Precious stone quality

Precious stone quality

All of the diamonds and gemstones we offer at DVM Jewellery are acquired at the diamond exchange in Israel, London or Antwerp. Each diamond or gemstone is individually chosen by our jeweller and comes with a GIA or IGL certificate of authenticity.

Your preferences of the diamond quality can be individually chosen for each jewellery piece you create with us.

What affects the diamond quality?

Diamonds all over the world are graded according to the “4Cs” rule: cut, color, clarity and carat weight. The size does not affect the quality of the stone, because a small diamond can be as beautiful and well finished as a larger diamond. The quality of a diamond largely depends on the raw material, but the final look of the diamond is born in the skillful hands of a jeweler.

Most diamonds are round, especially with an excellent or very good cut. Ideally, the surface will be so flat that imperfections will not be visible to a naked eye.

Fancy diamonds do not receive grades from GIA due to the wide variety of shapes and cutting styles, each with its own length-to-width ratio and set of standards

Remember, your personal preference are important. However, these 4 points should be paid attention to before choosing a dream stone:

1. The ratio of length to width (L to W) It is important to consider because gemstones that are too narrow are prone to chipping. Most people find certain ratios more attractive than others. Thus, emerald and rectangular cuts are popular with an L-W ratio between 1.50: 1 and 1.75: 1

2.Symmetry of lines. For heart and pear shaped diamonds, the outline of the diamond should be the same on both sides of the conditional line in the middle. For oval, square, rectangular and marquise shaped diamonds, the outline of the diamond should be the same on each side vertically and horizontally. Symmetry makes the diamond crisp and neat and helps maximize the brilliance of the diamond

3. Smooth curves. Curved shapes such as hearts, pears, and ovals should have full, rounded “petals” or “shoulders”

4. A definite form. The heart, for example, should have a clear cleft and a clear opposite point, and not look like a flat pear. The attractiveness of the diamond shape depends on the ratio and your preference
