Hence avoid wearing diamonds with yellow sapphires and emerald stones. Do not wear pearls, corals, and rubies with blue sapphires. These are Saturnian stones that cannot be combined with the stones of the sun and moon and Mars. Do not wear pearl and rubies together i.e. do not combine the energies of the moon and sun.
Some people wear different gemstones together. But exercise caution. Ruby, yellow sapphire and red pearl belong to friendly planets and can be worn together. Similarly, blue sapphire, diamond and emerald are influenced by friendly planets and make a good combination.
When gemstones are used or appreciated for their mystical properties, it is generally for their positivity or ability to influence an optimal outcome. However, through the centuries, some gems have acquired a reputation for being unlucky to the owner, including opal, black diamond and pearl.
The Hope Diamond
Arguably the most famous and most cursed precious gemstone in history, this 45.52-carat sparkler has a long and storied past. The Hope Diamond has been blamed for a laundry list of tragedies, including but not limited to: beatings, stabbings, murder, insanity, and suicide.
According to legend, the Koh-i-Noor Diamond only brings bad luck to men, with every male possessor historically losing his throne. The English royal women, free of its curse, have claimed the gemstone. Nowadays, you can see the stunning oval diamond on display in the Tower of London as part of the Crown Jewels.
Yellow Sapphire Stone: The yellow sapphire is one of the most powerful gemstones for attracting wealth and prosperity. Wearing this gemstone brings good fortune and prosperity to those who wear it.
We suggest wearing no more than three at the same time, and they work best when they are different lengths. The exception is Lavender.
That being said, rubies are considered to be one of the most powerful stones, packed with a fire that connects directly to the Root Chakra (the very base of your body's energy flow).
In Astrology, there are two gems which are the most powerful and dangerous at the same time. Among these, the first one is Neelam (Sapphire) and the second is Heera (Diamond).
If you swallow particles of these gems, their dissolution in your stomach could release impurities in the mineral. Certain gems may react dangerously with stomach acid to produce hydrofluoric acid (HF) or hydrogen sulfide gas (H2S).
The softest stones include talc (1), gypsum (2), calcite (3) and fluorite (4). The line between harder and softer gems is generally thought to be a Mohs rating of 7, where gems with a hardness of 7 or more are suitable for rings, while those below 7 are not.
Gemstones can have both external and internal flaws, often called inclusions. External flaws commonly found in precious gemstones are scratches, blemishes or minor chips. Internal flaws are also often found, and are like the fingerprint of a gem; each gemstone has its own unique internal structure.
