What does 585 gold assay mean > How much pure gold is in 585 assay

A com­pro­mise between a high con­tent of pre­cious met­al and good phys­i­cal char­ac­ter­is­tics is 585 gold, which is a guar­an­tee of the dura­bil­i­ty of jew­el­ry and its high val­ue.

What does gold grade 585 mean?

Gold is char­ac­ter­ized by soft­ness, so oth­er met­als are added to alloys to cre­ate prod­ucts from it. Addi­tives strength­en it, change the shade and smooth the sur­face. The com­po­si­tion of the pre­cious met­al in the alloy deter­mines the assay of the jew­el.

In many coun­tries of the world, includ­ing Ukraine, there is a met­ric sys­tem that char­ac­ter­izes the num­ber of parts of a noble mate­r­i­al in 1000 units of alloy.

All prod­ucts that enter the jew­el­ry mar­ket are marked with a stamp that deter­mines which part of the alloy the pre­cious met­al is. If there is no sam­ple, it means that it is an ille­gal­ly import­ed fake of dubi­ous qual­i­ty or an arti­sanal prod­uct.

The jew­el­ry mark informs buy­ers about the ratio of the weight of the pre­cious met­al in the alloy to the total weight of the alloy. The high­er the test, the high­er the con­tent of pure met­al in the alloy. The high­er its per­cent­age in a giv­en sam­ple, the high­er its val­ue and val­ue.

A sam­ple of a pre­cious met­al is always marked with three num­bers that show how much of it is in the sam­ple. Since the num­bers are ppm, the sam­ple is trans­lat­ed into thou­sandths of a gram.

There is no real pure gold. The 999 sam­ple is con­sid­ered the high­est. Its alloy con­tains 99.9% gold, 24 carats. It is sold in ingots of 2, 5, 10, 25, 50 g and in coins.

Gold 585 is an alloy con­tain­ing 58.5% pure gold.

The rest are impu­ri­ties of oth­er met­al alloys that give it strength.

What does 585 proof gold mean in the world and in Ukraine?

In Switzer­land, the Unit­ed States of Amer­i­ca, and the Unit­ed King­dom, there is a carat sys­tem, accord­ing to which a 1000th sam­ple of the pre­cious met­al cor­re­sponds to 24 con­ven­tion­al units. That is, gold 585 proof, which means its val­ue is 14 carats.

Ukrain­ian-made prod­ucts must be stamped with the stamp of the State Inspec­torate and the man­u­fac­tur­er’s stamp.

The 1st num­ber shows the year of brand­ing. The let­ter fol­low­ing it is the code of the State Assay Inspec­tion. Fur­ther let­ters indi­cate a spe­cial code of the man­u­fac­tur­er.

585 and 333 tests of gold: what they mean and how they differ

It is dif­fi­cult for a sim­ple buy­er, who is not a jew­el­er, to dis­tin­guish jew­el­ry made of gold 585 from 333 by appear­ance, if he does not know how much pure gold is in 585.

The cost of the same mod­els made of pre­cious met­al of dif­fer­ent alloys is dif­fer­ent.

Jew­el­ry made of 585 gold is jew­el­ry that con­tains more pure gold, so the price of ear­rings or a chain will be high­er than sim­i­lar prod­ucts of 333.

Anoth­er dif­fer­ence between 585 and 333 gold is hard­ness and dura­bil­i­ty. Prod­ucts with the 333 stamp have high strength and resis­tance to dam­age and scratch­es. But if they are not used for a long time, they dark­en and lose their shine. The 585th sam­ple is gold, any dark­en­ing and con­t­a­m­i­na­tion from the sur­face of which can be eas­i­ly removed with a spe­cial soft cloth. Jew­el­ry made of it is par­tic­u­lar­ly strong, which is more appre­ci­at­ed by buy­ers.

What does 585 proof gold of different colors mean?

As in the entire post-Sovi­et space, there is a wide­spread opin­ion in Ukraine that the high­est qual­i­ty gold has a red-yel­low hue. Met­al of a dif­fer­ent col­or is either more expen­sive or worse in qual­i­ty. This explains the fact why it is less pop­u­lar in our coun­try than in the coun­tries of the Euro­pean Union.

How­ev­er, the shade of gold does not depend on the sam­ple, but on the lig­a­ture — com­po­nents that are added in clear­ly defined pro­por­tions to the com­po­si­tion of the alloy.

At the peak of pop­u­lar­i­ty — jew­el­ry made of bright yel­low, as well as white gold with a rhodi­um coat­ing. The beau­ty of prod­ucts made of rose or red gold alloy with zinc, sil­ver and cop­per impu­ri­ties is also in demand.

Mod­ern jew­el­ry made of an alloy of white gold and pal­la­di­um is becom­ing pop­u­lar. This is a hypoal­ler­genic met­al that is suit­able for the most sus­cep­ti­ble cus­tomers. For today’s fash­ion­able engage­ment rings with dia­monds, the white col­or is most often used, which clear­ly empha­sizes the shine of the stones. Plat­inum and white gold are eas­i­ly dis­tin­guished by the yel­low­ish tint char­ac­ter­is­tic of gold, but the rhodi­um coat­ing hides this dif­fer­ence.

The world instant­ly fell in love with red gold thanks to the Dami­ani jew­el­ry house, which released a col­lec­tion of ros­es from it.

Min­i­mal­is­tic white gold began to be worn every day after the appear­ance on the mar­ket of the mod­el line of the Tiffany brand.

The “Trin­i­ty” series from Carti­er awak­ened the pas­sion­ate desire of all fash­ion­istas to have a ring, pen­dant or bracelet made of a com­bi­na­tion of three dif­fer­ent shades of gold.

Resis­tant black gold is one of the newest jew­el­ry trends. A beau­ti­ful black-sil­ver shade occurs when prod­ucts are coat­ed with black rhodi­um or ruthe­ni­um is applied by gal­van­ic method, as well as by adding chromi­um or cobalt to the lig­a­ture.

The famous “choco­late” Boucheron wed­ding rings are made from brown gold based on a cop­per alloy with potas­si­um sul­fide.

The tech­nol­o­gy of obtain­ing pur­ple (amethyst or pur­ple) gold with the addi­tion of alu­minum came to Ukraine from Sin­ga­pore.

585 gold is an alloy of dif­fer­ent shades, which deter­mines the ratio in the com­po­si­tion of non-fer­rous met­als. Thanks to 36% sil­ver and 5.7% cop­per, gold acquires a green­ish tint, 18.3% sil­ver plus 23.4% cop­per — pink, 8.3% sil­ver and 33.4% cop­per — red.

For the pro­duc­tion of pre­cious jew­el­ry, man­u­fac­tur­ers most often use white gold con­tain­ing 23.7–28.7% sil­ver, 13.0–18% pal­la­di­um or 17% nick­el, 16% cop­per, 9% zinc.

Now you know that gold of 585 proof, or rather, why jew­el­ry made of it costs more than 500, 417, 375 and 333 proof prod­ucts.

The cat­a­log of the Sil­vers online store presents many inter­est­ing options for gold prod­ucts for every taste — from elite jew­el­ry to sim­ple and styl­ish acces­sories for every day. Choose gold jew­el­ry that suits you per­son­al­ly!
