The specific gravity of opal typically ranges from about 1.98 to 2.20, depending on its water content and composition. This variation is due to the presence of silica and water within the opal structure. Opal's unique properties, including its play-of-color, can also influence its specific gravity slightly. Overall, it is generally lower than that of many other gemstones.

What is bauxite's specific gravity?
The specific gravity of bauxite typically ranges from 2.2 to 2.5.
Does specific gravity affect hydrostatic pressure?
Yes, specific gravity does affect hydrostatic pressure. The hydrostatic pressure exerted by a fluid is directly proportional to the specific gravity of the fluid. A fluid with higher specific gravity will exert greater hydrostatic pressure at a given depth compared to a fluid with lower specific gravity.
What is specific gravity of sapphire?
Approx. 4,0-4,1.
What are diamond's specific gravity?
3.52 > tolerance: ±0.01
Is altitude affect to specific gravity and density?
Yes, altitude can affect specific gravity and density due to variations in atmospheric pressure. As altitude increases, atmospheric pressure decreases, leading to a decrease in density and specific gravity of gases and substances. This is important to consider when measuring and calculating these properties at different elevations.
How heavy is opal?
Opal's weight can vary depending on its type and water content, but it generally has a specific gravity of about 1.98 to 2.20. This means that opal is lighter than many other gemstones, such as diamonds or sapphires. The weight of a specific opal piece can be determined by its size and density, with common sizes ranging from a few carats to several hundred carats.
What is the form of Opal?
Opal has no definitive form. The word used to describe opal is "amorphous" which means: lacking definite form - having no specific shape.
What is the weight of 10 carots total weight marquise cut loose opal lot Each opal measures approximately 4x2mm?
The is one factor missing .... how many stones make up the 10 carat total ? without this , the question is nonsensical. Rod Keady Actually, carat is a measure of weight already. It is the same as 200 milligrams. So 10 carats would be 2 grams. That is not a lot. Opal has a specific gravity around 2, so that means it has twice the density of water. Two grams of water is about 2 cubic cm, so 2 grams of opal would be about 1 cubic cm volume. Since some opal has a specific gravity of up to 2.25 or so, the volume of opal could be as little as 0.88 cc. That means, however, that you have quite a few of these small opals. Probably as many as 20 or 30 -- maybe more. Since they were cut, you really only have a small slice of opal in each cut, topped by a cabochon of crystal quartz. The specific gravity of quartz is higher than that of opal, which probably reduces how many stones you have, but still, you should have quite nice number of them. 4mm x 2mm is the perfect size to set in a ring or in earrings.

What is the identity of the gemstone Opal Diamond Garnet Topaz?
To learn the identity of the gemstones opal, diamond, garnet, and topaz you need to look at their color, transparency, specific gravity. You need to light the stone's surface and look through a loupe. You also need to determine the birefringence and refractive index.
What is the specific gravity for aluminum?
Aluminum has no specific gravity, at least by the current definition of gravity.

What is the density of an opal?
The density of opal typically ranges from 1.9 to 2.3 g/cm³, with an average density around 2.1 g/cm³. This can vary depending on the specific type and composition of the opal.
What type of luster does a Opal have?
Opal typically exhibits a vitreous to pearly luster. This unique luster contributes to its vibrant play-of-color, making opals highly sought after in jewelry. The luster can vary depending on the type of opal and its specific characteristics.
Are there different kinds of opal?
The types of Opal that i am familiar with are White Opal, Fire Opal, Boulder Opal, Black Opal, Crystal Opal, Light Opal, Doublet Opal, Triplet Opal, Common Opal, Synthetic Opal, and Immitation Opal.
