and how it revolutionizes the value of precious metals.
No Retail Markup
We apply a modest, transparent craftsmanship fee, avoiding the high markups of up to 10x seen elsewhere on diluted precious metals. Our fee covers in-house design, artisan craftsmanship, hand- finishing, quality control, shipping, duties, hallmarking, storage, logistics, premium packaging, and postage. Our retail pricing formula is: daily metal price + 7879 fee + 20% VAT
Superior Purity
The real value of jewellery depends on the purity of its materials. Gold purity 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 purity is quantified in parts per thousand (9999 = 99.99%). Be aware that any gold below 24K includes other alloys, reducing its value. We exclusively offer 24K gold and pure platinum.
Priced by Weight
Our products are crafted from the highest quality materials: pure platinum and 24K gold. We prioritize giving our customers excellent value by not charging extra for brand name. Our pricing is straightforward, based on the weight of the metal plus a modest fee.
Track your jewellery value and sell back at anytime
As platinum and gold prices increase, the value of your jewellery appreciates accordingly. Use your personalized 7879 portfolio to monitor the real-time value of your assets. You have the flexibility to sell your jewellery back to us at any time, receiving the current market price minus 4% - one of the best rates on the market.
