warranty are available for a service fee. Our team will provide a quote before proceeding.

Please note that customers are responsible for the cost to ship to our Hong Kong studio location.

Absolutely! We understand that you may have specific requirements or would like to personalize an existing design, and we'd love to help. Fill out this form and we will get back to you as soon as possible.

Adapting Existing Designs

If you’d like to adjust one of our designs, please provide link to the piece along with your specifications. The more detail you can provide, the better. We’ll review feasibility and confirm the next steps with you.

Fully Bespoke Creations

For fully bespoke designs, we’ll carefully evaluate your request and provide an estimated quote and timeline. To help us bring your vision to life, please share reference images, sizes, and any details you’d like incorporated.

By placing a bespoke order, you agree that we may photograph and feature the design on our website and brand channels.

Yes, we offer engraving on most of our products. If engraving is available, you will have the option to enter your personalization on the product page, subject to the stated character limits.

The character limits shown on each product are what have worked best in the past for legibility and finish. If you’re keen to go longer, please contact us and we’ll check what’s possible for your specific piece. Some designs are simply too small to accommodate more characters. Share what you have in mind, and we’ll advise on feasibility and alternatives.

We use a clean, standard sans serif font for all engravings. At this time, we are not able to offer font customization, but if you have a specific request, please reach out and we’ll do our best to see what’s possible.

If you need to make any changes to the engraving on your order, please contact us within 48 hours of your purchase.

Unfortunately, we are unable to make changes to the engraving after your order has arrived. As each piece is custom-made to order, we recommend double-checking the engraving details before confirming your purchase.

Lab grown diamonds

Lab grown diamonds of 1.00ct and above are accompanied by an IGI grading report and selected to a minimum standard of F color and VS1 clarity. This is the minimum quality standard we use for larger lab-grown diamonds and one we have found to perform beautifully in fine jewelry.

Beyond this baseline, we place greater emphasis on the individual stone, particularly its cut, proportions, and overall appearance. This allows us to focus on finding the best stone for each piece rather than selecting based on color and clarity grades alone.

Smaller lab-grown diamonds are not individually certified, as the cost of grading can be disproportionate to the value of the stone and does not materially change how we assess its quality.

If you have specific preferences for color, clarity, cut, or other grading characteristics, we are happy to source accordingly. You can also request to review the grading report and available stone options before your diamond is set, so we can select the stone together.

Natural diamonds

The natural diamond options priced directly on our website generally feature smaller stones and are not individually certified. Accent and pavé diamonds are also not individually certified, as is standard in fine jewelry, and are instead selected to meet our color, clarity, cut, and overall quality standards.

Natural diamonds above 0.50ct are accompanied by a GIA grading report.

For designs involving larger natural diamonds, generally from around 0.30ct and above, pricing may not be listed directly on the website. Natural diamond prices can vary considerably depending on the individual stone's carat weight, color, clarity, cut, proportions, and grading report, so these stones are quoted individually. This also allows us to source options based on your preferred specifications and budget.

Our diamonds are sourced through long-standing, trusted suppliers we have worked with over decades in the industry. All diamonds are conflict-free and comply with the Kimberley Process based on supplier guarantees.

We offer solid gold in 14K and 18K. 18K gold is composed of 75% pure gold, which gives it its warm, saturated color and luxurious feel. 14K gold contains 58.3% pure gold, with a higher proportion of alloy metals that add extra strength and resilience for everyday wear. Both are solid, fine gold. Choose the one that suits the way you live and wear your jewelry.

We offer our designs in solid white, yellow, and rose gold, so you can choose the finish that best suits your skin tone and personal style. Whether you lean toward the cool elegance of white gold, the warmth of yellow gold, or the soft, romantic tone of rose gold, each piece is crafted from solid gold for rich color, lasting durability, and a luxurious feel.

Yes. Because the gold content is exactly the same in all three colors, the pricing does not vary. The difference is purely in color and personal preference, not in value.
