Nearly 28-Carat Pink Diamond Found in Russia

Alrosa-27.85 carat pinkMoscow--Alrosa reported this week that subsidiary Almazy Anabara has recovered what is by far the largest pink diamond in company history.

Weighing 27.85 carats, the rough diamond has dimensions of 22.47 x 15.69 x 10.9 mm, and is described by the company as being “of gem-quality and almost free of inclusions.”

Prior to this find, Alrosa said the biggest pink diamond it had ever recovered was 3.86 carats. That too was discovered by Almazy Anabara, which recovers pink and other natural color diamonds at the Severalmaz kimberlite pipes and placer deposits.

Apart from that stone, which was found in 2012, Alrosa has found only three pink diamonds weighing more than 2 carats over the last eight years.

This week’s news of the recovery of a nearly 28-carat high-quality pink follows the company’s August unveiling of the five polished diamonds it cut from a colorless 179-carat piece of rough it found in 2015 and dubbed “The Romanovs” diamond.

The largest of the stones is a 51.38-carat round brilliant, D color, VVS1 clarity diamond with triple excellent cut. Called “The Dynasty,” it is the biggest stone of this quality ever cut by the company.

Commenting on The Dynasty, Alrosa said: “This stone gives a start to a new stage in the development of Alrosa’s cutting division that will actively develop polishing of extra-large and colored diamonds. The Dynasty demonstrated that we can do it at the highest level.”

But whether the company will apply these cutting skills to the newly discovered pink diamond remains to be seen.

In a news release issued Thursday, Evgeny Agureev, the head of USO (United Selling Organization) Alrosa, said the company’s polishing division is examining the diamond in order to decide whether to cut it or sell it rough.

“Large stones, particularly colored, are always in demand at auctions. But if the company decided to cut it, it would become the most expensive diamond in the entire history of Alrosa,” he said.

Clean Your Jewelry | Diamond Source of Virginia

Learn the proper cleaning process for each jewelry item since different gemstones and metals have different characteristics.

  • Metal and stones used in costume jewelry are generally not as durable as most fine jewelry.
  • When in question about a particular type of gemstone or metal type, a quick online search for cleaning that item online will probably provide the specific guidance you need.
  • Ultrasonic cleanerA home ultrasonic cleaner can be used for diamond, ruby, sapphire, citrine, blue topaz, peridot, aquamarine, garnet, and amethyst.
  • A home ultrasonic cleaner or harsh abrasive cleaner should not be used for pearl, opal, emerald, tourmaline, Tanzanite, turquoise, amber coral or onyx.
  • Metal watch bands can be cleaned with an ultrasonic cleaner but be careful not to put the watch mechanism under water even if says it is water resistant.

Hand creamAvoid touching cleaned diamonds with your fingers as the oil from your skin can cloud the stones. This is especially true if you have hand cream or moisturizer on your hands. Oil and hair products can also coat diamond earrings so they should be cleaned regularly to stay bright and sparkly.

Beware that some do-it-yourself remedies like witch hazel, bleach, vinegar, and baking soda can damage your jewelry

Red, white or blue jewelry (rubies, diamonds, sapphires) with gold or platinum metals are relatively durable for cleaning.

The best homemade jewelry cleaning solution is a mixture of a few drops of Dawn dish detergent in warm water. Soap the jewelry item in the solution for a few minutes and then brush with a soft tooth brush, rinse in clean warm water, then dry with paper towel or lint-free clean cloth.

Jewelry cleaner kitYou can also buy one of the brand-name liquid jewelry cleaners online or in most department stores, which usually include a container of cleaner, a basket to soak the ring in and a small brush to clean hard to get at areas. Read the label and follow its instructions.
