you first must know the color of the Opal (i read this on a website called opal.com)
The numbers are probably an indication of the purity of the gold. Pure gold is 24 carat but 22 carat, 18 carat, 14 carat and 9 carat are all common.
The absolute value of 9 is 9. the absolute value makes a number positive |9| 9 is already positive.
Absolute value of -9 is 9.
The absolute value of -9 is 9 .
Its value is 9 hundredths = 9/100
Depends on the weight and workmanship of the ring.
Almost 3.75 ounces of gold.
You can't. The carat value is it's purity.
The Royal Mint does not issue 9 carat gold coins.
This is just the jewellers mark, it doesn't have any affect on the value of the gold. The numbers which have meaning and affect the value are: - 333 (8 carat / 33.3% gold content) - 375 (9 carat / 3.75% gold content) - 417 (10 carat / 4.17% gold content) - 585 (14 carat / 5.85% gold content) - 620 (14.8 carat / 62% gold content) - 750 (18 carat / 75% gold content) - 800 (19.2 carat / 80% gold content) - 875 (21 carat / 87.5% gold content) - 915 (22 carat / 91.5% gold content) - 990 (24 carat / 99% gold content) - 999 (24 carat / 99.9% gold content) The most common gold content used in modern jewellery is 3.75% (9 carat).
pure gold is 24, so 9 carat means 9/24 of the material is gold
24 Carat == pure ( ~100% )Therefore 9 Carat 0.375 pure.So to find the weight of gold in a 9 Carat thing, weight in grams X 0.375 == pure gold grams.easy, right? ;-)
9 carat is 37.5% gold, rest is base metal or alloy.
pure gold is 24, so 9 carat means 9/24 of the material is gold
9 carat gold is a low quality gold. Fourteen and twenty four carat gold is the most commonly used quality in jewelry.
