At Alter's Gem Jewelry, we offer a wide range of gold jewelry crafted from different gold types, including various karats and colors, to cater to individual preferences and styles.

Gold Karat Options

Gold is measured in karats, indicating its purity. The most common karat options include:
  • 24K Gold: Considered the purest form of gold, 24K gold boasts a purity of 99.9% and exhibits a rich, yellow color. People highly value it for its inherent beauty and rarity. While 24-karat gold exudes luxury, it is seldom used in jewelry making due to its excessive softness. Gold in its purest form, such as 24K gold lacks the necessary durability to withstand everyday wear and tear.
  • 22K Gold: Due to its composition of 91.7% pure gold mixed with other metals, 22K gold is a preferred choice among jewelers for creating jewelry. This alloy provides a balance between durability and purity, making it suitable for various jewelry pieces. Its distinctive yellow hue adds a touch of elegance and charm. In Indian jewelry making, 22-karat gold holds a significant role due to its unique attributes and cultural importance. The high gold content makes it highly valuable, while the addition of other metals enhances its strength and resilience. This makes it ideal for crafting intricate designs and delicate patterns that are characteristic of Indian jewelry.
  • 18K Gold: A popular choice for fine jewelry, 18K gold comprises 75% pure gold blended with other metals to enhance its strength. It strikes a desirable balance between purity and durability, providing a luxurious and enduring option. 18k is a popular choice for luxury brands and bridal jewelry as there are enough alloys to make it durable enough, yet very luxurious.
  • 14K Gold: With a composition of 58.3% pure gold, 14K gold presents a durable and affordable choice for jewelry. It offers excellent strength and finds widespread use in various jewelry designs.
  • 10K Gold: Recognized as the most durable and budget-friendly option, 10K gold contains 41.7% pure gold. It exhibits remarkable resistance to scratches and wear, making it an ideal choice for everyday jewelry.

Gold Color Options

Gold is available in different colors, achieved through the use of various alloys. The most popular gold colors include:

  • Yellow Gold: The classic and timeless choice, yellow gold showcases the natural beauty and warmth of gold. It exudes a traditional and elegant appeal that suits a wide range of styles.

  • Rose Gold: Achieved by mixing gold with copper alloys, rose gold captivates with its romantic and blush-toned hue. It adds a touch of modernity and elegance to any jewelry piece

Gold Quality Markings

Gold quality markings serve to indicate the purity and composition of gold in jewelry. These markings provide important information to consumers, helping them understand the value and quality of the gold used. Here are the common gold quality markings:
