| Criteria | Description |
| Color | The hue, tone, and color saturation of the gem. For colored stones, this is usually the single most important factor. |
| Clarity | The absence of internal flaws (inclusions) or surface blemishes. Clearer stones reflect light better and are more valuable. |
| Cut | How skillfully the stone has been shaped and faceted to maximize its sparkle and brilliance. |
| Carat | The physical weight of the gemstone. One carat is equal to 0.2 grams. |
Yes! While stones like quartz and sapphires are found on multiple continents, some are location-specific:
The standard “Round Brilliant Cut” is the most popular style for diamonds and many other gems because it has been mathematically designed to reflect the maximum amount of light back to the viewer’s eye. It creates the highest level of brilliance and sparkle compared to other shapes. Would you like to know anything else, perhaps…
Many people confuse these terms, but they are very different: Hardness: Measures a stone’s resistance to scratching (using the Mohs scale). Toughness: Measures a stone’s resistance to breaking, chipping, or fracturing from a hard blow. Example: A Diamond is the hardest (10), meaning it won’t scratch easily, but it is not the “toughest.” A hard…
Scientifically, there is no difference! Both Sapphire and Ruby are exact same mineral: Corundum. The only difference is the trace elements present during their formation. If corundum has traces of chromium, it turns red and is called a Ruby. If it has traces of iron and titanium, it turns blue (or yellow, pink, green) and…
A doublet or triplet is a stone that is composed of two or more pieces. Often, a thin slice of a high-quality, expensive, or naturally colored stone is glued to a base of a cheaper material (like black glass or plastic) to make it look larger or more expensive. Always check the sides of a…
Geuda is a semi-transparent, pale, and cloudy form of corundum found abundantly in Sri Lanka. For centuries, it was considered low-value, useless gravel. However, in the 1970s, it was discovered that applying specific high-heat treatments to Geuda transforms these dull stones into brilliant, deep Blue Sapphires. This groundbreaking discovery revolutionized the Sri Lankan and global…
