Nothing we know lasts longer. Nothing bends light so clearly. A diamond doesn't forget what it once was, it carries it forward, one year after another.
Why, explained →The years change. The diamond stays. That's exactly why one belongs in every pearl.
A diamond is pure carbon grown into a crystal: in the earth under enormous pressure and heat over billions of years, in a laboratory within a few weeks. Diamond is the hardest natural material. That's why every Bondingoo pearl carries a certified laboratory-grown diamond from the start. Not because it makes the piece more valuable. But because the year the pearl stands for already is.
At first glance they all shine. You only see the difference after years on your wrist.
| Stone | Material | Hardness | Sparkle | After 20 years | Price | A diamond? |
|---|---|---|---|---|---|---|
Natural diamond Formed in the earth. Rare and beautiful, but many times more expensive. | pure carbon | 10 of 10 | white and clear | like new | €€€€€ | Yes |
Laboratory-grown diamond Grown in a laboratory and certified. Even experts can only tell it apart from a natural diamond with laboratory equipment. In every Bondingoo pearl | pure carbon | 10 of 10 | white and clear | like new | €€€€€ | Yes |
Moissanite Very hard and brilliant, but with a much more colourful sparkle than a diamond. Beautiful, but not a diamond. | silicon carbide | 9.25 of 10 | rainbow-coloured | almost like new | €€€€€ | No |
Cubic zirconia An imitation that convinces on day one. Over the years it scratches and turns dull. | zirconium dioxide | 8 of 10 | similar at first | visibly worn | €€€€€ | No |
Hardness on the Mohs scale. It decides whether a stone still looks like it did on day one after years of everyday wear.
That's why Bondingoo chooses the laboratory-grown diamond: a diamond that stays, and affordable enough for every pearl to carry one of 1 carat or more, year after year.
Every pearl carries a laboratory-grown diamond from 1 carat, at no extra cost. An independent gemmological laboratory certifies cut, clarity, colour and carat, and the certificate goes into your Bondingoo History. How large your diamond is, you decide. The pearl follows it, so that the diamond sits flush and the pearl can be drilled through its centre:
Pearls and diamonds shown to scale.
Bondingoo is an investment of a special kind. What you invest is years. What grows is memories. What remains is a legacy.
A year in which you consciously look at each other. You will look back on it with pride.
Every pearl holds one year. Your band shows how often you have chosen each other.
Every year is recorded in your Bondingoo History, exportable as a PDF at any time.
Every year one more diamond in your family history. What a treasure.
One day your children, grandchildren and great-grandchildren, or whoever comes after you, will hold your band in their hands and read your story. A role model, an estate, an inheritance of priceless value. Everyone can be proud of it.
