Diamonds found how to test at home the

[jbbj]

I was metal detecting old house I bought. Found some diamonds in one hole. Trying to see if there really real or not. And if real what’s the value if any?

You can get an electronic diamond tester off Ebay or Amazon for less than $25 shipped. They really work.

[jbbj]

Found out were fake lol. I’m not that lucky lol

 

[jbbj]

Thank you everyone

 

[bradyboy]

never say never
ask for a second opinion
also, have them checked for to see if they are glass or actual stones
think you gave up to fast on your find
IMO

[bradyboy]

am I wrong by saying all the stones are mounted and found in the same hole?

They look like post depression era jewelry.

Easiest first indicator. They don’t use crappy mountings for expensive stones. No little shoddy tabs holding them in.

Your gemstone finds look to be 'paste glass'.
Date wise, based on the setting... 1910 - 30 .

Paste Jewelry - History

"Paste, heavy, very transparent flint glass that simulates the fire and brilliance of gemstones because it has relatively high indices of refraction and strong dispersion (separation of white light into its component colours). From a very early period the imitation of gems was attempted. The Romans were very skillful in the production of coloured-glass pastes, which copied especially emerald and lapis lazuli. With an increasing demand for jewelry, the number of imitations steadily increased. In 1758 the Viennese goldsmith Joseph Strasser succeeded in inventing a colourless glass paste that could be cut and that superficially approached the sparkle of genuine diamond; the products of this paste are called strass stones.Prior to 1940, most imitation gems were made from glass with a high lead content. Such glasses were called paste because the components of the mixture were mixed wet to ensure a thorough and even distribution.

Pastes are softer than ordinary or crown glass but have a higher index of refraction and dispersion that give them great brilliancy and fire. The cheaper paste imitations are pressed or molded, but, on the better-quality stones, the facets are cut and polished. Molded-glass imitations can be identified with a hand lens, because the edges between the facets are rounded whereas cut glass has sharp edges. Cut paste stones may be distinguished from real ones in several ways: paste has air bubbles, natural stones do not; paste is a poor conductor of heat, and so paste stones feel warm to the touch; and paste, like all glass, has an easy conchoidal fracture, yielding brilliant curved surfaces particularly on the girdle (the widest part) of mounted stones near the mounting prongs. Other differentiation methods involve hardness, paste is softer than real stones and will not scratch ordinary glass."

With a loupe (jewelers type magnifier) you should be able to see black specks in it, since they originate from coal (that’s my understanding at least). If totally clear, totally fake. I still don’t throw them out till I check with a professional. Some I keep anyways because I’m convinced I saw a tiny black spot

 

[jbbj]

I was able to break them with pliers

I also look for scratches on them and the cut, and settings
