Characteristics of gemstones : comparison between white topaz and white CZ

Natural stones and synthetic stones

Fine and precious stones differ from synthetic stones in many ways. We generally look for perfection in synthetic stones. Being man-made, they can be cut, to achieve the perfect shape, the perfect color without any flaw. They can be produced in many colors, in many different shapes and in large quantities.

Nature’s work makes each rough unique, rare and valuable. This particularity implies the presence of inclusions, visible especially on large diameters of stones. 

To go further, let’s compare white cubic zirconia with white topaz. Even if these two stones are similar in appearance, they have distinctive features that set them apart.

Synthetic Stone: Cubic Zirconia

Cubic zirconia is mainly known and appreciated for its brilliance and transparency which makes it very close to that of diamond. The refractive index of CZ is 2.16 when that of diamond is 2.42. This brilliance is accentuated by the choice of the rough and of technical productions. Dalloz remains expert and leader in this field.

We control the manufacturing process from A to Z, since the creation of the rough to the final appearance of the stone. The resulting consistency allows us to obtain finished products of a high quality, close to perfection.

Fine Stone: White Topaz

White topaz is the most common color of topaz. The rough, unworked, is different each time. It contains inclusions visible or not to the naked eye. These inclusions are a sign of nature’s work and help differentiate a natural stone from a synthetic or imitation stone. This implies a level of brilliance and transparency that varies from one rough to another.

Depending on the rough, the lapidary decides how many facets he will be able to cut on stones, and whether he should cut them by hand or by machine. The amount of facets depends on the raw material and is variable depending on the craftsman.

Quality control

Our quality experts check all types of stones, whether they are synthetic or fine, on aesthetic and geometric criteria. Thus, analyses are carried out on white CZ and white topaz, with very distinct references. Inclusions, representing the soul of the natural stone, are forbidden for white CZ, whereas they are appreciated for white topaz, reflecting its value.
