An emerald is a precious stone.
The term 'Semi-precious gemstone' is an old one that referred to any gem that is not diamond, ruby, sapphire or emerald. In modern times, this distinction does not reflect a gemstone's value, some semi-precious stones can be worth more than precious ones.
Diamonds used in jewelry are Precious. other diamonds are not even semi-precious
Moderately. And that depends on the quality of the stone. They are semi-precious stones- not as expensive as diamond, ruby, emerald, but not costume jewelry either.
diamond or emerald
5 precious stones I know are the Diamond, Ruby, Emerald, Sapphire, and Opal.
The Ruby is more expensive.
Precious is a judgement and you are the judge. Individually, each gemstone is valued monetarily on its own merits; precious includes sentiment.

Gravel. I don't agree. Precious stones are Jewels: Diamond, Ruby, etc. "Semi-precious" refers to Jade, Opal, Turquoise, etc.
The difference between a gem a jewel and a semiprecious stone is minimal. A gem is a stone of value such as a diamond, but it may be in its raw state. A jewel is a finished gem, one that has been worked t make it show its desirable qualities Semiprecious stones are gems that are considered to be of value, but do not have as high a value as the major gems such as diamonds and rubies.
