GOLD JEWELLERY

Gold is the most iconic jewellery metal, valued for its natural beauty, rarity, and history in trade and culture for thousands of years. It is resistant to rust, tarnish, and corrosion, but is naturally soft—so it is always mixed with other metals for strength.

Gold Properties

  • Very malleable (can be shaped easily)
  • Resistant to tarnish and corrosion
  • Highly valuable and globally traded
  • Soft in pure form, so it is alloyed for jewellery use

Gold Purity (Carats/Karats)

  • 24kt – 100% pure gold (too soft for jewellery)
  • 18kt – 75% gold (luxury standard, durable)
  • 14kt – 58.5% gold (stronger, more durable)
  • 9kt – 37.5% gold (most affordable solid gold option)

Gold Colours

  • Yellow Gold – The most traditional gold colour, reflecting gold in its natural form.
  • White Gold – White gold is made by blending yellow gold with white metals and finishing it with rhodium plating.
  • Rose Gold – Rose gold gets its pink tone from copper in the alloy.

9KT BONDED GOLD

Bevilles’ Bonded Gold jewellery is 9kt gold bonded to Sterling silver. It is made by using heat and pressure to permanently fuse a thick layer of 9 karat gold (10% of total metal weight) onto a base metal core of 925 Sterling Silver.

Bonded gold is one of the most durable and long-lasting alternatives to solid gold jewelry available today. Crafted by permanently fusing a thick layer of real gold to a sterling silver core under intense heat and pressure, it's designed to resist tarnishing and fading through years of everyday wear. The result is the luxurious look and feel of fine gold, with the durability and skin-friendly comfort to wear it every day.

  • As durable as 9kt gold
  • Stronger and longer-lasting than standard plating
  • Affordable way to wear larger statement pieces

SILVER JEWELLERY

Silver is a precious metal that has been valued for thousands of years in trade, art, and culture. It is soft and malleable like gold, so it is usually strengthened with alloys.

  • Bright, reflective shine
  • More abundant and affordable than gold
  • Can tarnish or oxidise over time
  • Requires occasional cleaning and polishing

Silver also has historical and modern importance, from early currency systems to use in technology, medicine, and water purification.

Sterling Silver

The most common silver used in jewellery. “925” = sterling silver quality stamp = 92.5% real silver.

  • 92.5% silver + 7.5% other metals (usually copper)
  • Stronger and more durable than pure silver
  • Affordable and widely available
  • Resistant to everyday wear with proper care
