Diamond Terms X, Y and Z

~ Diamond Terminology from A to Z ~

There are thousands of terms being used in today's jewelry industry. Some common knowledge, others are obscure and baffling. We've created a database of terminology from A to Z to make it easy, and of course if you still have questions, please do not hesitate to send us an email or give us a call.

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

X-Ray, Xray

Finding a diamond in a rough can be a daunting task. However if you pass the rough diamonds under an X-Ray the diamonds will show a glow or hue, sometimes referred to as fluoresce due to fluorescence. Usually in a yellow or blue color. Once they see this, they know there's a diamond in there.

Y.A.G, YAG

Yttrium Aluminum Garnet. It was used as a diamond simulate before Cubic Zirconia was discovered. It, however, was not a good substitute and the difference by today's standards could be easily seen.

Yellow

On the color scale of diamonds starting with D and ending with Z you slowly see the amount of yellow in each stage get greater and greater till eventually you have a champagne color. In diamond grading standards the more yellow the less valuable it is, but only Dull, Lifeless yellows. The Dull yellows will be found in the traditional diamond color scale. However once you get out of the scale you'll come across the fancy color Yellow. It's vibrant and full of life. Fancy colored diamonds, real ones not the artificially enhanced colors, will usually command quite a pretty penny in the diamond market due to it rarity. Same with the blues, reds, greens and oranges.

Zinnia

It's a type of flower cut discovered and used by De Beers.

Zirconia

Technical definition is a white solid used in ceramic glazes and refractory coatings, and as a synthetic substitute for diamonds in jewelry.

The diamond definition is somewhat different. Zirconia, depending on how well it's made, can really be a great substitute for diamonds, however it lacks a certain "livelihood". At a distance it looks like a diamond, and it could even possibly fool you if you're close. If you inspect it,though, and really look at it, you'll see something in most traditional simulates; the diamond looks perfect, but without the fire and brilliance that naturally occurs in real diamonds when you turn your hand and the light hits the diamond.
