Size Guide
Measure the circumference of your finger and use the table below to determine your size. Remember to measure at the end of the day and make sure your hands aren’t too hot or cold. Band rings should fit snugly at the base of the finger, but wide enough to fit over the widest part of the finger. Wider rings should be worn looser. If your ideal fit falls between two sizes, we recommend choosing the larger size.

Honest Pricing
Our pricing is simple and transparent: daily metal price + 7879 fee — so you know exactly what you’re paying for. We believe in fair pricing and pure metals — no inflated markups, no compromises. Unlike many brands that charge up to 1000% for diluted metals, we apply a modest artisan fee for our 24K gold and pure platinum pieces. This covers everything from in-house design and expert craftsmanship to hand-finishing, quality control, shipping, hallmarking, and premium packaging. Luxury, without the unnecessary markup.
Superior Purity
The true value of jewellery comes down to purity. Gold is measured in karats — 24K (99.9% pure) is the highest, followed by 18K (75% pure), 14K (58.3% pure), and 10K (41.7% pure). Platinum is graded in parts per thousand, with 9999 being the purest at 99.99%. We specialise in 24K gold and pure platinum, ensuring every piece is as valuable as it is beautiful.
Priced By Weight
Our 24K gold and 99.9% platinum are as pure as it gets — the same quality as investment-grade bullion. That’s why we sell our pieces by weight, with prices updated in real-time based on the stock market. When you buy from us, you’re not just getting jewellery — you’re investing in a real, tradeable asset that typically holds its value. And if you ever decide to sell, you can sell it back to us anytime.
Your Jewellery Investment Portfolio
As gold and platinum prices rise, so does the value of your jewellery. With your personalised 7879 portfolio, you can track your jewellery's real-time value anytime. And if you ever choose to sell, you can trade your jewellery back to us at the current market price minus just 4% — one of the best rates available. Flexible, fair, and transparent.
