Gemstones can form naturally within the Earth or be grown in controlled laboratory environments. Understanding their origin is an important part of appreciating what makes each stone unique.

Natural Gemstones

Natural gemstones are created through geological processes over time. Their color, internal features, and character reflect the conditions in which they formed.

Laboratory-Grown Colored Gemstones

Laboratory-grown colored gemstones are created through controlled growth processes. When properly identified as laboratory-grown counterparts, stones such as ruby, sapphire, and emerald have essentially the same chemical composition and crystal structure as their natural equivalents. Their primary distinction is origin.

Like natural colored gemstones, laboratory-grown stones vary in color, transparency, cut, and overall appearance. Each deserves to be considered on its own visual qualities.

Laboratory-Grown Diamonds

Laboratory-grown diamonds are real diamonds, with essentially the same chemical composition and crystal structure as natural diamonds. They are grown using advanced processes, principally CVD (Chemical Vapor Deposition) or HPHT (High Pressure High Temperature), rather than forming through natural geological conditions.

Laboratory-grown diamonds are not all identical in quality. Color, clarity, cut, and light performance can differ from stone to stone, making thoughtful selection just as important.

Color is often the first quality we notice in a gemstone. Its hue, depth, and saturation influence how vivid, soft, or subtle a stone appears. The most desirable color is not always the most expensive one; personal preference matters.

Clarity describes a gemstone's internal and external characteristics. Some inclusions are visible only under magnification, while others can affect transparency or the stone's appearance. Different gemstone varieties should not be judged by a single clarity standard.

Whether natural or laboratory-grown, a gemstone is best appreciated as a whole: its color, clarity, and character together.

Cut is more than a gemstone's outline. Its proportions, facets, symmetry, and polish influence how light moves through the stone and returns to the eye.

Well-considered cutting can bring out brightness, sparkle, and color. Excessive light leakage, overly dark areas, or a pronounced window can reduce a gemstone's visual appeal. Colored gemstones and diamonds may call for different cutting priorities.

Carat measures weight, not visible size. Two gemstones with the same carat weight may look different because of their shape, depth, and proportions. Measurements in millimeters can be just as useful when comparing stones.

Begin with what you see. Consider a gemstone's color, transparency, balance, and light performance in ordinary viewing conditions. Then look at its measurements, grading information, and other technical details. Finally, consider its price in the context of its overall qualities.

Think about how the jewelry will be worn. Hardness, resistance to chipping, setting design, and care requirements all matter, especially for pieces intended for everyday use.

The right gemstone is not necessarily the largest or the one with the highest grade. It is the one whose beauty, character, and practical qualities feel right to you.

Independent gemological reports can provide useful information about a gemstone's identity and selected characteristics. Depending on the report, these may include weight, measurements, color, clarity, origin, or detected treatments.

Diamond reports may also include cut-related grades. A report is a valuable reference, but it is not necessarily an appraisal or a statement of market value, and it cannot replace seeing how a stone looks.

At JAVO, we identify gemstones as natural or laboratory-grown and describe relevant material details. Independent reports are provided or linked where available. We believe transparency and individual beauty belong together.
