Diamond Certificates

There are dozens of gemological laboratories handing out certificates but only a few are respected by the diamond trade. Some well-known laboratories include the European Gemological Laboratories (EGL) and the Gemological Institute of America known as GIA

To better understand your certificates here are some commonly used terms

Stone ID: A Unique number representing your diamond. This number is registered in a global database.

Date: The date the report was issued.

Cut and Shape: Shapes other than the standard round brilliant are called fancy shapes or fancy cuts. Their names are based on their shapes. The best known are the heart, marquise, pear-shaped cut, emerald cut, princess cut, oval, and radiant.

Dimensions: The dimensions of the diamond are stated as “largest diameter – smallest diameter X depth” for round shapes and “length X width X depth” for other shapes.

Carat Weight: The standard unit of weight used for gemstones. One carat equals .200 grams (or 200 milligrams). Usually abbreviated ct.

Graining: Graining and grain lines reflect irregularities in the crystal structure. Colorless graining usually does not affect the clarity grade; but white, colored, or reflective graining does.

Proportions: Proportion refers to the angles and relative measurements of a polished diamond. More than any other feature, proportions determine a diamond’s optical properties. Studies have shown that table size, crown angle, and pavilion depth have a dramatic effect on a diamond’s appearance.

Depth%: The depth of the diamond divided by the average diameter for rounds, or the depth divided by the width of the diamond for other shapes.

Table%: The average size of the table facet divided by the average diameter of the diamond for round shapes, or the width of the diamond for other shapes.

Girdle: The girdle is the outside edge of the outline of the diamond. The certificate indicates the thickness of the girdle relative to the size of the diamond, and the condition either polished or faceted.

Culet: The point at the bottom of the diamond. If the culet is faceted then the certificate indicates the size of the facet relative to the size of the diamond.

Finish: Finish grades represent the quality of the diamond’s surface condition (polish), and the size, shape and placement of the facets, including the evenness of the outline (symmetry).

Polish: Indicates the care taken by the cutter in shaping and faceting the rough stone into a finished and polished diamond.

Symmetry: A diamond’s symmetry is the arrangement of the facets and finished angles, created by the diamond cutter. Excellent symmetry of a well-cut and well-proportioned diamond can have a great effect on the diamond’s brilliance and fire. Grading reports will often state the diamond’s symmetry in terms of Excellent, Very good, Good, Fair, or Poor.

Cut: The proportions and finish of the diamond. With the proper proportions, most of the light that enters a diamond is returned revealing the diamond’s brilliance and fire. Any deviation of these proportions will compromise the beauty of the stone.

Clarity: Clarity represents the relative absence of inclusions and blemishes in the diamond. Clarity is graded under 10X magnification from Flawless to Included based on the size, nature, position and quantity of the diamond’s inclusions.

Color: Assesses to an obvious yellow (Z) when compared to Master Color diamonds.

Pavillion: Depth The distance from the bottom of the girdle to the culet is the pavilion depth. A pavilion depth that is too shallow or too deep will allow light to escape from the side of the stone, or leak out of the bottom. A well-cut diamond will direct more light through the crown.

Tolkowsky Ideal Cut: In the 1920’s a Russian Mathematician by the name of Marcel Tolkowsky calculated the proportions of the facets in a round diamond that would bring an ideal balance between brilliance and dispersion. Any deviation from these designs will compromise the beauty of the stone.

Fluorescence: When exposed to ultraviolet light, a diamond may exhibit a more whitish, yellowish or bluish tint, which may imply that the diamond has a property called fluorescence. The untrained eye can rarely see the effects of fluorescence. Diamond grading reports often state whether a diamond has fluorescent properties. Fluorescence is not considered a grading factor, only a characteristic of that particular diamond.

Crown Height: The crown is the upper portion or the top of a diamond.

Diagram: A diagram approximates the shape and cutting style of the diamond. Symbols on the diagram include the type, nature, position and approximate size of a clarity characteristic.

