A gemstone, also referred to as jewel, semi-precious stone, or gem, is a piece of mineral crystal that can be cut and polished to be used for adornment. Certain rocks, such as lapis lazuli and opals or other organic minerals like amber and pearl, are used as adornments and jewelry and, can therefore be considered gemstones. Many gemstones are hard stones, but some soft minerals are also valued for their aesthetic properties. Gemstones have been used to adorn manuscripts, jewelry, sculpture, and various types of tools and utensils.

I am so happy to have found Mearto. Their team of seasoned professionals provide a wealth of knowledge in tandem with excellent customer care. They provided an expert valuation and advised me sell a painting that I purchased for just $10 at an estate sale for nearly $1,000 on eBay. I have used them on several occasions and have been extremely pleased every time.
Mearto provides exceptional service at an exceptional price!
I used the Mearto authentication service to develop a history of a family owned piece with little to no provenance, except being owned by my family for 65 years. They came back with a 20 page extensive report and included a full page bibliography for reference. The “Stylistic Observations” section of the report was most enlightening comparing my piece to the original, which was on public display in the 1940’s.
I’m very happy with the results!
Very polite and professional services that they provide, my appraisal involved looking into an oil painting by an artist whose work is over 400 years old. Not only did they write about the artist but also where he was from and where he was born and most importantly the value, I'm impressed. (worth every penny).
I will always use Mearto for future appraisals.
The authentication report we received from Mearto was very well researched and written, as well as detailed and comprehensive. From an examination of the artist's signature to a discussion of the figural representations in the work, Mearto's art specialists took the time to explain in non-technical terms their findings. Professional, responsive, and kind are just a few words to describe their communication throughout the process-- definitely money well spent!
We needed a watch appraised and I found this website via Google. Having never doing this before, I was hesitant to submit a payment before receiving any information, I'm glad I did. David was very helpful and patient addressing my questions, and explaining the process. He was very thorough and knowledgeable. Should I have another opportunity, I would not hesitate to contact Mearto again.
The “cut” of a stone is often one of the most important factors in determining the value of a stone. The “cut” of a stone does not refer to the shape, but rather the proportion, symmetry, and polish. These factors determine how light intersects and is reflected from the stone; the quality of “sparkle” so to speak. Shaping a stone to maximize these factors is labor intensive and requires a skilled artisan. This labor is therefore factored into the price of the stone.
Of course, rarity plays an important role in the value of gemstones. The distinction between precious and semi-precious stones is a retired distinction in modern gemology, though diamonds, rubies, sapphires, and emeralds still have a reputation that exceeds those of other gemstones. Gemstones have no universally accepted grading system (unlike diamonds). Physical characteristics such as color and clarity dictate the value of gemstones. Blue and pink diamonds are often considered gemstones and can be extremely valuable. “The Pink Star” diamond was sold at Sotheby’s auction in Hong Kong in 2017 for a record-breaking $71.2 million; $1.19 million per carat. “The Oppenheimer Blue” diamond sold for a final price of $57.5 million at Christie’s in 2016 with the most valuable price per carat at $3.93 million.

Synthetic gemstones are chemically and physically identical to natural gemstones, but are created in laboratory settings. Imitation or simulated gemstones are chemically different, but visually similar to natural gemstones. Examples of simulated or imitation stones include cubic zirconia, which look similar to a true gem, but does not possess the same chemical or physical properties of a natural stone. Cultured, synthetic, or "lab-created" gemstones are not imitations: the bulk materials are chemically the same. Whether or not a gemstone is natural stone or synthetic, the chemical, physical, and optical characteristics are the same. Often synthetic gemstones are brighter in color and clarity; impurities in natural gemstones are not present in synthetic stones and are created at a cost significantly less than natural gemstones.
