What's New in DiamondMaster

7.0.1

November 3, 2026

SAME DIAMOND QUALITY. A WIDER WORLD OF VALUE. Version 7.0.1: in addition to bug fixes this update expands DiamondMaster's subscriber selection from 13 to 27 Cost units, bringing more ways to compare Mined-Natural and Grown-Created diamond reference values, and changes between cost units - revealing the true reality of wealth: letting you see instantly whether your diamond is genuinely appreciating, or if your chosen currency is losing its purchasing power. MORE CURRENCIES Compare in 12 fiat currencies, including the addition of the South African rand (ZAR). MORE PRECIOUS-METAL REFERENCES Explore gold, platinum and silver by troy ounce. Gold also has dedicated gram, 100-gram and kilogram choices: Denari (XDEN), Centum (XCEN) and Milia (XMIL). CRYPTO COMPARISONS Express diamond reference values in BTC, ETH, LTC, ADA, SOL, PAXG and ZEC, alongside currencies and metals. A NEW SOVEREIGN BASKET PERSPECTIVE Explore XUNT, DiamondMaster's calculated reference for the proposed gold-and-currency BRICS+ "THE UNIT" basket (XUNT), alongside the IMF's Special Drawing Right (XDR). Follow the East's core decentralized unit who's value that is backed by 40% physical gold held in Central Banks vs the West's core centralized unit (IMF/Federal Reserve) that is backed by debt of 5 top global economies debt/FIAT weighted according to GDP. DAILY EXCHANGE-DATA REFRESHES Currency, metal and crypto reference updates bring a broader exchange perspective to your calculations. Refreshes depend on connectivity and source availability; earlier saved or supplied values may remain in use. PUT THE NEW UNITS TO WORK Keep the same diamond classification and switch Cost units. Natural-diamond screens show 1-year and 5-year percentage changes in the selected unit where positive gains-appreciation-inflation are displayed in green, and negative losses-devaluation-deflation are displayed in red. The Global Value Adjuster now has a higher range to apply a preferred discount or premium for your use: if buying or selling for wholesale, retail valuation, cash-estate values, to distress liquidation. Historical BRICS+ XUNT comparisons earlier than the "Pumpkin" October 31, 2025 cast date are reconstructed and the refreshed PAXG 5-year reference (before PAXG's minting date) uses gold as a proxy. Historical percentages are available for natural diamonds; lab-grown screens show per-carat and total reference values.

Diamond Pricing

Now the bugs have been fixed, this app is awesome! Calculates the wholesale price of “mined” diamonds AND the first and only app to calculate wholesale price of “lab grown” diamonds quickly and easily. I love this app and recommend the 1 year subscription to keep your finger on the pulse for the latest wholesale diamond price list.

Great value

I use this app every day in my work as a jewellery appraiser, it gives me instant access to prices on a wide selection of stones and when I found a large stone that was not covered by the list I contacted Wayne directly and he was able to do some research in the US. Very very helpful I regularly recommend this to my friends. Used in conjunction with other sources I feel very confident with the prices I arrive at

Very useful

I used this when buying a ring for my wife. Useful to compare the effect the 4 c's have on price. You enter your country's currency and vary the percentage markup to coincide with the online place your purchasing from and then start selecting.
