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 approach. Our pricing reflects not just the materials, but the care, expertise, and thought that go into every piece.

We use 18K solid gold, not vermeil, and not 14K or 10K. With its higher gold content, 18K offers a richer finish and also comes at a higher cost than the lower karat weights commonly used in commercial fine jewelry. We source all raw materials ourselves, hand-selecting stones for their cut, clarity, color, and overall quality. Each piece is made to order with care and supported by decades of trusted industry experience.

From our jewelry to our packaging to our customer support, every detail matters. We apply a fair, consistent markup that allows us to maintain uncompromising quality, with every piece reflecting the time, skill, and care involved.

We also provide complimentary shipping worldwide. International orders are shipped via DHL Express from Hong Kong with insurance. As shipping is costly, our pricing outside Hong Kong may be slightly higher.

As a small business, kindly understand that we’re not yet able to offer free returns or exchanges 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.

Shipping is included on all orders. We ship worldwide with DHL Express. Delivery takes 2-3 business days after your order leaves our studio, though customs or remote locations may add extra time. A tracking link will be sent to your email once your order is dispatched.

This warranty does not apply to:

• Normal wear and tear
  
• 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.

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. If the piece is intended as a gift or proposal, we can wait to post until after your special moment.

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.

We offer our designs in 18K 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 18K gold for rich color, lasting durability, and a luxurious feel.

Yes. all tinxx pieces are crafted from 18K solid gold, which means they contain 75% pure gold, regardless of the color. The remaining 25% is made up of alloy metals that give each gold its unique tone:

• Yellow gold blends pure gold with silver and a small amount of copper, keeping a warm, natural gold hue.
• White gold mixes gold with palladium or nickel, then is typically rhodium-plated for a bright white finish.
• Rose gold combines gold with a higher percentage of copper, giving it a soft pink tone.

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

At tinxx, we craft all our jewelry in 18K gold because it offers the perfect balance of beauty, durability, comfort, and timeless luxury. Here’s how it compares to other metals:

18K Gold vs. Platinum

• Color & Radiance: 18K gold has a warm, luminous glow—whether in yellow, white, or rose—that reflects light beautifully and flatters the skin. Platinum has a cooler, grayish-white tone and a softer, more muted shine.
• Weight: Platinum is denser and heavier, which can feel bulky for everyday wear. 18K gold is lighter and more comfortable to wear across rings, earrings, and bracelets.
• Finish Over Time: Platinum is highly durable but scratches visibly and develops a patina—a matte finish that dulls its initial shine. 18K gold can easily be polished back to brilliance, keeping its luxurious glow for years.
• Feel: Platinum is often perceived as exclusive due to its rarity, but 18K gold offers a more vibrant look with greater comfort—and is the gold standard for fine jewelry worldwide.

18K Gold vs. 24K Gold

• Purity: 24K is pure gold (100%) and naturally radiant—but also very soft and prone to bending, scratching, and wearing down. It’s rarely used in fine jewelry that’s meant to last.
• Durability: 18K gold blends 75% pure gold with 25% strengthening metals to create a piece that is both beautiful and wearable.
• Practicality: 18K gold offers the richness of high-purity gold with the strength needed for everyday wear, making it the ideal balance of elegance and functionality.

18K Gold vs. Lower-Karat Gold (14K, 10K)

• Color & Shine: The higher gold content in 18K creates a deeper, more radiant tone than 14K or 10K, which can appear more muted or brassy.
• Luxury Feel: 18K gold has a smoother, more refined feel—what you see and touch is closer to pure gold.
• Skin Sensitivity: Lower-karat gold contains a higher percentage of alloy metals, which can sometimes irritate sensitive skin. 18K gold is gentler and more hypoallergenic.
• Prestige: 14K and 10K are commonly used in mass-market jewelry. 18K is the standard for luxury pieces crafted to celebrate life’s most meaningful moments.
