What is the difference between Carat and Karat?

A carat is a unit of weight for diamonds.  One carat = 200 milligrams.  There are 100 points in a carat.  A karat is a measure of purity of gold.  14 karat gold means 14/24 or more than 58% pure gold. 18 karat gold means 18/24 or 75% pure gold.

How do you qualify value in karat gold jewelry.

Four features determine the value of an item of gold jewelry:  karat, construction, production, weight.  The higher the pure gold content and the great the weight , generally the greater the value.  The cost to produce an item of jewelry is reflected in the production cost.  The cost per item to manufacture a mass produced item is significantly less than the cost per item to produce a limited or custom design.  The construction cost refers to the fact that all jewelry is not made the same.  The labor that goes into creating an item  is reflected in an item's value.  Manufacturer's vary their cost based on the time and effort it takes them to produce an item.  Items of jewelry constructed in several steps or that require hand assembly will generally cost more than items made by machine.

The last feature I would like to discuss is factory seconds.  Jewelry manufacturer produce items below their acceptable standards.  These items are typically sold at a discount.  Unfortunately, these items are rarely market as seconds.

What is Mohs Scale ?

The Dictionary of Gem and Gemology defines Mohs scale as: "The most commonly used scale of relative hardness of minerals. - diamond 10, corundum 9, topaz 8, quartz 7, orthoclase feldspar 6, apatite 5, fluorite 4, calcite 3, gypsum 2, talc 1.  Division are not equal, minerals representing various harnesses having been chosen arbitrarily by the mineralogist F. Mohs.  The difference between 9 and 8 is considerably greater than between the lower numbers and between 9 an 10 is greater than between 9 and 1."

Are the colors of the gemstones accurate in your Pictures

Unfortunately, the color saturation in the pictures is not as accurate as I would like.   The sapphires and emeralds appear darker in the jpeg images then they actual are.

What is Electroform jewelry?

Electroform is the process by which an electric current is used to deposit metal into a mold.  Electroform jewelry is typically hollow and light.  It is used frequently in the production of earrings and pendants typically ones that appear heavy or large to the eye.    The process was developed by Morris Hartman Von Jacobin in 1838.

If my watch is water resistant can I wear it in the shower or go swimming with it?

Watches marked "Water resistant" should never be worn while you are engaged in either of these activities.  "Water resistant" watches should be fine if you are caught in the rain but should never be subjected to more demanding use.  If you want to wear your watch while swimming I recommend  a watch that is water resistant to 50 meters.  If you go snorkeling you'll want a watch water resistant to 100 meters.  If you go recreational diving I recommend a watch water resistant to 200 meters.
