Since moissanite is slightly less dense than diamonds, it is better to refer to moissanite stones in terms of size. However, we understand that most people understand gemstones by carat rather than mm. Here is a chart: Note: For the list of corresponding carat weights to mm sizes for other moissanite stone shapes, please visit our loose moissanite stones page.

Since cubic zirconia is slightly less dense than diamonds, it is better to refer to cubic zirconia stones in terms of size. However, we understand that most people understand gemstones by carat rather than mm. Here is a chart:

In order to fit available settings, it is easier for retailers to order Moissanite by millimeter. The specific gravity of Moissanite is 3.21 grams per cubic centimeter, so a 6.5 mm round brilliant Moissanite jewel is approximately 0.88 carats. Because of its rarity, unmatched beauty, and patent protection, Charles & Colvard created Moissanite is expected to retain or increase its value over time.

The earliest gem traders measured their stones by comparing their weight to the weight of the pods from the carob, or locust tree. These tiny carob seeds are remarkably consistent in weight, and this is where the term 'carat' is derived from. The metric carat, which equals 0.20 gram or 1/142 of an ounce, is the standard unit of weight for diamonds and most other gems. One carat is divided into 100 "points." A diamond weighing 50 points = 0.5 carat (ct.), and is expressed as one-half carat

The uniformity of grit is critical to efficient sharpening. If you're using a coarse stone you want your grit to be uniformly coarse. If there is finer grits present in the stone it will not cut nearly as fast. If you are trying to finely hone your edge the presence of coarse grit in your stone will not allow you to achieve the fine edge you desire. Uniformity of grit size on your stone can be assured by purchasing high quality diamond stone products made by DMT®.

Yes, our DMT® diamond stones are made of diamond. However, these monocrystalline diamonds are not useful as jewelry. The largest and coarsest diamonds in the DMT® sharpening line are 60 microns in size. That is still very small.

I wore women's plus size 24/26 pants, and 26/28 shirts. (XXL & XXXL) I did not have a scale, but I was easily 290 pounds. There are pictures of me that size in my before pictures.

A diamond's weight is measured in carats. The weight is often stated in fractions of a carat. For example, 1/5, 1/4, 1/2 carat. A carat is divided into 100 points, so that a diamond of 25 points equals 1/4 carat and 50 points equals 1/2 carat.

Wow! Am I ever asked this question a lot. Not a day goes by that someone doesn’t ask me if they got the real thing. This question has been so popular I’ve devoted a whole article to all the tests and tricks you can perform on your stone to know if you got the “Real McCoy.” to be magically transported to the article. Hands down cubic zirconia (c.z.)is the most popular simulant on the market. There are two types: machine-manufactured and hand-cut.

We recommend water on diamond stones for lubrication and to wash away the swarf. It works well, it easy to clean up, and is readily available.

Always rinse your stones with water after use. Water will remove the metal filings left on the surface that could rust. After rinsing we always recommend drying the stones thoroughly so they can be stored dry. If your diamond stone becomes dirty you can use a tooth brush and a household abrasive cleaner to clean up the stones.

The answer is a resounding NO – Moissanite is not a substitute for diamond scientifically or emotionally. Charles & Colvard created Moissanite is a unique near-colorless jewel (SiC) that stands on its own when it comes to superb fire and brilliance. From a scientific standpoint, the Moissanite used in jewelry today is a created jewel that was originally discovered in its natural state in the Canyon Diablo meteor crater located in Arizona.

The carat weight and dimensions for each stone have been checked and double checked here at the Icgems.com inhouse laboratory. All of our gemstone measurements have been made in millimeters and the gemstone weight measured and reported in carats. A "carat" is the equivalent of one-fifth of a gram, and 25.4 millimeters equals one inch.

Weight distributing is based on the amount of loaded tongue weight the trailer has. To purchase the correct size weight distributing hitch (WDH), you will need to first load the trailer as you would tow it down the road and then have the tongue weighed. You can weigh the trailer tongue by using a bathroom scale or taking it to your trailer dealer to have the tongue placed on a tongue scale.

x 1.25" and less than an ounce. About the same size and weight as a car's alarm key fob (the keychain unit that unlocks/locks your vehicle's door).

SPIDER is huge and heavy, taking up as much room as the laser it purports to measure. This, plus the difficulty of aligning the beam into SPIDER, means SPIDER cannot be easily moved from laser to laser. A GRENOUILLE or UPM device, on the other hand, is very compact and light. It fits almost anywhere on your optical table, easily moves to where you need to use it, and the procedure for aligning the beam into GRENOUILLE is trivial.

Most plans require a committment to buy one pair. 3/3B Plan allows options to redeem one pair default diamonds or single piece of bigger carat diamond or diamond products. 123 Plan allows one to commit to one piece of Emerald Cut diamond.

Stamped concrete is merely concrete slabs with a pattern stamped into the surface. They are susceptible to the same problems of a concrete slab sidewalk or patio. Cracking due to freeze/thaw cycles may happen with a stamped concrete patio. Paving stones can be dismantled and repaired with the same product being used on the surface.

No. The standard GIA diamond color grading scale is not designed to rate Moissanite. Unlike diamonds, which range from colorless to brownish to fancy yellow, Charles & Colvard created Moissanite can have slight undertones from green to yellow to gray. It is a beautifully brilliant, highly dispersive jewel that stands on its own, creating a unique jewelry category.

Answer: Moissanite has very close characteristics to diamond. The refractive index or brilliance of Moissanite is 2.65 as compared to 2.42 for diamond. The dispersion or fire of Moissanite is 0.104 as compared to 0.044 for diamond. Moissanite is the second hardest jewel after diamond with a hardness rating of 9.25 as compared to 10 for diamond.
