Trilliant diamond shape

trilliant diamondTrilliant diamonds can be found under the name Trillion, Trielle or Triangular brilliant diamonds, although there's a small difference in shape among these names. The triangle looking diamond shape can be accomplished by curved or flat sides, resulting in a significant difference to an observer. Triangular shaped brilliants can be categorized under two main groups: Trilliant diamonds with slightly bowed sides branded by Henry Meyer Diamond Company, and Trielle diamonds with straight edges protected by Trillion Diamond Company. Trielle or Trillion diamonds are less popular so the article will stick to the well-known representative of triangular shapes: Trilliant diamonds. The shape itself is pretty simple, 3 curved or straight sides are symmetrically arranged to reassemble an ideal triangle. The points can be rounded or sharpened, which perfectly fits if Trilliant is placed next to the side-stones.

It's uniqueness is evident when the diamond shape is observed, some cutting specifications are just not conventional for brilliant diamonds. The facet number for Trielle is 50 and 31 for Trilliant, the fewest among brilliants that average around 56 facets. One of the reasons is selecting the thin rough stones for Trilliant shape. Techniques of modern diamond cutting have been known for almost a century, Trilliant has been created in the early 60s as fancy shapes became popular. The most important feature is a fully uncovered surface of diamond from it's setting allowing the brilliance and fire to emphasize. An imperfection visible due to accentuated sparkle are blemishes appearing because of the shallowness of a thin diamond stone. The natural characteristics of a crystal structure will define Trilliant in the first place- polish and symmetry don't depend just on cut quality.

As it's case for many diamond shapes, the home of Trilliant diamond is Amsterdam. The impeccable form is what makes Trilliants so expensive. A cutter must make an equilateral triangle with exact 1:1:1 length proportions. An irregular ratio will decrease the value of a diamond. The angles between two sides of the diamond, next to the length of each three sides, are accurately measured to create an ideal triangle. Each inequality of the angles or side length would make a Trilliant shape look irregular. The corners tend to be rounded, in case they are pointed, an adequate protection should be applied when mounting a diamond on the setting. The depth of Trilliant diamonds varies around 35-40% depending on the flatness of the shape. Its impact on brilliance and sparkling effect is indubitable, but the actual percentages- just like width or when choosing shape, are a matter of buyer preference. The lowest depth seen on Trilliant cut diamonds, 32% isn't an astonishing depth so we can often find such Trilliants as side-diamonds. Upper limit is 44%, the diamond looks fancy and shows its true fire. The dispersion is the decisive parameter for most people when selecting a diamond. A crown to pavilion depth varies around 50% in most cases.

Uncurved Trielle diamonds weighing less than 1 carat and cut in matching pairs are suitable for accent stones, like Princess or Cushion. Curved Trilliant stands better as the solitary center stone. Diamonds sold in pairs are seen on pendants and stud earrings, and they get a better price and achieve an impression of an expensive jewelry piece. Points of Trilliant diamonds should be protected by settings. Engagement rings, wedding bands, bracelets, and necklaces are some of the uses of a Trilliant diamond, making this sparkling shape that symbolizes the energy spread all over the jewelry pattern.
