As a gemologist with over a decade of experience in the field of gemstones, I can provide you with a detailed comparison between rubies and diamonds to address your question.

Rubies and diamonds are both highly valued gemstones, but their worth is determined by a variety of factors, including their rarity, quality, and demand in the market.

Diamonds are known for their exceptional hardness, which is rated as a 10 on the Mohs scale. This makes them the hardest known natural material and gives them a significant edge in terms of durability. The value of a diamond is determined by the 4Cs: carat (weight), cut, color, and clarity. The rarity of a flawless diamond, especially a large one, can make it extremely valuable. Additionally, diamonds have a well-established international market and are widely recognized as a symbol of luxury and status.

Rubies, on the other hand, are corundum gemstones that are prized for their deep red color. The most valuable rubies are referred to as "pigeon's blood" red, which is a vivid and intense shade. The worth of a ruby is influenced by its color, clarity, cut, and carat weight, similar to diamonds. However, rubies are less hard than diamonds, with a rating of 9 on the Mohs scale. This means they are slightly more susceptible to scratches and damage. The rarity of high-quality rubies, especially those from Myanmar (Burma), can also make them very valuable.

In terms of market demand, diamonds tend to have a broader appeal and are more commonly used in engagement rings and other types of jewelry. This widespread use can contribute to their overall value. Rubies, while also sought after, are not as universally popular and may not command the same level of demand.

It's important to note that the value of a gemstone is subjective and can fluctuate based on current market trends and individual preferences. While it's possible for a particularly fine ruby to be worth more than a diamond of similar size and quality, it's not a given. The final value will depend on the specific characteristics of the stones in question and the current market conditions.

In conclusion, while both rubies and diamonds are precious and can command high prices, it's not accurate to say that one is universally worth more than the other without considering the specific details of each stone.
