Let’s go through the details one by one.

1. Red Diamond

Diamonds are a rare type of gemstone and also one of the most expensive. Red diamond is the rarest type of diamonds and hence it is the most valuable as well.

Diamonds are the hardest material on earth with a hardness of 10 in the Moh’s scale and therefore it is the ultimate scratch resistant material. But diamonds are not as tough as sapphire and it can chip or crack if faced with a hard knock.

There are different tones of red diamonds available and as per GIA classification, the highest ratings goes for the “fancy vivid” color diamonds.

Synthetic red diamonds are also available in the market and hence, buying from a highly trusted source such as Leibish is recommended.

(Refractive index is a measurement of the brilliance/luster of a gemstone)

Extremely rare and hence it will be a highly unique possession.

Diamonds are the most durable gemstone and also the gemstone with the highest luster.

Very high prices

2. Ruby

Ruby belongs to the corundum mineral family and it is the red variation of sapphire. “Ruby” is the trade name used for red corundum and the term “Red Sapphire” is not used in the industry. It is also one of the most popular gemstones in the world.

Heat treatment to enhance the color is very common for rubies. Heat treatment is an accepted treatment type in the industry and it should not be a problem as long as it is disclosed. Natural untreated rubies are rare and more expensive. If a seller is claiming a ruby to be natural, you should always request for the gemstone certificate mentioning the treatment type.

Ruby has a hardness of 9 in the Moh’s scale of hardness which is second only to diamond. Due to its compact structure and absence of cleavage, rubies are more resistant to cracking and chipping than diamond.

3. Red Spinel

Spinel is another very popular and a beautiful gemstone, and red and blue spinels are the most expensive. There are quite few different shades of red spinel. “Pigeon Blood” red spinels were misidentified as rubies throughout the history until the two were differentiated in the 19th
century. Therefore, it is a great alternative for ruby. Another fascinating variation of red spinels is “Jedi” spinel which has a bright neon red color.

Spinel has a hardness of 8 in the Moh’s scale of hardness and a refractive index of 1.71. Therefore, this stone is a very durable gemstone with good brilliance and it is a great choice for everyday jewelry.

Although not as common as synthetic sapphires, lab grown spinels are available. The GRS (Gem Research Swiss Lab) issued a notice about lab grown spinels in 2015.

Therefore, when you are purchasing expensive spinel gemstones or jewelry, you should buy from a trustworthy seller or request for a gemstone certificate.

(Note : Although red is the most popular color for garnet, there are several other colors such as green orange, yellow and pink)

As a stone found in abundance, eye clean and transparent stones are easy to find. Garnets are also mostly untreated. There are several variations of garnet and depending on the type, its hardness can vary from 6.5 to 7.5. Therefore, garnet is not as durable as the gemstones we spoke about so far.

Rubellite is the name given for pinkish red tourmaline. The color range from pinkish red to purplish red and the prices increase when the color is more towards pinkish red.

With a hardness of 7 – 7.5, it has a reasonably good durability and is also an affordable gemstone. Heat treatments are common for tourmaline and buying treated stones should not be that much of a concern. If the seller is claiming that the stone is free of treatments, it is better to ask for a gemstone certificate to prove that claim.

Due to the crystal structure of tourmaline, most stones are cut in long shapes.
