Sell or Pawn Your Gold at All Island Jewelry & Loan

We Buy Gold and Silver Platinum

All Island Jewelry & Loan deals in all types of gold and silver platinum. All gold and silver purchases and pawn loans are based on the current spot price for gold and silver.

GOLD is usually stamped 10K, 14K, 18K. Gold is bought by the pennyweight (dwt). There are 18.2 dwt to the avoir oz. or 20 to the troy oz. Dental gold must be yellow and is usually around 16k. Items stamped 1/20 12k – H.G.E. are gold plated and worth very little.  Once the pieces are weighed they are also tested for purity. We test all gold, marked and unmarked.  If there are diamonds or other precious stones in the item brought in, we will add their value to the weight of the gold.

To determine the value of your pieces there are a few considerations: Is the piece signed or from a designer name? If the answer is YES, don’t let anyone pay you just on the gold price. Specialty items carry specialty premiums a distinction that few other companies will make when making you an offer.

There are three numbers which are used to calculate the value of your gold:

1.   Weight: What is the weight of your item?
2.   Purity: Is the piece 10kt, 14kt, 16kt, 18kt, 22kt or 24kt?
3.   Gold Price: What is today’s gold price?


All Island Jewelry & Loan also buys diamonds, silver, coins and currency, watches, jewelry, and other collectibles. Whether you are looking to sell your valuables or to obtain a pawn loan, we pay top dollar and pride ourselves on a solid reputation of integrity. Just bring your items to our store in Centereach, Long Island, New York and our experienced staff will give you an estimate of the value of your unwanted gold or jewelry.

Here is a quick summary of our most popular selling and pawn loan categories:


Diamonds can be very valuable depending on some characteristics the diamonds may have. The shape, cut, color, clarity, and carat weight all play an important role in the overall value of your diamond. Learn more.


Items must be stamped “Sterling” .925 – .900 – .800. Many items stamped Sterling are weighted with plaster (i.e. candlesticks) and must be broken to get the true weight. Knives which have sterling handles are figured at 1/3 – 1/2 oz. each.

Coins and Currency

All Island Jewelry & Loan deals in all types of U.S. and Foreign Coins. U.S. 90% silver coins are dimes, quarters, or halves dated 1964 or older. U.S. 40% clad coins are halves only dated 1965-1969. War Nickels are dated 1942 – 1945 with large mint marks only. Silver dollars were minted up to 1935. We buy all early U.S. & foreign coins and paper monies, but coins that are damaged in any way are almost unsaleable, but may have scrap value. The better condition the higher the price. We pay top dollar on all gold and silver coins.


Many common gold watches made in the last 20 to 30 years are probably worth their weight in gold only, but All Island Jewelry & Loan will examine the watch to determine if it has any value above melt. Hunting case watches (flip Covers) that are working or repairable are valuable. Repeater watches which chime the time are very valuable – often worth over $1,000. Old silver watches are also worth a premium. Particularly valuable watches are Rolex; Cartier; Tiffany; Omega; Patek; Phillipe; Piaget.
