The truth about one of the 4 C’s – Clarity

When you read the literature concerning diamond acquistion, the first thing you learn is that there are “4 C’s” that you need to understand in order to make an informed purchase. Those 4 C’s are Color, Clarity, Carat (weight), and Cut.

For “white” diamonds, the less color the better, with “D” stones considered colorless. Grading is usually done by comparing a diamond to a set of master stones.

Clarity is determined by identifying the number, shape, and positioning of inclusions inside the stone with a 10X magnifying device.

Carat weight is determined with a balance or scale.

Cut is a mathematical/geometrical calculation of the angles of the facets, and what they provide in the way of brightness and dispersion.

All of these factors have an influence on the price of a stone. In fact, though, in many instances, you can’t tell the differences between one stone and another costing 1/2 the price. I’ll give an example using the Clarity of a stone.

The number of inclusions and their placement in the stone affect the clarity grade. There are books available that demonstrate the relative affect a given inclusion will have on the grade. In fact, you could simply read a book on clarity and be able to grade clarity as well as most diamond salespeople. But what’s interesting is that the standard grading is done at 10x magnification. A stone graded at 10X may have 25 times more inclusions if viewed at 15X magnification, and may have no inclusions visible with the naked eye. Inclusions are present no matter what, but the grading is done at 10X.

But the price of a stone may be 50% higher to you, and the extra cost is for something you can’t even see. This happens when you jump from Internally Flawless to VVS, and from VVS to VS clarity grades. In some cases, even when going from a VS to a good SI1. It’s perfectly reasonable to care about the inclusions you can’t see, but often times people would rather put that money toward a bigger stone. Something to keep in mind.

Why some diamonds are sparkly and some are like mud

The Round Brilliant is the most popular diamond cut for a reason.

The way a diamond is cut affects its brilliance. Put your hands together palm to palm like you were going to dive or pray. Keeping the heels of your hands touching and your fingers and hands straight, spread the fingers of each hand away from each other. Looking at your hands now, they should be in a “V”.

Now pretend that the “V” represents the sides of a diamond. Imagine that light comes in from the top of the stone, the open part of the “V”. The sides of the “V” are actually facets that reflect light. If the stone is cut correctly, the light comes down and hits one side of the “V”, which acts like a tiny mirror (in fact all of the facets act as tiny mirrors), bounces across to the other side, and is then reflected back up through the table (top) of the stone.

Thats where the diamond gets its brightness. If one of those reflecting facets is not alligned correctly, then the stone will not reflect the light fully and you get dull and/or dead spots in the stone, or the whole stone may be dull.

The round brilliant cut stone has a distinct advantage in sparkle because no matter which way the stone is turned, you always have an opposing facet, ready to “send out the light”. The only other stone that has opposing facets is the square cushion cut, which is one of the main reasons that it is growing in popularity so quickly… its simply a VERY bright stone.  Marquises, pears, hearts as well as princess cuts have their own charms, but they are incapable of reflecting as much light as the opposing facet stones.

Redesign Engagement and Wedding Bands

True… women are sentimental. We love those tender feelings associated with our marriage jewelry. For years we’ve enjoyed seeing our engagement and wedding bands moving and flashing in front of us as we light candles, type or text, wipe tears, or stir the spaghetti. Even if, as often happens, that original jewelry lies quietly in our jewelry box, it has special meaning to us.

Still, after those years since this married life started, we might like a remake. Perhaps an update or even an upgrade… a renewal of those original pieces. We’d like to keep the sentiment but redesign to reflect our status… our maturity… our current lifestyle. We know who we are.

There’s an upsurge in this trend to remake. And what amazing new jewelry Davenport has been making from the diamonds, metals, memories, and inspiration of those original engagement, wedding, and anniversary bands.

Our customers have:

  • Decided to have only one band and consolidated their stones
  • Added colored diamonds, ruby, sapphire, or tsavorite, to give that burst of color
  • Bought a bigger diamond
  • Used the gold from the original pieces in the new jewelry (impractical to do with platinum)
  • Used the shank from an original engagement ring to make custom half-ring earrings
  • Placed the original engagement diamond in a unique spot on the side of the new ring
  • Or secretly hidden the original diamond on the inside of the new shank

Each customer brings unique ideas along with original jewelry and leaves with fascinating and beautiful new pieces.

Let the trend continue.
