Estimating the value of an 18-carat gold ring (also called 750/1000 gold) is not always simple, as several factors come into play. As specialists in precious metals for jewelry creation, we offer you a comprehensive guide to decipher the value of your precious jewel.
What is 18-Carat Gold (750/1000 Gold)?
Before getting to the heart of the matter, let's recall what 18-carat gold is. It is an alloy composed of 75% pure gold (24 carats) and 25% other metals (such as copper, silver, palladium) which give it its strength, durability, and color (yellow gold, white gold, rose gold). This fineness is often indicated by the "750" hallmark or an eagle's head (in France). 18-carat gold is the standard in high jewelry for its excellent balance between purity and resistance.
Key Factors That Determine the Value of Your 18-Carat Gold Ring
Several elements must be considered to estimate the price of an 18-carat gold ring:
1. The Weight of the Gold: The Basis of Value
-
The fundamental element is the amount of pure gold contained in the ring. The heavier your ring, the more gold it contains and the higher its intrinsic value will be.
-
How to calculate? For a rough estimate, you can weigh your ring (ideally without the stones, if possible, or by estimating their weight to deduct). Then multiply this weight by 0.75 (to get the weight of pure gold) and by the current price per gram of gold.
-
The price of gold: This price fluctuates daily according to financial markets. Check specialized websites to know the current price of 18-carat gold (or fine gold, then apply the 75% ratio).
2. The Presence and Quality of Precious Stones
If your 18-carat gold ring is set with stones, their value adds to that of the gold:
-
Diamonds: Their value is determined by the "4Cs": Carat (weight), Cut, Clarity, Color. A gemological certificate (GIA, HRD, IGI) certifies these characteristics and increases the value.
-
Other precious stones (Sapphires, Rubies, Emeralds): Their rarity, color, purity, cut, and origin greatly influence their price. Our white gold ring with diamond and sapphire cross is a fine example.
-
Semi-precious stones: Aquamarines, amethysts, citrines, etc., also have value, although generally less than precious stones.
3. Design, Craftsmanship, and Signature
-
Craftsmanship: A finely crafted ring, with a complex or unique design, will have added value compared to a simple setting. The jeweler's expertise is an important criterion. Think, for example, of a open 18-carat gold ring adorned with a Virgin, whose specific design and symbolism can add to its desirability, or a minimalist 18-carat gold chain ring with a diamond which, although discreet, represents precise design work. Every detail counts.
-
Brand or designer: A ring signed by a major jewelry house (Cartier, Van Cleef & Arpels, Boucheron, etc.) or a renowned designer will have a much higher value than an unsigned ring, even with equivalent gold weight and stones.
-
Era and style: Antique rings (Art Deco, Art Nouveau, etc.) can have a collector's value that exceeds the simple value of the materials.
4. Condition and Age
-
General condition: A ring in excellent condition, without deep scratches, deformations, or visible repairs, will be better valued.
-
Historical or sentimental value: Although difficult to quantify on the market, a particular story or illustrious provenance can add interest (but not always direct monetary value without tangible proof).
5. Hallmarks: Guarantee of Authenticity
-
Hallmarks (eagle's head for 18k gold in France, "750") certify the purity of the gold. A ring without a clear hallmark or with a doubtful hallmark will be more difficult to value and may require an appraisal.
Where and How to Have Your 18-Carat Gold Ring Appraised?
-
Professional jeweler: This is often the first contact. They can give you an estimate based on materials and the market.
-
Gemologist expert: Essential if your ring has significant precious stones, for a precise evaluation of them.
-
Gold buying counters: They will mainly base their offer on the weight of the gold and the current price. Beware, their offers are often lower than the full market value of a jewel (they generally do not value craftsmanship or small stones).
-
Auction houses: For exceptional, signed, or antique pieces.
Conclusion: A Multifactorial Value
As you can see, the value of an 18-carat gold ring is the result of a combination of many factors. The price per gram of 18k gold is a starting point, but the beauty of the design, the quality of the gems, and the fame of the creator can multiply this base value.
