Valley 1.5 ct Lab Diamond Engagement Ring in 18K Gold

It is a gem formed by the Earth over billions of years, under high pressure and temperature. Each stone carries rarity and a unique history.

It's a lab-grown diamond created in a controlled environment with advanced technology. It has the same composition and physical and chemical properties as a natural diamond.

In terms of durability, they are equivalent.

Both have a hardness of 10 on the Mohs scale, the maximum possible, and behave the same way in daily use, meaning that virtually no other material can scratch them, except another diamond.

However, it is important to understand that the Mohs scale measures scratch resistance, not "indestructibility" or impact resistance (toughness). In other words: natural and lab-grown diamonds are not unbreakable – a strong blow, pressure on edges, or a sudden shock can chip or break the gem.

Therefore, what truly guarantees the stone's security is much more about the well-executed cut, how it is set in the jewelry, and daily care, rather than its natural or lab-grown origin.

These are the criteria used for evaluation: cut, color, clarity, and carat. They determine the brilliance, purity, size, and value of the stone — whether natural or lab-grown.

At Vangolden, we primarily work with natural diamonds of color I, clarity VS+, and excellent cut, and with lab-grown diamonds of color D–E–F, clarity VVS1, and excellent cut, always seeking a balance between beauty, brilliance performance, and value.

However, if you desire another quality range — whether to adjust the budget or follow a specific preference — we can also select diamonds with different characteristics, always transparently explaining the differences in color, clarity, and price to ensure an informed choice.

Yes. Here at Vangolden, we offer recognized gemological certificates for lab-grown diamonds from 1 ct and for natural diamonds from 0.30 ct upon request.

Below these sizes, we work with a strict quality curation, following criteria for cut, color, clarity, and carat, always with transparency about the characteristics of the gem.

If you value tradition, geological rarity, and the history of owning a gem formed by the Earth itself above all else, and don't mind investing more for it, a natural diamond is the most suitable choice.

If you want a real diamond, with the same beauty and durability, but prefer a more rational use of your budget—whether it's to get a larger stone, one with better color and clarity, or to balance it with other plans for the couple—a lab-grown diamond makes a lot of sense.

Ultimately, the ideal decision is one that balances three points: how you feel when you look at the jewelry, what comfortably fits your budget, and what makes the most sense for the story you want to tell with this ring.
