What Is a Diamond Shape?keyboard_arrow_down keyboard_arrow_up
Diamond shape refers to the geometric appearance of a diamond. Diamond shapes are categorized into two groups: round diamonds and fancy shape diamonds. Round diamonds, also known as round brilliant cuts, are the most traditional diamond shape. Fancy shape diamonds refer to any diamond that is not a round brilliant. Tiffany fancy shape diamonds include princess, cushion, emerald, oval, pear, marquise, heart and our exclusive Tiffany True® diamond.
What Is the Difference Between a Diamond Cut and a Diamond Shape?keyboard_arrow_down keyboard_arrow_up
It’s important to note that diamond cut and diamond shape are not the same thing. A diamond’s cut determines how its facets interact with light. A shape describes the geometric appearance of a diamond. Cut defines what the shape of a rough diamond will be—not the other way around.
This is why diamond shapes are often interchangeably referred to as cuts.
How to choose the Right me
Focus first on determining your fiancée's style, and then finding the right metal and color to complement that style. One of the first things you need to think about when choosing a metal for a setting is the type of jewelry your future bride typically wears:
If she’s drawn to cooler hues and silver-toned jewelry, then platinum or white gold is the way to go.
Yellow gold or rose gold are good choices if she tends to gravitate toward warmer tones.
Mixing metals like white gold and yellow gold is a smart option, because it will allow her to complement any piece in her existing jewelry wardrobe.
Which Diamond Shapes Sparkle the Most?keyboard_arrow_down keyboard_arrow_up
All Tiffany diamonds are exceptionally cut to maximize brilliance. However, each diamond shape has its own unique cut and faceting style which produces varying degrees of brilliance. There are three different diamond cuts used to craft every diamond shape: brilliant cut, step cut and mixed cut.
What is a GIA diamond?keyboard_arrow_down keyboard_arrow_up
A GIA diamond is really shorthand diamond sellers use to describe diamonds that have been graded by GIA. GIA is an independent, nonprofit organization that conducts gem research, educates gem professionals and sets the standards for determining diamond quality. One of GIA’s main functions is the grading of diamonds. You may have already heard or learned about the 4Cs of diamond quality: color, clarity, cut and carat weight. GIA created this standard, along with the scientific procedures for evaluating each “C” and the grading terminology used to describe them.
GIA does not mine diamonds, nor does it buy, sell or trade them commercially. It doesn’t appraise diamonds and is not otherwise involved in diamond pricing or valuation. GIA operates independently of these commercial interests, ensuring that its diamond quality assessments are completely objective and unbiased.
