How Much is a No Heat Loose?
Finding the Right loose-gemstones for You
Are you shopping for diamonds and other loose gemstones to create your own custom jewelry?
Why might you purchase a diamond or gemstone “loose” — that is, on its own, not mounted in a piece of jewelry? Perhaps you’re a connoisseur looking to acquire a unique investment. The scarcity of high-quality colored diamonds, for instance, especially pink diamonds, means that their value increases over time; the same is true of rare Kashmir sapphires and Burmese rubies. Far rarer than diamonds, Paraiba tourmaline, discovered only in the 1980s, is treasured as much for its extraordinary color as its scarcity, both of which contribute to its high value.
A more common scenario would be that you’re hoping to create a very special piece of custom jewelry, such as an engagement ring or a milestone-birthday present, and want to personally select the most beautiful, unusual, or ultra-rare stone you can find and afford. Doing so adds to the romance and substance of the gift and can be a part of the story told as the jewel is passed from generation to generation.
If this sounds like you, read on for tips on becoming one of the world’s savviest gem hunters.
Educate yourself: When buying any piece of gem-set fine jewelry, you should familiarize yourself with the factors that determine a stone’s price. This will enable you to streamline your search for the perfect gem and have intelligent, productive conversations with sellers.
There is a wealth of information online, such as our diamond-buying guide and this overview of colored gemstones for engagement rings. The buying guides of the Gemological Institute of America (GIA), searchable by stone type, are also a widely trusted source for consumers venturing into the world of diamonds and gems for the first time.
Vet your vendor: If you peruse 1stDibs with any regularity, you know there is no shortage of vendors who deal in top-quality loose gemstones. (Read about our vetted sellers.) Finding a trustworthy, established dealer may be as easy as getting a recommendation from friends or family. And, although it may sound obvious, it pays to Google your candidates — and consult customer reviews — before making contact.
Harakh Mehta, designer and founder of the Mumbai, India–based fine-jewelry brand Harakh, has an innate understanding of proper client relations, especially when the customer is in unfamiliar territory. “Start chatting with the dealer, get to know them better," he says. "It’s very important to establish a comfort level. We never push a sale, as we want it to be a carefully considered purchase. So, if the client is not in a rush, we do it over a few virtual meetings or phone calls.”
Request documentation: The best dealers go to great lengths to furnish clients with documents verifying the quality rating, natural origin and provenance of a stone — showing, for example, that loose emerald hails from the famous Muzo mine in Colombia — and disclosing any treatments applied to enhance its appearance. (And who doesn't love emerald jewelry? The most valuable emeralds are the ones that have a deep bluish-green to true green color and no visible inclusions.)
If no grading report is available for a stone you are interested in, the dealer should be able to provide an authenticity document, such as an appraisal or info sheet, that has been signed by an in-house gemologist or professional appraiser. Google those names, too, for extra peace of mind.
Ask for videos and visuals: When transacting with a gem dealer online, you should always request real-time videos and photographs, since professional photos of a stone, usually on a white background, have likely been retouched for optimal presentation.

- What is a no-heat sapphire?1 Answer1stDibs ExpertApril 5, 2022A no-heat sapphire is a sapphire gemstone in its natural state. It differs from sapphires that undergo heat treatment to enhance their surface. Generally, no-heat sapphires are smoother, while heated sapphires are harder and more lustrous. Shop a range of sapphire gemstone jewelry on 1stDibs.
- How loose should a bracelet be?1 Answer1stDibs ExpertMarch 13, 2024How loose a bracelet should be depends on what type it is. Typically, a bangle bracelet should be around 0.75 to 1.25 inches larger than your wrist circumference for a looser fit. On the other hand, a cuff bracelet should provide a snug fit to keep it in place throughout the day. Look for cuffs that are about the same size as your wrist circumference for the best results. When shopping for tennis, leather, beaded and other bracelets secured by clasps, aim for a slightly loose fit by selecting a piece that is about 0.5 to 1 inch longer than your wrist circumference. Explore a wide variety of bracelets on 1stDibs.
- Do sapphires conduct heat?1 Answer1stDibs ExpertMarch 22, 2022Yes, sapphires conduct heat. In fact, a real one won't melt until it reaches a temperature of 3,711 degrees F. As a result, one way that experts test sapphires to determine if they are real is to heat them to high temperatures. Find a collection of sapphire gemstone jewelry on 1stDibs.
- Are Burmese rubies heat treated?1 Answer1stDibs ExpertApril 5, 2022Yes, Burmese rubies are heat treated. Most rubies are heat treated directly at the mines because the treatment enhances the value and quality of the ruby. Shop a wide collection of Burmese ruby pieces as well as other fine jewelry on 1stDibs.
- 1stDibs ExpertApril 5, 2022Whether or not terracotta pots can withstand heat depends on how well they are made and cared for. A finely crafted pot can usually hold up in the face of high temperatures. If you intend to cook with one, season it with cooking oil to increase its durability. Shop a collection of terracotta pots on 1stDibs.
- 1stDibs ExpertApril 5, 2022No, not all fireplaces need a heat shield. However, a heat shield can enhance the visual appearance of the space while also protecting the room. Carefully measure your fireplace to ensure the best fit. Shop a wide range of heat shields and fireplace inserts on 1stDibs.
- Roman Malakov DiamondsMarch 22, 2021A heated ruby is a ruby wherein 1600 - 1700 degrees centigrade of heat is applied to the stone to improve it's color, luster, and/or clarity. This is a common method for most rubies is not a bad at all. What makes unheated rubies valuable is their rarity. To find a beautiful ruby that does not need heat to improve it's beauty is very rare and highly unlikely.
- How do I sell a loose ruby?1 Answer1stDibs ExpertApril 5, 2022To sell a loose ruby, you have a few options. You can have the stone evaluated by a licensed appraiser and then find a buyer in your local area. Another option is to work with a jeweler or auction house. Alternatively, you can list the gem on a reputable online platform. Shop a variety of loose gems on 1stDibs.
- Which mugs hold heat best?1 Answer1stDibs ExpertMarch 31, 2023There is no single mug type or brand of mugs that holds heat best. While materials do play a role in determining how well mugs hold hot beverages at temperature, other factors like whether the metal is insulated, how well the mug is crafted and how tightly the lid fits also have an impact. Find an assortment of mugs on 1stDibs.
- 1stDibs ExpertJanuary 23, 2024Generally, a cuff bracelet should be tight rather than loose. Since a cuff bracelet doesn't have a clasp or closure, it can slip off or shift if it fits too loosely. At the same time, an overly tight cuff can be uncomfortable. Measuring your wrist and comparing the size to the inner circumference of cuffs can help you select a piece that will fit you securely and comfortably. Shop a wide variety of cuff bracelets on 1stDibs.
- 1stDibs ExpertDecember 12, 2023Whether Cartier will set a loose diamond depends on the circumstances. If you purchased a piece of Cartier diamond jewelry and the stone has come loose, contact customer service for assistance with repairs. Cartier will usually not place a loose diamond that you purchased elsewhere in one of their settings. Find a wide range of Cartier diamond jewelry on 1stDibs.
