solitaire District Tips - What's the Best solitaire Substitute?

Many will say that there is no substitute for a diamond, and they may be right. A diamond's brilliance is unparalleled, and it is the hardest stone in the world. Fakes can impress, but only for so long. Here are some alternatives, however, if you can't afford a diamond, or if you don't want to supervene tradition, and prefer instead to blaze your own marital trail.

1. C.Z.: In the 80s cubic zirconium was advanced and became a sensation. Unfortunately, these artificial stones don't wear the way a diamond does, losing their luster and scratching over time. They do score a 9 on the Mohs hardness scale, however, and at a carat, they're hard to beat pricewise.

2. Moissanite is significantly more expensive, at 0 per carat, but is still about 1/10 as costly as a diamond. Moreover, it's approximately impossible to tell the variation in the middle of this manmade version of a meteorite mineral unless you look at it under a microscope. It has a hardness of 9.25 compared to a diamond's 10, but the moissanite has double refraction lines, and a diamond has single, which is the reason the artificial stone looks more brilliant.

3. Goshenite: Also known as white beryl, this stone is just as brilliant as white topaz on the refractive index. While it's an 8 on the hardness scale, you can in fact customize a ring with a goshenite set.

4. White topaz: This stone is semi-precious, and since it is not as hard (8), it will scratch more in fact than a diamond. You can most likely afford a much larger white topaz for the price you would pay for a teeny diamond.

5. White sapphire: One of the four most costly stones, this is the second hardest mineral after the diamond. Although looking a quality, top grade white sapphire is rare, it won't be as costly as a diamond. Blue sapphires are similarly precious, and just as beautiful.

6. Tanzanite: This pretty stone is blue and violet and shimmers in translucence. Discovered in 1967, this stone was named after the only country in the world where it is found.

7. Emerald: an additional one one of the four costly stones, the best conditioned green and gorgeous emeralds can be more costly than diamonds.

8. Ruby: Because it is red, the associations with passion and emotion are clear. Like the emerald, this costly stone in its rarest form it is exceptionally hard, brilliant and bright.

Many gems are proper for taking the place of diamond engagement rings. All that matters is that the ring matches the wearer's tastes, and that there is symbolic meaning behind it. Talk about an engagement ring before buying it for your fiancée. Love shouldn't be grounded in how much a ring costs, but instead what it means for the relationship and the time to come that lies ahead.

diamond Color - What's Its Grade?

Diamond color is one of the four grades used in determining the value of a diamond. The stones will occur plainly in a range of colors, but the most base one are the pure colorless diamonds.

Colored diamonds have color because of structural defects that cause the stone to discharge all but one color of the rainbow or in the case of black diamonds all the colors are absorbed. Because colored diamonds are rare and pretty they absolutely cost more than the clear diamonds, sometimes in excess of thousands of dollars for the same carat size.

Diamond

Diamond colors are, colorless, white, yellow, steel, blue, orange, green, pink, brown, and black. Any diamond with a color is referred to as a colored diamond, but if the color is very chromatic it will be classified as a fancy colored diamond. The most base of the colored diamonds is yellow.

The market classification of colored diamonds uses an alphabet system. The range of colorless to white can be identified as a letter fluctuating from 'D' through 'I'. A near colorless diamond may be identified as 'J' through 'L'. A faint yellow diamond will be an 'M.' A light yellow diamond can be classified as one of the letters 'N' through 'R' and the yellow diamonds in a range from 'S' to 'Z'. The other colors will all be classified as colored diamonds, for example a blue diamond is call a 'colored blue diamond' or if it's very blue, 'fancy colored blue diamond.'

On a side note a diamond can be colored on purpose with irradiation followed by heat treatment. There is a risk involved with being exposed to irradiated objects so it's not a recommended process. Also the color may change over time. It is required that color treated diamonds are sold as colored treated and sellers can't mislead the buyer.
