Old diamonds can be worth more than new ones, especially rare, high-quality antique cuts (like Old Mine or European cuts) due to their finite supply, unique historical craftsmanship, and increasing demand, but this isn't always true; value depends heavily on the stone's individual characteristics (4Cs), market trends, and perceived historical or aesthetic appeal, with newer, perfectly graded stones also commanding high prices, so it's about character and rarity versus modern perfection.
As diamonds age from 100 years to 120 years old and we move further away from the 20th century, these old cuts will not only become more scarce but also more valuable. As an example, jewelry from the 17th century and older is extremely valuable and rare.
Ten years ago, in 2003, a 2.00-carat Fancy Intense Yellow diamond with a VS+ clarity grade cost $5,000 per carat. Today, that same stones goes for $13,500 per carat.
The resale value of a 1 carat diamond is usually between 20% and 60% of its original retail price. For instance: A $1,250 diamond would sell for $1,000 today but resell for ~$650 after a 35% discount. A quality-graded 1 carat diamond would sell for $1,036–$5,946 based on quality and sales medium.
Natural Diamond Price Trends
2015-2020: Prices remained stable with moderate increases. 2020-2023: Prices surged due to supply shortages and inflation. 2024-2025: Prices have softened as demand for lab-grown diamonds increased.
A diamond appropriate for 75% of a $20k engagement budget could range from 1 to 2.50 carats, or even higher, depending on the shape, and how it's graded in other areas. It may even be able to get you a diamond 3 carat or larger stone if you opt for a lab-grown diamond instead.
And whilst selling gives you the entire cash value of an item, pawning diamonds and jewelry will only provide you with a fraction of its resell value. You can sell your items to a pawnbroker but they are not diamond specialists. As such, they do not have the expertise and knowledge to offer the best prices.
For around $5,000, you can typically find a natural diamond ranging from 0.5 to 1.5 carats, depending heavily on quality (the 4Cs), cut, setting cost, and if it's lab-grown, but a good quality 1-carat diamond often starts near this price point. A $5,000 budget could get you a significant stone like a 1-carat diamond or even larger lab-grown options, but quality factors (color, clarity) will significantly impact size and price.
Diamonds typically lose between 25 and 50 per cent of their actual worth upon resale due to market fluctuations, the markup on your ring, and the decline in diamond prices. A portion is also taken out for insurance.
The Aquamarine name comes from the Latin word for seawater and is said to calm waves and keep sailors safe at sea. It is sometimes referred to as a poor man's diamond because of the pale color.
From 1979 to 1980, a one-carat D-flawless stone rose in price from $10,000 to $65,000. (That's the time gold reached a high of $850 a troy ounce; gold has also plummeted nearly 50 percent since then.) But the price of diamond jewelry has gone up much less.
Numerous factors influence a diamond's resale value, including its quality, market demand, and how and where it was originally purchased. Unlike gold or other commodities, diamonds do not have a standard market price per gram, making it crucial to understand the nuances of diamond ring resale value.
Jewelry professionals can identify the period of a diamond by examining the shape and facets of the stone. Diamond cuts have evolved from early old mine to today's brilliant-cut diamonds. Trained professionals can analyze the diamond to determine its approximate age.
Taylor Swift's engagement ring features a large, antique Old Mine Brilliant Cut diamond, which is a vintage style with rounded corners, a high crown, and large facets, giving it a soft, candlelit sparkle rather than sharp modern flashes, often described as an elongated cushion shape with a small, open culet. This historical cut, popular in the 18th and 19th centuries, was chosen for its romantic, nostalgic character, perfectly suiting the ring's yellow gold setting with hand-engraved details.
Size is subjective and varies depending on personal preference and budget (and even things like finger size, if you're looking at engagement rings!). However, diamonds of one carat and above are typically considered large.
The 2-1-1 jewelry rule is a styling guideline for balanced accessories, generally meaning two pieces on the hands/wrists, one piece on the neck, and one piece on the ears, or variations focusing on visual weight distribution like two subtle pieces, one medium, and one statement for a cohesive look without clutter. It helps create intentional, effortless style by balancing different accessory types and placement, preventing the "Christmas Tree effect" (too much in one spot).
To sell jewelry without getting ripped off, research its value first, get multiple appraisals from reputable jewelers (not just pawn shops), use online marketplaces like eBay for broader reach (after checking sold listings), and consider consignment or auction houses for high-value pieces, always verifying buyer credentials and understanding the process.
One of the main reasons for this concern is that diamond mines are not infinite resources – eventually, they will run out. As Gemological Institute of America research scientist Evan Smith says, “For every diamond you take out of the ground, there's one fewer to be found.”
Michelle Obama has two engagement rings: her original was a 1-carat round diamond, but in 2017, she received an upgrade to a larger, estimated 2.5 to 3-carat princess or cushion-cut diamond in a pave setting, with reports suggesting the new one is worth significantly more.
Engagement rings typically sell second-hand for 30%-50% of the original retail price. To get the best price for your diamond ring, it pays to sell to the experts.
Among the Kardashian sisters, the most expensive wedding ring belongs to Kim Kardashian, whose husband Kanye West reportedly spent around $4.5 million on a 20-carat emerald-cut diamond ring for her.
