Diamond Color. How to Evaluate Diamond Color

Posted by khcreations on February 15, 2010 at 10:15 AM Comments comments (0)

Diamond ColorDiamond color is one of four major characteristics that are consideredwhen determining a diamond's quality and value. They are known as theFour C's, and the remaining three are clarity, cut, and carat weight.Understanding these four diamond characteristics and how they interactcan help you select a diamond that suits your tastes and yourpocketbook.


Diamond Color Variations

Diamonds are not all truly colorless, but it's the colorless diamonds, sometimes called white diamonds, which all other shades are judged against.

The Gemological Institute of America (GIA) has devised a set ofguidelines to grade diamond color. The color of graded diamonds iscompared to the color of control stones, preselected gems of a specific color.


 

Diamond Color Grading Procedure

*To be graded, diamonds must be loose stones, because once a diamond is set into metal the metal can affect its color.

*Diamonds are placed table-down, pavilion-up and viewed with a 10X loupe.

*A lettering system from D to Z is used to identify theamount of color present in each diamond, with D awarded only to rare,totally colorless diamonds. 


Diamond Color Grades

Colorless diamonds and diamonds that are yellow or yellowish brown aregrouped into the categories shown below. These grades do not apply to fancy colored diamonds--they have their own color grading standards.


D-E-F

Colorless.


G-H-I-J

Nearly colorless.


K-L-M

Faintly tinted, usually yellow.


N-O-P-Q-R

Lightly tinted, usually yellow. Tint can be seen with the naked eye.


S-T-U-V-W-X-Y-Z

Tinted, usually yellow, may progress to brownish. Tint visible to the naked eye, even when mounted.


Other Factors Affect Diamond Color


Fluorescence

GIA diamond reports and many other lab reports indicate whether or not a diamond exhibits fluorescence,which means the diamond's color changes when it is exposed toultraviolet radiation. Since UV radiation is a component of daylightand is also present in fluorescent lit rooms, diamonds with thischaracteristic can appear to change color quite often.


*Diamonds that produce a blue reaction usually appear whiter, or more colorless, under UV light.

*Stones that fluoresce yellow appear even more yellow under some lighting conditions.


Diamond Color Treatments

The color of a some diamonds can be dramatically changed by using HPHT (high pressure/high temperature) processing. Unlike diamond treatments used in the past, HPHT changes appear to be permanent.

Coatings are sometimes used to temporarily enhance a diamond's color.


 

Choose Settings that Enhance Diamond Color

A loose diamond that appears lightly yellow to the naked eye willusually appear more colorless when mounted in a white setting--platinum or white-gold. Mounting the same diamond in yellow-gold metal usually enhances the diamond's yellowish tone.


Summing Up Diamond Color

A diamond's color grade affects its price, but it isn't the most important diamond characteristicto consider before purchasing a diamond. If your budget prevents youfrom buying a D through F graded diamond it does not mean you can't owna beautiful gemstone.

Diamond grades G through J can be fine gems and other grades may beperfectly suitable. An experienced jeweler can help you evaluate andselect the best diamond for your needs.

A professional cleaning every six months will keepyour platinum jewelry in great shape.Store your platinum jewelry separately and with care, not allowingpieces to touch each other, because even platinum can be scratched.Signs of wear, such as scratches, can eventually appear onplatinum. However, due to the metal's durability there is usuallylittle metal loss from the scratch. If visible scratches do appear,your jeweler should be able to re-polish the piece. If your platinum is set with diamonds or other precious stones, beespecially careful, as these materials can be more susceptible todamage. Some fine jewelry pieces combine platinum with karat goldjewelry. Care for these pieces as you would your gold jewelry, orconsult your jeweler.

Place cultured pearls in a chamois bag or wrap them in tissue when putting them away. Cosmetics, perspiration, oils and ordinary wear weaken and stretchthe threads on which the pearls are strung. Bring your pearls back toyour jeweler for restringing once a year. Make certain the pearls arestrung with a knot between each pearl. This will prevent loss of pearlsif the string should break.

HOW TO MAKE A PHOTO BOX

Posted by khcreations on March 17, 2009 at 10:21 AM Comments comments (0)



I've noticed that a lot of people (in general)
could use this method.

ITEMS YOU NEED


12x12x12 box
14 x 10 piece of plexy glass or glass
a knife
background paper (scrapbooking paper is great from craft store)
wax paper
60-100 watt light

How to put it all together:

1) Take your 12x12x12 box and cut out one side. Keep the bottom of
your box intact.

2) (open side you just cut out) Measure 9 inches from the bottom and
make a slit all the way to the back of the box on both sides. Do not
cut the back of the box.

3) Slide your glass into the slits of the box

4) Take the wax paper and tape it over the light source. The
wax paper is used to defuse the light.

5) Aim the light towards the opening of your box.

6) Lay your background on the bottom of your box as your background.

7) Shine your light into to open area of the box. Take your photos from the

back of the box... with the light facing you.

Your camera should focus on the jewelry or small object. The
background will be fuzzy due to the distance of the background from
the object.

How to Avoid Fake Gemstones when You're Looking for the Real Thing

Posted by khcreations on March 10, 2009 at 8:58 PM Comments comments (0)
Call them what you like: faux or fake gemstones, imitations, or simulated gems -- they all have one thing in common, they can look just like the real thing, but they do not have any of the physical characteristics of the natural or synthetic gemstone they are meant to represent.

Faux gems can be a very good option, because they give us an inexpensive way to wear colorful, lush-looking jewelry without the hefty price tag that comes with the real thing. There's no reason to avoid faux gems -- what you do want to avoid is paying too much for misrepresented merchandise.

Materials Used to Make Faux Gemstones

  • Today's imitation stones are often made of glass or plastic. A jeweler can easily detect those materials, so have the jewelry inspected if you think you might have purchased a fake.

  • A real gemstone can be mounted in a solid-back setting, with foil placed underneath the gem to make it look more brilliant or change its color.

Composite Gemstones

Composite gemstones are made from a small piece of a desirable, genuine stone that's combined with an inexpensive or imitation gemstone. Opal jewelry is often with composites.

Doublets are composite stones made with a large, inexpensive chunk of some kind that's topped by a thin slice of a desirable gemstone. The division usually isn't obvious until you look at the piece under magnification.

One type of doublet is assembled by sandwiching a colored bonding agent between two clear, inexpensive stones -- the added hue makes it look like a colored gemstone.

Triplets are composites that are assembled in three parts instead of two.

Creative Gemstone Names Can be a Signal

Descriptive terms are sometimes used before the name of a gemstone, like Oriental emerald (a green sapphire). An American ruby is a garnet. Australian jade is treated quartz. Question the authenticity of any gemstone that's advertised with an extra, descriptive name.
