Most of the Ruby found on the market these days have had some form of treatment applied to them. How do they treat Ruby gemstones and what does it do to the stone? Some of the treatments have names like “Heat Treatment”, “Glass Filling”, “Clarity Enhancement” or “Beryllium treatment”. On GemRockAuctions it is essential that all Rubies have their treatments listed correctly as it can have a drastic affect on the price of the gem.

What does “Treat Ruby Gemstones” Mean?

During the process of getting Ruby from the ground to the final customer, most stones need to be altered by a treatment in order for it to be commercially acceptable. Treatments can improve the colour and clarity of Rubies which make them more desirable in the final market. In a nutshell, “Treat Ruby Gemstones” means to alter the Ruby in some way in order to make it more beautiful.

What Are The Ruby Treatments?

A treated Ruby is not a bad thing. Less than 1% off all Rubies that are recovered from the ground actually make it to the market without any treatment. These are the most precious and value Rubies available. If they did not treat Ruby gemstones, 99% of the Ruby would never make it to the market. That means the average person may never see a Ruby in their whole life if it was not for treatments.

Untreated Ruby

By far the rarest and most valuable Ruby gemstone. These stones ave been mined out of the ground, cut and polished and presented to the market. No other process apart from cutting and polishing has been performed on these Rubies.

Heat Treated Ruby

This technique has been used for centuries to treat Ruby gemstones. It is used to improve the clarity and colour of Rubies. The Ruby is placed in a crucible and heated to extreme temperatures of around 1800 degrees. The atmosphere around the Ruby can be altered to change the way the Ruby reacts but the basic idea is that the heat will dissolve any rutile inclusions inside the stone which will improve the clarity and improve the red colour. No other additives have been added to the process and the Ruby is as strong and durable as the unheated version.

Flux Healed Rubies

Sometimes during the heating process, the Ruby will be coated in a flux material. The purpose of this material is to stop multiple Rubies sticking together when heating and acts as a barrier. The down side is that this flux material can melt and penetrate any cracks or fissures in the Ruby. This will improve the clarity of the Ruby by filling in the cracks, but it will decrease the value of the stone since it is a foreign material.

Beryllium Diffused Ruby

This treatment is more commonly used on Sapphire rather than to treat Ruby gemstones. The Rubies are heated while Beryllium is added to the crucible. The Beryllium diffuses with the crystal lattice of Ruby and can create a more intense colour.

Glass Filled Rubies

This is the newest and most commonly seen treatment of Rubies in the market place today. Low grade Ruby is used that is full of cracks and fissures. It is bleached and then heat treated with the addition of a liquid glass. This glass penetrates the Ruby and improves the clarity by reducing the amount of visible cracks on the surface. This treatment is not very stable as temperature changes, ultrasonic cleaners and shock can cause the lead glass to fall out of the stone.

什麼是紅寶石療法?

處理過的Ruby不是一件壞事。所有從地面上回收的紅寶石實際上沒有任何處理就可以進入市場,低於1%。這些是最珍貴和最有價值的紅寶石。如果他們沒有對待紅寶石 ,那麼99%的紅寶石都不會投放市場。這意味著如果不是為了治療,普通人在一生中可能永遠不會看到Ruby。

未經處理的Ruby

迄今為止最稀有和最有價值的紅寶石寶石。這些石頭已經從地下開采出來,切割並拋光並投放市場。除了切割和拋光以外,沒有其他工藝在這些紅寶石上進行過。

熱處理紅寶石

這種技術已被用於治療紅寶石的幾個世紀。它被用來改善紅寶石的清晰度和顏色。紅寶石放在坩堝中,加熱到1800度左右的極端溫度。 Ruby周圍的氣氛可以改變,以改變Ruby的反應方式,但基本的想法是,熱量會溶解石頭內的任何金紅石包裹物,這將提高透明度和改善紅色。沒有其他添加劑被添加到該過程中,並且Ruby與未​​加熱的版本一樣堅固耐用。

助焊劑癒合的紅寶石

有時在加熱過程中,紅寶石將被塗上一種助焊劑材料。這種材料的目的是阻止多個紅寶石在加熱時粘在一起並作為屏障。不利的一面是,這種焊劑材料可能會熔化並穿透Ruby中的任何裂縫或裂縫。這將通過填充裂紋來提高Ruby的清晰度,但由於它是一種外來材料,它會降低石材的價值。

鈹擴散紅寶石

這種治療方法更常用於藍寶石而不是治療紅寶石。將鈹加入坩堝時加熱紅寶石。鈹與紅寶石的晶格擴散並可以產生更強烈的顏色。

玻璃填充的紅寶石

這是今天市場上最新和最常見的紅寶石療法。低品位的紅寶石被使用,充滿了裂縫和裂縫。它被漂白,然後加入液體玻璃進行熱處理。這種玻璃穿透紅寶石,並通過減少表面上可見裂紋的數量來提高清晰度。由於溫度變化,這種處理方式不是很穩定,超聲波清洗機和電擊可能導致鉛玻璃從石頭中掉出來。
