  1. 2019年10月26日 · 天女,由日本真珠科學研究所命名,代表了白色系akoya珍珠中的卓越品質。 日本真珠科學研究所所長小松博在2001年發現,在珍珠專用鑑定儀器的觀測下,可以看到在優質akoya珍珠下半球會出現3種干涉色,即“極光效應”。 具備了“極光效應”的akoya珍珠且直徑在6mm以上的,即命名為“極光天女”,一般簡稱為“天女”。 關於珠層: 天女珠層的標準為0.4mm,0.4mm以下的不可評定為天女。 很多賣家宣稱,珍珠層越厚珍珠光澤越美,很多買家也深以為然。 然而事實並非如此。 珠層並非越厚光澤越好,珠層厚度與光澤、瑕疵沒有直接聯繫。 決定珍珠光澤的是珍珠質單層結晶層之間的排列疊加是否平整緊密。

GROUP LIMITED的一個飾品品牌,由2009年開始與前任GIA鑽石鑒定師一同創立及研發新形寶石材質以"RZ"命名。 也因為Roselle Jewelry的宗旨是讓天下的女人都可以擁有鑽石般完美的寶石,經過多年的獨家研發到2015年終於完成最完美的RZ ® 人造鑽石並保證肉眼100%與鑽石相符。 我們專業的RZ ® 人造鑽石 已經可以完美替代鑽石的存在,並且有品牌專利的存在。 無可否認我們是獨特及精緻的。 同期開立第一間實體店於香港尖沙咀及銅鑼灣以讓顧客能夠親身體驗及對比天然鑽石與RZ ® 人造鑽石 之間的區別。 品牌理念.

  3. 2019年10月26日 · 天女項鏈. 關於天女,您要承知. 天女,由日本真珠科學研究所命名,白色系akoya珍珠中的卓越品質を代表する。 下半球會出現3種干涉色、即ち“極光效王”。 具備“極光效王”のあこや珍珠及び直徑在6mm以上、即命名為“極光天女”、一般簡稱為“天女”。 於珠層: 天女珠層の標準為0.4mm,0.4mm以下の不可評価為天女。 很多賣家宣稱,珍珠層越厚珍珠光澤越美,很多買家も深為然。 珠層並非越厚光澤好,珠層厚並光澤,瑕畝有直接聯繫。 決定珍珠光澤は珍珠質層結晶層間の配列加重が平坦密であるかどうかです。 例例,就如同層一層的磚塊疊加,磚塊集合列整齊緊密,那這面牆就平整筆直而結實,如果磚塊排列不整齊,那這面牆就會凹凸不平很不美観。

    • How Are Lab-Created Diamonds Made?
    • Lab Grown Diamond Benefits
    • What Colors Are available?

    Each laboratory-created diamond is grown by placing a diamond ‘seed’ into a chamber of heat and pressure. This chamber mimics the natural growing process. Crystallization occurs allowing the lab-grown diamond to mature within six to ten weeks. It is then cut, polished and graded by the same world-renowned labs that certify earth-mined diamonds. The...

    UNMATCHED BEAUTY

    Our collection of lab-created diamonds are available up to IF in clarity, D in color, Ideal in cut, and up to 10 carats in size. They come in a variety of shapesincluding round, rose, emerald, cushion, oval, oval rose, heart, princess, trillion, and radiant. Colors include white, yellow, blue, pink, and green.

    UNRIVALED QUALITY

    Unlike other retailers, every Rooselle Jewelry lab-created diamond is Type IIa, the purest form of diamond. They are harder and more brilliant than Type Ia diamonds. Only 2% of earth-mined diamonds are of this quality. Furthermore, each diamond is graded and certified by the same leading independent gemological labs that are used to grade earth-mined diamonds.

    UNBEATABLE VALUE

    Lab-created diamonds cost up-to 40% less than their mined diamond equivalents. Buyers beware: keep an eye out for "grown diamonds" sold for a few hundred dollars per carat. If the deal seems too good to be true, it probably is. Only diamond simulantsfall in this price range.

    WHITE LAB-CREATED DIAMONDS

    A pure carbon diamond with no impurities will grade as a colorless diamond. However, the majority of both mined and lab-created diamonds contain impurities, most of which are nitrogen. The nitrogen atoms within the diamond lattice create the yellow tint. In cases of fancy colored diamonds, a pure yellow color is created. Nearly all diamonds, both mined and lab-created, start out as yellow diamonds. Over the span of millions of years and exposure to pressure and heat, mined diamonds split the...

    YELLOW LAB-CREATED DIAMONDS

    Roselle Jewelry’s yellow lab-created diamonds are optically, chemically and physically identical to yellow earth-mined diamonds, but are offered free of conflict and on average 10% of the cost. They are available in a color range from fancy yellow to fancy vivid yellow, in sizes up to 2.0 carats and a variety of shapes. Both mined and lab-created yellow diamonds get their color from nitrogen. While diamonds are made up of carbon, impurities within the stone exist. It is the introduction of th...

    BLUE LAB-CREATED DIAMONDS

    Blue lab-created diamonds are optically, chemically and physically identical to blue earth-mined diamonds and are offered free of conflict and about 10% of the cost. They are typically offered in sizes smaller than 1.50 carats and come in a color range of fancy light blue to fancy intense blue. Both mined and lab-created blue diamonds get their color from boron. While diamonds are made up of carbon, impurities within the stone exist. It is the introduction of these impurities, in this case bo...

  4. 2019年6月26日 · Watch on. 與莫桑石對比呢? 莫桑石並非鑽石切割也並非與鑽石一樣的材質。 現在很多商家都只會網上發售,因為一有鑽石對比的話基本上就看出分別。 然而有些人會話可以過鑽石筆,其實一般顧客不可能容易購買到鑒定用的鑽石筆,而現在新型的鑽石筆已經可以能夠分辨莫桑石及鑽石。 可以查看下面短片: 最左莫桑石,中間鑽石,右邊RZ人造鑽石. RZ人造鑽石在短片中與鑽石看起來都是完全無區別的,只有使用鑽石筆的情況才會分辨出來。 而莫桑石在肉眼下已經清楚能否分辨兩者區別。 Roselle Jewelry- 莫桑石和RZ人造鑽石及天然鑽石 測鑽筆及對比. Watch on. 後記: 那是否要蓋著光去比較自己的仿鑽和我們的仿鑽?
