It's true that raw diamonds found in nature don't typically have the sparkling and brilliant appearance we associate with cut and polished gemstones. Ancient humans likely didn't initially use Raw Diamonds Jewelry in their natural state. Instead, the use of diamonds for adornment evolved over time due to a combination of factors:

1. Rarity: Diamonds are among the rarest gemstones on Earth, and their scarcity would have made them inherently valuable and desirable to ancient societies. This rarity alone could have made them appealing as adornments for those in positions of power and wealth.
2. Hardness: Diamonds are the hardest known natural material. Ancient people may have discovered that diamonds could be used to cut, engrave, or polish other materials, which would have made them valuable tools. This utilitarian use could have contributed to their status as symbols of wealth and power.
3. Symbolism: In many ancient cultures, certain stones and minerals were associated with religious or spiritual significance. Diamonds may have been seen as symbols of purity, strength, or protection, leading to their use in amulets, talismans, and other forms of jewelry.
4. Evolution of Cutting and Polishing Techniques: The transformation of raw diamonds into the brilliant gemstones we recognize today is a relatively recent development. Ancient civilizations gradually improved their techniques for cutting and polishing diamonds, unlocking their hidden beauty. The art of diamond cutting and faceting has a long history, dating back over 2,000 years, and it was during this time that diamonds began to be used in more elaborate jewelry designs.
5. Trade Routes: As ancient trade routes expanded, diamonds from regions where they were naturally occurring (such as India and later Africa) were traded to other parts of the world. This increased availability allowed more people to become familiar with diamonds and their potential as adornments.

In summary, while raw diamonds may not have appeared beautiful in their natural state, various factors such as rarity, hardness, symbolism, evolving cutting techniques, and trade contributed to the gradual adoption of diamonds as jewelry and symbols of wealth and status among ancient cultures. Over time, humans learned to appreciate and enhance the natural beauty of diamonds, which ultimately led to their prominent place in the world of jewelry and luxury.
