eBay Customer Reviews

Is Antique and Vintage Jewellery a Good Investment?

Yes, Antique Jewellery is more likely to retain or increase its value over the years, making it a better choice if you are looking for a good investment. As time goes by, Antique Jewellery becomes even rarer at it ages, and this makes they highly desirable among those who appreciate the beauty of bygone eras. Gold has consistently risen in value and more than doubled in the last ten years alone. The Historic price increase gives confidence that your Antique or Vintage jewellery is not only of fantastic Value but may prove to be one of the wisest investments you could make.

Why is Pre-Loved, Vintage and Antique Jewellery Excellent Value? 

Pre-love, Vintage and Antique Jewellery is VAT exempt so you will at least pay 20% less than you would for an equivalent piece made today. When purchased from an online it is further discounted than when sold in a high street store as there is less overhead costs to account for.

Why Does Antique Jewellery Retain Its Value?

Antique jewellery retains its value, unlike new jewellery which loses value as soon as it has been purchased, antique jewellery has already transitioned from 'new' to 'old' before purchase, ensuring its worth remains steadfast.

Why Does Antique Jewellery Appreciate?

The superb craftsmanship, uniqueness, and unmatched quality of a past time makes antique jewellery highly desirable and collectible. As time passes, fewer antique items remain available, enhancing their value much like classic cars that are always in demand and retain their worth. Each piece in our collection is unique and forever cherished, reflecting the rich history and artistry that makes it so special.

Why Is Antique Jewellery Better Quality Than Modern Jewellery?  

Each unique piece tells a story and has passed the test of time by making it intact to the present day, showcasing its exceptional quality. With proper care, these exquisitely crafted rings will remain robust and cherished for generations to come. Today, most modern jewellery is cast and replicated 100’s of times, whereas antique and vintage jewellery were almost always hand-made or, in the case of newer vintage pieces, hand-finished. Even in high-end bespoke modern pieces, capturing the same level of quality and workmanship as seen in antique and vintage jewellery is almost impossible. Antique Jewellery is set with highly desirable natural diamonds which are eco-friendly and conflict free, modern day jewellery tends to be set with lab created diamonds

Why is Antique Jewellery Unique?

Antique jewellery was not mass-produced or widely available as it is today, making it highly unlikely that you will ever find a duplicate of a piece of antique jewellery. These treasures were often created as one-of-a-kind masterpieces by highly skilled 3rd, 4th and 5th generation talented jewellery for members of the upper classes.
