Gemstones in Our Candles
What type of gemstones does Precious Gem use in their candles?
At Precious Gem Candles, we purchase natural faceted gemstones that are "Jewelry Store" quality. Our gemstones have been independently graded, meaning they are graded before we receive them. We are proud that our gemstones come from a reputable gemstone and diamond dealer, meeting the high demand and standards of custom jewelers. 99% of our gemstones are AAA grade with an occasional Super Fine stone, AA stone, or lab-created stone.
Our gemstone supplier deals in diamonds, pearls, precious and semi-precious stones. The information provided for each stone we purchase helps us know that our stones are of the highest quality. We know the origin, luster quality, treatment, grade and carat weight of each gemstone. Our faceted gemstones are calibrated so that we also know the size of the gemstone is a standard size for easy setting and mounting.
How we value our gemstones:
One of the ways to find out the value of your gemstone is to take it to a jeweler and ask them what they would sell a stone like yours for. If they are willing to take the time to weigh the stone and exam it under a 10x magnifier to evaluate the inclusions, cut and symmetry, they can give you an idea of it’s value.
Another method some use is an online valuation tool called GemVal. If you want to check the value of semi-precious gemstones, it is a free online service. To check the value of precious stones, you must have a paid subscription. However, there are some potential issues using GemVal. The site doesn't take into consideration the origin of the gemstone which is important to know when value and authenticity are concerned. Some of GemVal's reference graphics for choosing a matching color to your stone are off so it makes it hard to choose the appropriate color match. We have also found that often times GemVal over values a gemstone. You can try their free online service at gemval.com, but be aware that you might get a result that is higher than the real value of your gemstone.
When you purchase a Precious Gem Candle, we provide a method to find out the market value of your gemstone which is provided to us by our jewelry supplier. Because our supplier is in the jewelry store market, they stay current on the market value and wholesale values of gemstones (which can fluctuate quickly). You’ll find our market value to be on the conservative side of the value, but we think it’s better if you later find out your stone is worth more than to find out it’s actually less than one of the other valuation methods.
What makes one gemstone of the same type more valuable than another?
The four “C’s” were introduced to help consumers understand the factors used in grading diamonds. With a little modification, these are also helpful in determining the quality of a gemstone, but in a different order.
First, the purity and beauty of the color is the primary determinant in quality of a gemstone. Physical characteristics that make a colored stone valuable are color, clarity to a lesser extent (emeralds will always have a number of inclusions), cut unusual optical phenomena within the stone such as color zoning, and asteria (star effects).
With the use of 10x magnification, stones can be more accurately graded for clarity, although part of the grading process still involves use of the naked eye (assuming 20/20 vision). Hence, the term “eye clean.”