Get Dreamy Jewelry

Whatever your thoughts and imagination, let’s look at some possibilities.

Picture yourself wearing just the right piece of jewelry for you – a necklace, bracelet or earrings that you look at and say “Wow! That has to be for me!”. There’s something in your heart that is drawn toward it and your eyes focus on the beauty of it. There’s a special appeal, maybe the creative design or a particular gemstone, pearl or crystal. You know how much you want that piece of jewelry and then, guess what! The inevitable question arises! “What am I going to wear with it?” It’s not a case of purchasing a piece of jewelry to go with an outfit anymore but the desire is so strong that the outfit has to go with the jewelry! Does that sound a familiar story?

Now let’s see what jewelry we can place under the category of ‘dreamy jewelry’.

Think about the possibility of having a genuine gemstone necklace, bracelet or earrings. Can you see yourself dreaming about owning genuine gemstones and feeling special because you know you are wearing genuine gemstone? I personally, have always felt drawn to genuine gemstones rather than a stone that I’m not sure even has a name, not to mention any value!

Some of the colors and types of gemstones are simply stunning. Here’s a few for you to ponder. Turquoise, rose quartz, agate, amethyst, garnet, jade. There are so many colors and shapes available.

Gemstones can be used in many combinations of both style and color, giving a unique appearance to your jewelry. Isn’t it nice to be able to view your jewelry as unique? Let’s face it, none of us want to walk down the street or into a shop and see every second person wearing the same necklace, do we?

Another possibility with ‘dreamy jewelry’ is to have pearls mixed with gemstones. With the vast array of pearl colors and shapes available, once again you can have a unique necklace, bracelet or earrings that is truly ‘dreamy’.

Info about Jewelry for Men

Men’s rings come in wide range of shapes and sizes. Most men’s rings are wider and bolder than women’s rings. The modern man may choose a ring made of titanium or stainless steel to really make a statement. Gold and Platinum are popular types of metal for more expensive men’s rings. Men’s rings are usually inscribed or molded with unusual decorations as well. There are some clubs which men belong to such as the Masons or the Elks that use rings with symbols on them to declare status or enrollment.

Jewelry for body piercing can be very simple or very bold. Most men will have a pierced ear with a simple gold or silver ring. There are also eyebrow rings, nose studs and rings, belly button rings and jewelry for other more risqué body piercing. The tendency for some men with piercing is to stretch the piercing so that they can insert jewelry with a bigger gauge and it looks bolder.

Men’s necklaces also come in many shapes and styles. Most men prefer to wear a necklace in dark or neutral colors that won’t stand out. Necklaces can be beaded or made of some natural substance like shells or glass. There are also gold and silver necklaces available for guys who want a little flash in their wardrobe.

Men’s jewelry is quickly growing in popularity and fashion. There are certainly other kinds of men’s jewelry beyond the types listed here and it’s available for any sense of style and taste a guy can come up with.

Titanium Ring Resizing

· Grade of Titanium

· Is it diamond set?

· Does it have a precious metal inlay?

· Does it need to go up or down in size.

Whilst it isn’t normally within the capabilities of a normal jeweller to do a quick resize, there is often various options that the manufacturer can take.

Grade 2 commercially pure Titanium is fairly ductile and will stretch and compress quite readily. If it has a precious metal inlay set into the outside it is probably better to take a skim out of the bore to make it bigger – stretching will normally cause the inlay to split. The amount of increase could be up to about two sizes. Compressing a ring with an inlay is usually OK for about one size. Compressing plain rings depends on the outside pattern. If it is patterned then the amount of force required to compress it will undoubtedly cause too much damage to repair the outer surface economically and so should be avoided. Plain domed or flat rings don’t present much of a problem.

Higher tensile grades of titanium, such as aircraft grade Ti/6Al/4V (or grade 5 as it is also known) will not stretch or compress. The only option with these is to increase the ring size slightly by remachining the bore larger.
