popular questions

Natural rubies are highly popular and valuable gemstones, prized for their beautiful color and rarity in the jewelry world. Here are some common questions and answers about natural rubies:

A natural ruby is a precious gemstone made from the mineral corundum, composed of aluminum, oxygen, chromium, and other elements. Its red color comes from the presence of chromium. Ruby is one of the hardest gemstones, ranking 9 on the Mohs scale, just below diamond. Natural rubies are usually cut and polished for use in jewelry, such as rings and necklaces.

There are many synthetic rubies on the market today. The main differences between natural and synthetic rubies are:

  • Inclusions: Natural rubies often contain tiny inclusions (such as gas bubbles or mineral particles), known as “natural marks.” Synthetic rubies typically lack these natural inclusions or have different types of inclusions.
  • Color: Natural rubies generally have a more natural color variation, while synthetic rubies may appear too uniform.
  • Hardness: Rubies have a hardness of 9. If you scratch it with a tool, the natural ruby will show clear signs of its hardness.

The price of a ruby is mainly influenced by the following factors:

  • Color: Color is the most important factor in determining a ruby’s price. Deep and vibrant “pigeon blood red” rubies are the most valuable.
  • Size: Larger rubies (measured in carats) are rarer and more expensive.
  • Clarity: Rubies with high transparency and fewer inclusions are more valuable. Natural rubies typically have some inclusions, but those with better clarity are more expensive.
  • Origin: Rubies from certain regions (like Myanmar) are considered higher quality and are priced accordingly.

Although rubies are very hard, they still require careful maintenance:

  • Avoid impacts: Despite their hardness, rubies can still break or chip from strong impacts or significant temperature changes.
  • Cleaning: Clean rubies with warm water and mild soap using a soft cloth. Avoid using harsh chemicals.
  • Avoid high temperatures and chemicals: Keep rubies away from high heat or strong chemicals to preserve their color and structure.

Major sources of rubies include:

  • Myanmar: Rubies from Myanmar are famous for their high-quality “pigeon blood red” color and are one of the most well-known ruby sources.
  • Thailand: Rubies from Thailand are typically darker and more common.
  • Sri Lanka: Sri Lanka also produces high-quality rubies, especially lighter-colored ones.
  • Tanzania, Mozambique, etc.: These regions have become important sources of rubies in recent years.
