When choosing jewelry, design and diamond quality are certainly important, but "material" is actually a very crucial point.
At BANYAN, all our jewelry is made with K10 (10k gold), K18 (18k gold), and Platinum (Pt). And did you know that each of these materials has different charms and characteristics?
This time, to help you enjoy BANYAN jewelry even more, we will introduce the characteristics of each material and tips on how to choose them.
Things to know: K10, K18, Platinum - Their respective characteristics
1. K10 Yellow Gold (10k gold)
- Characteristics: The purity of gold is 10K, meaning it contains about 42% gold. The remaining approximately 58% consists of other metals (alloys) such as silver and copper, added to adjust strength and color.
-
Charm:
- Soft and gentle hue: It features a subtle yet elegant gold shimmer that blends well with the skin.
- Affordable price: Due to its lower gold purity compared to K18, gold jewelry can be enjoyed at a relatively more reasonable price.
- Ideal for everyday use: The higher proportion of alloys means it has greater hardness than K18, making it more resistant to scratches. Even BANYAN's delicate designs offer sufficient durability for daily wear.
-
Recommended for:
- Those who want to try gold jewelry for the first time.
- Those who want to enjoy the sparkle of gold casually for everyday wear.
- Those who prefer a gentle hue that blends well with the skin.
2. K10 White Gold (10k white gold)
- Characteristics: This alloy is made by mixing gold with white metals such as silver or palladium. It is generally rhodium-plated on the surface, giving it a white sheen similar to platinum. The gold content is approximately 42%.
-
Charm:
- Cool and modern brilliance: Its unique cool, white luster, different from silver or platinum, is appealing. It also has the effect of enhancing the sparkle of diamonds.
- Versatility with various designs: Its high versatility allows it to be paired with any type of jewelry, from modern to delicate designs.
- More affordable than K18 white gold or platinum: You can enjoy white sparkling jewelry at a relatively reasonable price.

Solitaire Diamond Necklace 1ct
- Characteristics: The purity of gold is 18K, meaning it contains approximately 75% gold. The remaining approximately 25% is alloy.

Charm:
- Deep and rich luster: Due to its higher gold purity, it has a deeper and purer gold luster than K10. It is the most popular jewelry material and has a luxurious feel.

Charm:
- Pure white brilliance: It features the unique, unadulterated pure white brilliance of platinum. It pairs exceptionally well with white sparkling diamonds, maximizing their sparkle.
- High durability: It possesses superior durability, being more resistant to scratches and deformation than gold. Therefore, it is often chosen for "long-lasting" jewelry such as engagement rings and wedding bands.
- Hypoallergenic: It has properties that are less likely to cause allergic reactions, making it a relatively safe choice for those concerned about metal allergies.
- Rarity: Its scarcity on Earth makes it a valuable precious metal.

Tips for finding the perfect material for you
Considering the characteristics of each material, choose according to your lifestyle and the image of the jewelry you desire.
-
Choose by lifestyle:
- Mainly for everyday use, and want to enjoy it casually: K10 blends well into daily life, is durable, and attractively priced.
- Concerned about scratches: K10 and platinum have high hardness and tend to be scratch-resistant.
- Prioritizing luxury and value: K18 and platinum have value suitable for a lifetime piece.
-
Choose by preferred color tone:
- Gentle gold that blends with the skin: The subtle hue of K10 yellow gold is recommended.
- Gold with a rich presence: The deep luster of K18 yellow gold is captivating.
- Cool and modern white luster: K10 white gold or platinum is perfect. Platinum has a purer white color.
-
Choose based on allergies:
- If you are concerned about metal allergies, platinum, with its high purity and low likelihood of causing allergic reactions, is most recommended. K18 is also considered relatively hypoallergenic. Although K10 white gold is an alloy, BANYAN chooses materials with minimal allergy concerns.
-
Choose by budget:
- Generally, the price increases in the order of K10 < K18 < Platinum. Choose the optimal material according to your budget.
