What is a diamond?
Diamond is the hardest mineral on Earth. Its hardness is due to the distribution and composition of the only atoms that compose it, the carbon atoms.
The name of diamond comes from the Greek "adamus", which means "to take" or "subdue", referring to its great hardness.
Most of the diamonds come from two types of volcanic rocks: lamproite and kimberlite.
The four best-known quality criteria for valuing a diamond are the popularly called “4C”, acronyms in English for Carat (Weight), Color (Color), Clarity (Purity) and Cut (Size or Cut).
-
Cut: The cut is the element that reveals the brilliance of the diamond. The cut or carving refers to the proportions of the stone. A diamond sparkles and shines based on its cut, and this is determined by how the facets interact with light.
-
Color: Color is one of the most important characteristics of a diamond: the whiter (transparent), the more beautiful, rare and valuable. To determine the clarity or transparency of a diamond, there is a color scale established by the GIA Gemological Institute of America) that divides the color grades from D to Z, with D being the best quality.
-
Clarity: Clarity refers to the minute natural blemishes present in all diamonds. These imperfections will cause the diamond to increase or decrease its value.
-
Weight: The “Carat” (weight) is the unit of measurement for diamonds. The weight of a diamond is measured in carats, abbreviated as ct. The metric carat corresponds to 0.20 gr
What is aquamarine?
Aquamarine is a Beryl, from the ancient Greek "beryllos": green-blue gem, beryl is known in the world of gemology as the "mother of gems" for its variety in precious precious stones.
Aquamarine means “water of the sea” and derives from the Latin words: “aqua” (water) and “marinus” (belonging to the sea).
It is a transparent and eye-clean gemstone (it does not have inclusions visible to the naked eye at a distance of 15 cm). In the case of Aquamarine, said transparency is maintained even when observed under a magnifying glass.
What is the Sapphire?
The name of the Sapphire derives from the Latin "sappheiros" which means blue. Sapphire is classified as a precious or fundamental gem along with ruby, emerald, and diamond.
Sapphires can be found in various colors such as orange, green, or yellow, but the most valuable are deep blue or gentian blue. Some cabochon cut sapphires have the optical effect of a star inside.
