The difference between what one person calls a semi-precious stone and another calls a precious stone varies! It has to do with the clarity, rarity, and the hardness.
One opal may be extremely beautiful. It may fetch an extremely high price. It is still considered semi-precious because it has a hardness of 6. A ruby is precious with a hardness of 9 and a diamond with a hardness of 10. At one time a clear stone with a hardness of 8 and above made it precious.
A flawed diamond with a hardness of 10 could only be used for industrial purposes and was not a precious stone.
the difference is that preciose is a smaller sided one
rare and beautiful gemstones are called precious stones. gemstones that are more common are called semiprecious stones. because they are beautiful and long lasting, many precious and semi stones are usef to make jewelry.
Diamonds, rubies, sapphires, and emeralds are precious stones that are often made into gems. Opal, amethyst, turquoise, topaz, garnet, aquamarine, and jade are some semi stones that made into stones.
The World Jewellery Confederation (CIBJO) no longer recognises the terms 'precious' or 'semi-precious'. A gemstone is a gemstone! Prior to the development of commercial pearl cultivation in the early 20th century, pearls were very rare and considered amongst the most precious of gems. Today, with mass cultivation of pearls from Japan, China, Australia and other parts of South East Asis, consumers are able to purchase pearls at a variety of price points from under $100 to many thousands of dollars depending on size and quality.
precious
A gem is a mineral or organic material that is cut and polished for use in jewelry or other decorative items. A jewel specifically refers to a precious gemstone, such as a diamond, ruby, sapphire, or emerald. A semi-precious stone is a category of gemstone that is not as rare or valuable as precious stones, such as amethyst, turquoise, or garnet.
Jewelry made with precious and semiprecious stones are some uses of igneous rocks. Granite is often cut into blocks to use as building blocks, or countertops.

Some green semiprecious stones are: Emerald Oro Verde Tsavorite Malachite
A diamond, ruby or sapphire is said to be a "precious" stone. An amethyst is said to be a "semiprecious" stone. Semiprecious objects are therefore less valuable than precious ones.
Diamonds, rubies, sapphires, and emeralds are the precious gems, all others are semiprecious
Her ring has several semiprecious and precious stones. Semiprecious stones are not as valuable as precious stones.
precious
Semiprecious metals and gems have characteristics of precious ones, but are not totally the same
precious gems are rare and valuable and the semiprecious are not as rare
Semiprecious refers to gems having value, but not precious.
Semiprecious refers to gems having value, but not precious.
Because it is not an extremely rare gem stone.
Depends cut or just dug out of the ground? Cut is just a bit more but dug is cheaper. In jewelry or out? If it's in gold or silver it is worth more of course. But all in all its about midway between both (confusing I know) like 75% precious instead of 50% (semiprecious).
My favourite semi-precious stone is the Amethyst.
Ruby is a precious stone.
