Key Features

In Simple Terms

What it is
"750 on jewelry" is a marking you might see on rings, necklaces, or other pieces. It means the jewelry is made of 75% pure gold, mixed with 25% other metals like silver or copper. Think of it like a smoothie that’s 75% fruit and 25% yogurt—it’s still mostly fruit, but the yogurt makes it stronger.

Why people use it
Pure gold (24k) is too soft for everyday wear—it bends or scratches easily. By mixing it with other metals (making it "750"), the jewelry becomes more durable while still looking like gold. It’s a balance between luxury and practicality.

Basic examples
  • A wedding ring marked "750" won’t lose its shape as quickly as pure gold but still has that rich gold color.
  • A necklace with this marking is less likely to break if accidentally tugged, thanks to the stronger metals mixed in.
  • It’s more affordable than pure gold but still valuable, like buying a high-quality item that lasts instead of the most expensive (but fragile) option.
  • Technical Details

    What it is


    The term "750 on jewelry" refers to a purity mark indicating that the piece is made of 75% pure gold, commonly known as 18-karat gold. It falls under the category of gold hallmarks, which are stamps or engravings used to certify the metal's quality and composition. The "750" denotes that the jewelry contains 750 parts gold per 1,000 parts of the alloy, with the remaining 250 parts consisting of other metals like silver, copper, or palladium.

    How it works


    The "750" hallmark is typically stamped or laser-engraved onto the jewelry during manufacturing. This process involves precise machinery or hand tools to ensure the mark is legible and permanent. The hallmark serves as a verification mechanism for buyers and sellers, confirming the gold's purity. Regulatory bodies or independent assay offices often oversee the marking process to prevent fraud.

    Key components


    The primary components of "750" jewelry include:
  • Gold: The dominant metal, making up 75% of the alloy.
  • Alloy metals: Such as copper (for durability and warmth), silver (for brightness), or palladium (for whiteness in white gold).
  • Hallmark stamp: The "750" engraving, often accompanied by other marks like the manufacturer's logo or country of origin.

  • Common use cases


    "750" gold is widely used in high-quality jewelry due to its balance of purity and durability. Common applications include:
  • Engagement rings and wedding bands: Preferred for their luxury and longevity.
  • Necklaces, bracelets, and earrings: Often chosen for everyday wear or special occasions.
  • Luxury watches: Used in watch cases or bezels for a premium finish.
  • Custom or designer jewelry: Favored by artisans for its workability and aesthetic appeal.
