Diamonds form roughly 100 miles below the Earth’s surface under extreme pressure and heat, over a span of one to three billion years, and reach the surface only through rare volcanic eruptions. That is why a natural diamond is scarce and why it holds value across generations. It is also why a diamond you no longer wear is worth a serious look. Here are the main reasons people in New York sell their diamonds, and what to know before you do.
1. Fast Money When You Need It
A diamond is one of the most concentrated stores of value you can own. A stone the size of a pea can be worth thousands of dollars, and it can be evaluated and paid for in a single visit. When a medical bill, a legal fee, a move or an emergency arrives without warning, a diamond is a resource you can draw on the same day. If you would rather not sell permanently, a collateral loan lets you borrow against the diamond and reclaim it later.
2. Letting Go of Painful Memories
Jewelry holds meaning, and not all of it is good. A ring from a marriage that ended, a pendant from a relationship you have moved on from, or a piece connected to a loss can weigh on you every time you see it. Selling is a clean way to close that chapter. Many customers tell us the money mattered less than the relief.
3. It Is Sitting Unused
Most diamond jewelry spends its life in a box. Pieces are worn once or twice a year, if at all. An unworn diamond earns nothing, costs money to insure and is at risk of loss or theft. Turning it into cash lets you put that value into something you will actually use, whether that is a piece you choose for yourself, an investment, or an experience.
4. Inherited Stones That Do Not Fit Your Life
Estate diamonds are often in settings from another era or another taste. Rather than pay to reset a stone you feel obligated to keep, many heirs choose to sell and share the proceeds, or to sell some pieces and keep the ones with the most meaning. A professional appraisal gives everyone an honest starting point.
5. The Market Is Strong
Large, high-color natural diamonds, fancy colored diamonds and signed pieces from Tiffany & Co., Cartier and Harry Winston have held their value well even as lab-grown diamonds have pressured the market for small commercial stones. If you own a natural diamond of one carat or more, or a signed piece, the current market rewards sellers who go to a specialist buyer.
What Your Diamond Is Worth
Value is based on the 4Cs (carat weight, color, clarity and cut), the shape, whether the stone is certified by GIA or AGS, and the mounting. A round brilliant with a GIA report is the easiest to price. Fancy shapes, older cuts and uncertified stones are graded in-house by our gemologists. Signed mountings and matched side stones add to the total.
How to Sell Diamonds Safely
- Bring every document you have: GIA or AGS reports, appraisals, receipts, original boxes. If you have none, we grade the stone in front of you.
- Do not remove the diamond from its setting yourself.
- Choose a buyer with gemologists on staff, not a gold buyer who weighs the whole piece.
- Get the number first. A real evaluation is free and carries no obligation.
- Bring a government-issued photo ID, which New York State requires.
