Darkfield Stereo Jewelry

To buy small loose diamonds is probably the best way to buy diamonds. When people are shopping for small loose diamonds at a jewelry store, it is always advisable to ask the dealer for a 10X eye loupe with which it is possible to closely examine the diamond. And, if people intend to buy small loose diamonds, it would be better if they bought a 10X eye loupe directly from a jewelry house. The best way to verify a diamond for clarity is with a stereoscopic binocular microscope, which comes with dark field lighting.

The most common shapes for small loose diamonds are baguette, emerald, heart, marquise, oval, radiant, round, brilliant, and princess. Manufactures or artisans who make diamond jewelry generally buy small diamonds. They normally buy this diamond in bulk, and make different types of diamond jewelry and some might also use it to make diamond watches or embellish shoes and purses. When loose diamonds are set in any article it becomes an exclusive piece and is always expensive.

There is a search engine designed online specifically for loose diamonds, where people could search by shape, weight, cut, color, clarity and price. There are Retailers who get the lists of available diamonds from wholesalers around the country. Those wholesalers give the retailers a cost price and the retailers decide how high to mark up each diamond. The difference in price between retailers could be around $10,000 for a large diamond. This is basically how the search engine for loose diamonds work

These retailers will then post that diamond to their online inventory, but the price people pay will be different at each site. When they decide to purchase diamonds, the retailer notifies the wholesaler and that diamond is removed from inventory and is no longer available to any other online retailer.

Loose Diamonds provides detailed information on Loose Diamonds, Wholesale Loose Diamonds, Certified Loose Diamonds, Loose Diamonds For Sale and more. Loose Diamonds is affiliated with Diamond Engagement Rings.
