Metal Education

At DiamondGarden, we offer a fine selection of metals to enhance the beauty of our lab-grown, conflict-free diamonds.


Gold, although more malleable than any other metal, is immune to rust or erosion. It also will not tarnish or corrode.

Gold’s purity is demonstrated through Karatage, (K). A number before the letter K is a representation of how much gold makes up the jewelry. The highest level of purity is not acceptable for jewelry, as it is too malleable. The strength is reinforced through the use of other metals, giving it a more lasting durability.

Colored gold is created based upon the metal alloys that are included in the jewelry and their percentage.

Yellow Gold
The purity of 18k yellow gold gives it an exquisitely pure color that shines bright alongside our diamonds. This is the color that gold is known for.

Because the element Au, or Gold, was one of the earliest known metals, it defines the entire world’s currency system.

Carat Percentage Description
24 100% So soft that it can’t be used for jewelry
22 91.7% Very soft, not ideal for diamond jewelry but great for plain gold jewellery without any gemstones
18 75.0% Recommended for only the finest diamond jewelry
14 58.3% Suitable for jewelry
12 50.0% Not adequate for jewelry
10 41.7% Not adequate for jewelry

White Gold

White Gold offers the wearer a brilliant shine, with a shimmering silver that is created through the mixture of 14k gold and rhodium’s naturally shiny white surface. While the rhodium plate may eventually wear down with time, it can easily be re-plated.

Rose Gold

Rose gold uses copper in the metal alloy, giving it a subtle blush of color that is elegant in tone.


The pricing of our gold jewelry depends on the prices of gold quoted worldwide. In addition to this, the diamond jewellery pricing is based on the lab-made, conflict free diamond with which it is paired and on the purity of the gold that you choose.


In order to maintain your gold’s optimal state, it is important to take your ring off when dealing with harsh, potentially corrosive chemicals. If you would like to clean your jewellery, you can mix warm water and detergent free soap, scrubbing your ring with a soft-bristled brunch and a gentle touch.


Like gold, pure silver is too soft and malleable to be used for jewelry. Sterling silver is the more durable product, mixing fine silver with other metals to make it stronger. Sterling silver shimmers bright, not unlike the moon in the night sky. It’s the most affordable of the precious metals, but that does not mean it's lacking in appearance. Silver jewelry has been considered valuable for centuries, creating a captivating and subtly stunning look.


Platinum boosts the beauty of the diamond due to its silvery gleam. Platinum is stronger than gold, and this durability may be one of its most prominent characteristics. Platinum refuses to wear down, making it a symbol of longevity. While other metals often need to be reinforced, platinum does not. Although platinum is one of the strongest metals, it can develop a patina. This can be, if the wearer wants, polished back to its original luster.

Recycled Metals Program

All metals used in DiamondGarden’s jewellery is primarily made with recycled and re-refined precious metals. Because our recycled and re-refined silver, gold, platinum, and palladium are refined back into their pure elements, they are of the same high quality as newly mined metals, without the level of degradation to our natural resources caused by new mining.

We continually work towards increasing the recycled content and improving reporting regarding our products. We were one of the first jewellers to elect to have an independent audit of our supply chain to provide additional verification that the metals we use meet the standards for recycled content. We work with third party verification systems to verify the amount of recycled content of our precious metals and continually improve our suppliers’ systems for managing and sourcing these materials according to our best practices.

DiamondGarden’s precious metals come from numerous sources, including post-consumer materials, such as existing jewelry, industrial-use metals, and electronics components; material from in-house recycling, refining, and product manufacturing or other secondary sources; and investment gold and gold-bearing products.
